That's not atypical. The forced air is seeking the path of least resistance, so more of it will come out of the vents closer to the A/C unit. There is only so much you can do, unfortunately, without having the HVAC company redo some things, but there are a couple of tricks you can try.
One is to partially shut/cover the vents closer to the A/C, in the hope that more cold air will be diverted to the back of the house. Another is to use some fans inside the house, to move the air around.
You can also try installing some register fans, in the back of the house, in the hope of pulling more of the cold air back there. I've never used them, personally, but some people love them; ultimately, I think it depends on the setup of the house and the HVAC system, but for the cost, it might be worth trying. Here's an example, on Amazon:
I can give you the basics:
A 6" inline EM driven fan (quiet compared to standard inline fans, and about 3x the price)
2' of 6" straight duct.
A 14" inline filter box.
Cabinet from Ikea with some slots cut into it.
Mount everything using a small piece of rubber (in the cabinet) to further reduce vibration and noise.
You can more precisely control the speed with https://www.amazon.com/Electronic-Controller-Variable-Adjuster-Hydroponics/dp/B07T9BLJ7L/
Some people have had great results with simple secondary booster fans registers, like this one:
Might be worth give it a try, before attempting a major overhaul of your system.
Register booster my dude. They are "dumb" but they work. https://www.amazon.com/AC-Infinity-Register-Thermostat-Control/dp/B0792QR5YT/
I would much rather have smart vents but I'm in the same scenario as you and don't want to spend the money to deploy them in the whole house.
If its just too much vibration you can use a fan controller to fine tune the speed. https://smile.amazon.com/gp/product/B07T9BLJ7L/ assuming it's the corded model.
Will second this. I bought this one:

And on the lowest/slowest setting, it's very quiet and a deep rumble that feels amazing.
AC Infinity CLOUDLINE T6, Quiet 6” Inline Duct Fan with Temperature Humidity Controller - Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics https://www.amazon.com/dp/B074XBXFPD/ref=cm_sw_r_cp_api_glt_fabc_SJ2H94S5PRHY9GJ39KS7 here is the Amazon use CANUCK15 for a discount code
There's inline fans like these.
Here's a shutter exhaust fan with temp control.
This right here, plus some 4" dryer hose would easily vent out any harmful stuff. If you were the clever sort, you could probably route it out with normal dryer exhaust.
That's not atypical, and there is only so much you can practically do about it, but I'll offer a couple of suggestions.
up to a good start...
not sure what power is your light... but i used a 6'' vivosun inline booster fan for my 5x5 with a 400w hps and it sucked the air out quite fast, a bit noisy should be more than enough for any hps and was pretty cheap compare to the usual inline fan.
and you can buy a speed controller for cheap on amazon too.
These are perfect! Thank you! Now I won’t need to wire a new switch if I use one of these inline fans.
Yes, 4" exhaust fan should do it. I would also leave the doors open during lights on so that the heat isn't all trapped in the closet. But that's just me. If noise is an issue I'd go with AC Infinity.
If it's not and cost is more your concern, something like this might be better for you.
I'd be more inclined to get two smaller fans rather than one big one, but that's only because I like to control every detail and I'd be treating each tent as its own environment even though they're right next to each other.
How large of a tent can you fit?
Like the other guy mentioned, AC Infinity is swinging hard in to the grow industry right now. They even have an LED light coming out REAL soon that I will be purchasing on release. I suggest their equipment from my experience.
No matter what tent or anything else you choose, I will 100% say that in my opinion and I would be willing to bet on most anyone else that has used it, the AC Infinity Cloudline inline fans are absolutely the best buy for the money. They are also very quiet compared to fans I've used. https://www.amazon.com/dp/B06ZXWN3BG/ref=cm_sw_r_apan_glt_fabc_KHXV23N3A5QKVCPDTQ6T
They automatically kick on and off depending on the environment rules you set.
i.e. humidity set at 60% and temperates set at 80°f means that any time the sensor detects that your tent gets hotter or more humid than that, it kicks on and vents out your tent till it's back in spec. It's SOOOOO NICE to have that autonomy.
You can just get a regular in-line fan it’s a lot cheaper. Not sure if that would help you or not if the ductwork is falling apart it may not help you at all. If you want to put a booster fan in this is what I would get in your situation

