It's 2x2s and grow film. That's around $50. You can get a fan and filter combo on amazon for $150. Like this...

I used to do this with a house with a mother in laws suite. It had a closet that was rigged for a stacked washer and dryer. I used a fan similar to the fan in this kit to pull the heat out of the room. Honestly I don't think I'd care too much about the heat. My lab is in the garage in Austin, TX. The fans run a little loud but it works fine. It's been running well for a few years now.

Or you could just attach a duct that vents the air outside. There are also resins that are low-VOC. Anycubic sells Eco Resin made from soybean oil that claims to have "no VOC" and "no harmful chemicals". I'd probably try that and if it still smells then go for the air duct solution.

The hyperlink goes to the tent instead of the chilled logic LEDs. I know which ones you're talking about, but the link is bad. If you're running in a small tent you can really get by with a small fan. You could check out a 4in kit from Amazon. It's cheaper than your current filter and comes with a fan and some ducting. That would be more than enough for your little tent. If you haven't chosen your seeds yet, I would recommend Mephisto genetics for autos. Great stuff, quick shipping. If you're in Canada they do have their shop closed for a few weeks but you can order from the US or UK store.

You could always buy a carbon filter and fan kit and then just install the filter on the outside of your box, obviously making sure to set the fan as an exhaust.

Fan and Filter if your going to spend money on a smoke eater dont fuck around with over priced under powered consumer toys, a set up like this can clear a room in a few minutes the activated carbon in the filter can be easily changed without having to replace a brand specific filter cartage.

Found this kit on amazon: https://www.amazon.ca/VIVOSUN-Inline-Controller-Ducting-Ventilation/dp/B06XFRNPR8/ref=mp_s_a_1_5?crid=2JZC6WKBNDW8M&keywords=carbon%2Bfilter&qid=1554421615&s=gateway&sprefix=carbon%2B&sr=8-5&th=1&psc=1

I think it will do fine... Are there any cheaper kit alternatives?