This is my duct fan. Im about to order a 2nd one soon. One to pull air in at the bottom and the other w a carbon filter to pull air out the top.
That was exactly the problem, it wasn't! The builder we chose is in central California and clearly did not have experience with the PNW climate. The ductless range hood fan was just spreading all that humidity from cooking right back into the house. I installed a 6" booster duct fan, ducting and a dryer duct cap vent on the outside of the house. I also put in a 4" inline duct fan with carbon filter for fresh air intake, routed to release directly above the split intake so A/C & heat are both using fresh air. We also use a dehumidifier listed for 1500 sq. ft., even though our house is only 240 sq. ft. Humidity tends to hover around 35-40%. An ERV system would probably be better performing but is difficult and expensive to install if the house is not designed for it. My DIY solution cost about $300 or so and works quite well. An ERV is more like $1,000.
After 1 month we went to flip the mattress over (bedroom loft) and it was covered in mold! Of course we had laid it directly on the loft floor because we had no idea that is like the perfect place for mold growth (heat from our bodies combined with cool, uninsulated surface of loft equals condensation). Now we have an open cell mattress underlay that lifts it up 1/2" and allows air to flow around.
There are lots of blogs and youtube videos available about mold in tiny homes, we just didn't think to look into it because we always lived in normal sized houses where it's not an issue.
One thing I didn't see in the comments(or missed), be cautious about closing to many vents. It can cause too much back pressure on the blower fan and prematurely wear out the fan. Also, it is not recommended to run your fan 100% of the time. It doesn't allow the condensate to drain off the EVAP coil when the AC is running. Which can cause mold and will only put the humidity back in the air. I turned that function off and have saved money and been more comfortable during the summer. What I did to help with temp differences was install a vent fan. It replaces the register cover with a programmable fan to help pull conditioned air in the room. It help a lot. https://www.amazon.com/dp/B0792QR5YT/ref=cm_sw_r_cp_apa_glt_fabc_X6ME3G3VC1B93YM5M80F

Trust me you’ll be glad you got this!
If you have flex ducts, you could try an in-line fan like this. The key is forcing air through your existing system. You might also want automated registers to open and close vents in other parts of the house. Basically there’s all sorts of tech around AC efficiency to help cool/freshen certain rooms.
Try this for your daughters room: works very well

Btw I just added an ac infinity t4 inline fan w/ 4” carbon filter, it’s pretty awesome. It’s fairly automatic, “set it, and forget it” as I like to say. I just enter the rh% & temp highs and lows, and the fans kick on when it reaches that zone. It has also eliminated the smell completely outside of my tent which has been awesome. It’s legal in my state but I still want to be discrete.

I run it in the tent where the fan pushes air through the filter out the tent and it creates negative pressure contributing to smell prevention
PC fans might work but you want to be able to have it powerful enough to suck the air from the box into the tent or the smells with just leak out of the little gaps and cracks. I guess it depends on the size of the box you're using. I use this fan which may be borderline overkill but it works pretty good.

Look cloud line A/C infinity. They are insane with performance and my is only a little loud, like less than my clip on fan, on the highest setting and I use the filter sleeve it came with so it’s pulling even harder.

I bought it off amazon.

And here is the ducting: https://www.amazon.com/gp/product/B072SH65FN/ref=oh_aui_detailpage_o04_s02?ie=UTF8&psc=1
I had Temps around 85F so what I did was bought a booster fan, hooked it up to a piece of ducting. I put the fan in the tent and ran the ducting to a nearby AC unit. This dropped my temp by 8-10 degrees and my humidity became easier to control.
Tents cheap, $100 maybe, horticulture lighting is the brand.
It's an ac infinity 6 inch inline https://www.amazon.com/dp/B074XBXFPD/ref=cm_sw_r_cp_apa_i_KAImFbSH4S6N2
I run just a basic vivosun filter, as I have found that no matter what route you go, they go bad around the same time anyways. I would rather spend $50 every 6 months than $100 every 8 months for a better filter. If that makes sense?
With my fan I just set desired temps and it adjusts CFM to match the range I set. It works well, up to like almost 400 CFM, but that's reduced by ≈25-30% with the filter attached
300 for a t4 isn’t a good deal. Amazon has them for 120-250 for the t4-t8. I think you have a t6, but you can tell because the diameter is the same as number. If you do have the t4 go ahead and order yourself some 4”-6” adapters and start running 6” vents. I have a t4 and that helped me a ton!

I’ve never built one, but a 6” in-line fan with a fan speed controller sounds like what you’re looking for? That’s a link to a fan speed controller. You can turn it up or down to adjust your flow to what you’re looking for vs just an On and Off position.
I was tired of noisy fans too so I installed this in the attic to pull air from the vents out in-line. It’s totally silent. I have mine programmed to start when the humidity jumps up from the shower. I left in the noisy fan for the shy poopers. They can turn that on with a switch like usual.
I've been using air infinity fan booster registers and they help a lot.
Aside from this I'm not sure what else to try. My upstairs is always a good 5 or more degrees hotter then my bottom two levels.

You could get something like this. But it might just be cheaper to buy a new fan. I don’t believe this would damage your fan but I can’t know that for sure.
Are you sure you meant CBM? I'm not sure what that stands for. CFM (cubic feet per minute) is the usual imperial measurement of airflow. The metric measurement is cubic meters per hour. 7 CFM seems reallly low. Like, your average $10 computer case fan moves 5x as much air.
There are a lot of factors that can go into picking a fan. I've linked the fan I bought when I built my spray booth, but I'll be blunt and say it's absolute overkill. I was building a full fume hood for multiple use cases, and I wanted something that was quiet, and I wanted variable speed so I could control how loud/sucky it was, and I wanted a higher CFM to compensate for how long the ducting runs were going to be.
Fair enough. Last thought since fan is max'd. Install these register's everywhere they are cold (probably the whole perimeter). These will ensure they get their share of the air being pumped in. They can also mitigate the air sealing aspect by making the plenum more neutral.
Also, if the heat pump has enough capacity for the house ducted, then it has enough capacity for it to be a plenum. You just got to work around the situation.
At the end of the day, if the plenum is insulated as good as the walls, it isn't a problem and can be worked around easier than retrofitting in ductwork at this point. Would I have ducted it day 1, yes. But that doesn't mean we have to duct it now.

It's weird because I thought they don't either but mine seem to love it. It might entirely be because of the temperature like you said though. I have this slightly more advanced grow tent my Uncle Ben's bags are in where I have this temperature control thing I put within it so that also might be helping because I've closely been monitoring that thing. Thank you!! I wish the best of luck to you!
Would something like this work? I mean, the motor is in the airstream, so maybe not. Though maybe it'd work as an eductor, creating the bypass airflow that sucks the fumes out of the booth? I feel like I described that poorly. . .
Please dont stack a ton of pre filters to slow down the flow like has been recommended so many times here. Youre just going to put a lot of unnecessary extra load on the motor. All you need is one of these

The ultimate option imo is a grow filter. I got this fan and this filter on Amazon and a rubber coupler at home depot. It removes all smells.
Is it overkill? Probably. But after a landlord run-in I decided not to fuck around. Dry herb vapes are just an oven baking an herb. Of course it smells. Think about how long your apartment smells after cooking food with lots of herbs and spices. And if you're vaping you'll get noseblind easier.
A year ago, I bought their 130W behemoth. I ran it with the "stock" configuration for a couple of months.
The first thing I noticed was how much wood smoke was coalescing in the machine during use. I mean....billowing... The OEM box fans weren't keeping up at all, and I was having to clean my mirrors and lens, and the plexiglass lid every single day or there was a noticeable loss of efficiency. And I was using it for hobby use!
So, I bought a pair of these: https://www.amazon.com/gp/product/B07FPFVZTZ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
And now my work pieces stay clean, my mirrors stay clean, and my plexiglass lid stays clean! They made a massive difference in the maintainability of my machine.
It's my opinion that MORE IS BETTER, when it comes to air assist, and to exhaust capacity.
​
On your tube temperature control - you get a choice. You can invest the money into a chiller that maintains proper tube temperature, or you can invest the money into replacement tubes.
With a bucket and a submersible pump, you will eventually grow complacent about the water temperature. It WILL eventually happen. And the tube will punish you for it.
So don't wait too long on making the investment on a chiller. The chiller can make the difference between annual tube replacement and replacing a tube every 7 years.
They all look pretty much the same and this was the most affordable one I've found.
They sell one specifically for the Hitachi/magic wand under the wand essentials brand (with a blue dial) but all the recent reviews say it is crap and does not work. Mine is this same brand but is several years old and looks like the one above just with their logo stuck in the corner.

I’d recommend this as well. I have an AC Infinity T6series as my exhaust and have an S6 for my intake fan which communicates with the T6. You could use just a T6 as in intake fan but ideally you want negative pressure pull air out so they get fresh air. I personally would set up a T6 as an exhaust fan before installing an intake fan. just to ensure negative pressure.. you’d be surprised how well a great exhaust fan can cool the tent.
I'd get an outboard fan speed controller like Nyeeeh - https://www.amazon.com/Electronic-Controller-Variable-Adjuster-Hydroponics/dp/B07T9BLJ7L/
And drive it physically with a servo or stepper motor
Cool idea, it would be cool to see how much you even need GPU fans if there was that much airflow going directly to the GPU. Can confirm this fan is super quiet on 1-5 (out of 10), I can't comment on the other sizes of fans from them.
AC Infinity CLOUDLINE T6, Quiet 6” Inline
I had almost the exact same issue on a new construction home. We solved it by using this:
AC Infinity AIRTAP T4, Quiet Register Booster Fan with Thermostat Control. Heating Cooling AC Vent. Fits 4” x 10” Register Holes. https://www.amazon.com/dp/B0792QR5YT/ref=cm_sw_r_apan_glt_i_S6K0ZYVHZY5V98C83Q27?_encoding=UTF8&psc=1
I didn't want to cut into the ductwork for a booster, as well as disrupting the balance that comes with that. This was quiet, as well as easy to reverse if it didn't help the problem. It detects heat/cold and only activates when your furnace/ac is running. It has made a world of difference in our daughter's room. I cannot recommend it highly enough.
Get yourself a light that doesn't have fans, check out here for some good quality ones. They make no noise. Get a bigger fan for the tent, run it on lowest setting, and it will be virtually quiet. I'd recommend this one and when it's running on setting 1x it still is pretty quiet. Get yourself a nice carbon filter, don't think it matters what you get, and look into LST (Low Stress Training) because you are going to have to train them if you are limited on space. Don't veg the plants too long, or you will be dealing with space issues late in flower and you don't want that. Not sure what else to tell you, besides don't grow to many in one tent if you are using a smaller one. I would start out with 1x if I were you, and make sure you keep the plants off the ground. I like to elevate them a bit and put a bin under them to collect run off so the plant stays in the same spot all flower and I don't have to move it.
So I had a similar situation. Nursery in new (40+ year old house) routinely 2-3° cooler than other rooms (according to Nest sensors). I got one of these guys:
https://www.amazon.com/dp/B0792QR5YT?ref=ppx_pop_mob_ap_share
Problem solved. It literally evened the whole house out. When I woke up, every sensor in the house was reading 69°.
What about a temperature controlled duct fan to control the temperature in the room? Then you would just have to run the duct into a filter. Maybe something like this? Then a backflow preventer (like whats used on a dryer) on the exit vent.
I like this idea. I found this fan. Do you think this would work for the printing fumes, or would I need to modify it?
> Because of the bathrooms location in the basement
> We're on a subfloor with an extremely limited space crawlspace underneath.
I'm lost, there is a crawlspace under the basement?
Regarding the distance, there are inline fans to help with that like this
SUPER SPECIAL BONUS QUESTION: Would this carbon filter work with the AC Infinity CLOUDLINE T4? It's cheaper than any 4 inch carbon filter that Amazon sells, and my understanding is that most of the carbon filters are overpriced. Just wondering if these filters are interchangable, and if it would be fine (if there's any other 4" carbon filter that you'd recommend, I'm all eyes).
I bought a 25 ft dryer hose and a cheap 4 inch duct fan
Ok thanks for the math! That’s a huge help. So you are thinking something like this baby?

The only fix I can come up with is a duct booster fan gets installed in the duct run. Gets wired to the furnace to run with the blower. If you have a newer furnace that should have EAC contacts. Wire it to that. Some come with built-in potentiometers so you can adjust the airflow. There’s a whole bunch of them on Amazon they’re not that much money

Get a cloudline exhaust fan with sensor and you can set temperature and humidity high points that it will start exhausting faster if they are hit. As long as you have a humidifier to provide humidity and a light to provide heat then the cloudline should take care of the rest. It's not perfect, but its pretty damn good. Of course you could go the other direction and get an arduino and start programming shit but thats more work than I want at home. I automated enough shit at work.
That should do it, and ignore my comment about PAR, i got this thread mixed up with another one lol!
With out a filter maybe but if ur trying to eliminate smell Because of the filter's dampering effect on the fan You're gonna need something stronger to pull the proper amount of air through the filter in the tent
I would say the minimum is the AC infinity in line T4 for that amount of space

It depends. Most newer dimmers use triacs or SCRs to reduce the voltage, but some also use PWM and turn the circuit on and off hundreds of times a second to reduce brightness.
Also depends on the motor in the air pump. If it's a pump for inflating boats or beach stuff it's probably a universal motor and can be controlled with a cheap motor controller (works like a dimmer, but higher wattage and meant to work with motors) like this one for example: https://www.amazon.com/Electronic-Controller-Variable-Adjuster-Hydroponics/dp/B07T9BLJ7L
But if it's an induction motor (heavy, quiet, doesn't use brushes) you'll need a VFD to change the frequency of the AC delivered to the motor, and VFDs aren't cheap, like 80 bucks minimum for a low power converter.
You can use something like a fan speed controller to control the power to the motor. Additionally, depending on what pedal you have, it might be a simple switch pedal that just goes 0 or 100. You can fairly easily splice a modern electronic pedal onto the cord and it comes with a built in speed control.
the rest of the basement is fine getting cooled/conditioned fine? then I would just add a 6in ducted fan to pull air out of the room. something like this:
link
cut a hole in the media room drywall, put something like this, to make it look nice, and run some ducting along the floor over to where the basement air intake is. I wouldn't bother ducting it into the existing ductwork, just dump it out in the general area.
mess around with fan position, speed, etc. until it's good, then have someone come make a drywall bulkhead to make it look nice.
you'll probably want the fan farther from the room to make it quieter.
you probably want to pull from the top of the room and from as close to the heat sources as possible.
you may also want a dehumidifier in the basement if you're going to have people down there breathing and creating humidity, but maybe your AC can handle that if you feed the air back to it.
I love the diagrams. Excellent job. I bet return air is a problem; air behaves as a fluid, and if nothing is draining from the room then nothing will want to flow into that room. Transom vents are awesome, or you can trim some of the bottom off your door to get a larger airflow gap.
Or replace your door with a screen door 😅
There is also this product https://www.amazon.com/dp/B0792QR5YT/ref=cm_sw_em_r_mt_dp_W80ZBJ6DPJDRKDTFYT4C
It's a little booster fan right in the air register.
I would 100% start by improving return air ventilation in that room, and then maybe insulate the first few registers on the trunk line... I've slid a piece of foam board insulation in a register to block it off before, maybe if you block off your daughter's room the house will equalize a bit better.
Then the little booster fan might be worth a shot, too.
I just ordered this for my 3x3 tent
6inch blower fan with control.
Hard to say, typically you want fans that are more of a centrifugal fan blade (like those used in computer laptops rather than desktop PC), which can create higher static pressure. Personally I use this beast of a fan but its significantly strong than needed: https://www.amazon.ca/gp/product/B07JB292JC/ref=ppx\_yo\_dt\_b\_asin\_title\_o01\_s00?ie=UTF8&psc=1
So a few things.
Look at the T6, not the S6.
Second, don't try to light the whole tent at once. If you do a couple of smaller boards, you can stagger your light purchases. You'll get off the ground and growing faster, save some bucks and you can always buy another light down the road.
One QB 240 could grow 2-3 autos depending on how you arrange them in the tent.
I had a similar experience with the same setup. I now use an 8" inline fan with a small extension that a colander sits in. As soon as the cycle is done, I hit cool then immediately dump into the colander with the fan on high and stir the beans constantly. The beans are usually cool to room temperature in about a minute and a half
There's this vent thing we got it, it helps boost the cool air in the ducts. With the fan it helped us cool down.
I installed a thermostatic vent fan in our nursery. Since it's the furthest room from the furnace, hardly any air makes it. The fan boosts the air when it senses the temperature change from the furnace. vent fan
You can try a register booster fan, like this one:
https://www.amazon.com/AC-Infinity-Register-Thermostat-Control/dp/B0792QR5YT
They do work and do help--but not for every house and every system. But for the cost, it's often a simple and fairly inexpensive first thing to try.
If a/c is cold get a fan mounted on the register to pull in more cold air similar to this

maybe kinda janky, but you can get inline fans that are meant for exhausting heat from long dryer vent runs and stuff like that. You could get some dryer hose, and rig up some way to catch the warm air and direct it into the hose and let the inline fan suck it out.
There are tons of different things like this...

There also is one (6") Somewhere on Amazon that has just a basic speed controller and is cheaper. About 110.

The only thing I had to do is take off their zip ties and put on stronger hose connectors - it did leak everywhere the first week I was using it from the hose popping off - but have had zero issues since I did that - if you get it I can send you my library for engraver power settings also - that was a lot of my time figuring out what to use on what
What you're experiencing is a very common issue. Many HVAC systems--including some brand-new systems--are not well designed to provide even airflow and temperature control throughout the house. There are various ways to remedy it, but none of them are really cheap or easy. One is to move the system to the attic, but that is a major project and can have many drawbacks, especially if the home is in an area that gets very cold in winter. Another is to change the ducting throughout the house. A third option is to have multiple zones, but again, that can be costly. You can also have a supplemental A/C system of some sort installed in the attic, which would help to cool the upstairs while leaving the existing system intact; but, again, that can cost a bit. So, be warned--there is no perfect, one-size-fits-all, inexpensive solution.
However, I will recommend something you can try, to possibly make things a little bit better, and that's to install register booster fans in the areas receiving less air flow. They do work, but it depends on a lot of factors, particularly the design of the home and the design of the HVAC system. In some homes, they virtually solve the problem. In other homes, they don't seem to have much effect at all. But, considering the minimal cost and effort involved in installing them, you might consider it worth a try. There are many types available, but here's just one I found quickly on Amazon, so you understand what I mean:
The master bedroom in my house was always 3-6 degrees warmer than the rest of my house. Replaced the AC and furnace shortly after moving in three years ago. The back of my houses faces due west and spikes to 76-80 degrees in the afternoon sun.
I bought this AC Infinity AIRTAP T4, Quiet Register Booster Fan for the master bedroom which has kept the temperature equal to or a few degrees cooler than the downstairs temps. Currently waiting on a second one to arrive. Could be worth a shot. I wasn’t convinced it would be a major help, but wanted to try something before picking up an expensive portable AC.
Been looking for inline fans to throw on that vent. Thought about building a box behind the ass end of the server rack to try and vent JUST the hot air coming out.
I was considering something like this, or potentially the next one up with the temperature sensor to automatically control the fan speed:
https://www.amazon.com/AC-Infinity-CLODLINE-S4-Controller/dp/B07JB292JC
Wanted something quiet.
I ordered this for our upstairs bedroom to help cool it down. AC Infinity AIRTAP T4, Quiet Register Booster Fan with Thermostat Control. Heating Cooling AC Vent. Fits 4” x 10” Register Holes. https://www.amazon.com/dp/B0792QR5YT/ref=cm_sw_r_cp_api_glt_fabc_301KKQ4X0E06EY92P6RD
However, when I unscrewed the ceiling vent/return I am not able to pull it out, the floor vents are easy to remove. What am I doing wrong or what do I need to remove the ceiling vent?
Same issue in my master bedroom on a south wall. Not sure what the actual problem is but I purchased 2 of these vents and my room is nice and cool. They pump up the airflow coming out of the vents and are fairly inexpensive (compared to potential thousands in insulation or other larger issues).
That’s on the table for sure. I have one from Lowe’s that’s helping but I’ve been thinking about upping the ante a bit.
Would something like this be reasonable or is this more of a indoor grow room sort of device?

Good to hear. It’s not worth it to cheap out on poor quality items.
Your parts list seems alright so far. Only things I would really change are:
Vivosun exhaust fan/filter….it gets a little noisy after a a few months of use. I own it and will be upgrading to AC Infinity once my budget allows.
Surpsun light….is only drawing 150 watts of power. Because of the fans inside of the light you’re actually only getting about 140 watts to the diodes. You’d be better off going after something with a little more power. I think Spider Farmer is probably the cheapest I would go on a light…this light linked doesn’t even have what is considered “enough” light for the 4x4.
Vivosun tents are okay. Mine has been pretty solid for three years. A few pinholes on the walls, but that could be from me being too rough on it.
Nutrients! Some come with ph buffers so you can just mix and feed without having to test PH.
Twist ties can be found on Amazon or at Home Depot.
I have one of these setups.
Here's my part list from my spring build. https://docs.google.com/spreadsheets/d/1Gpli0ImTdp8gyW8D0G-jJ_QKIiQNmJMolhFDQhx7Reg/htmlview
Lots of flexibility in this list for cost and types.
Since this grow I've bought an AC Infinity Cloudline T4 and moved the existing VIVOSON to the bottom of the outside of the tent and using it as an intake. Here's the new https://www.amazon.com/dp/B06ZXWN3BG?ref=ppx_pop_mob_ap_share
I tried to grow 3 plants initially... that was way to many even with meticulous LST and netting. Currently have 1 going and have a nice full healthy tent. Considering running two autos next run though.
Growing in coco and using remo nutrients, I water daily with 10% runoff in a 3gal cloth pot. Easy peazy.
Next thing that I would like to change here is the light. Love my Mars Hydro but this one doesn't have a variable controller and it would be nice to turn it down a tad while in veg. One of those things, it's fine but it could be better.
Good luck!
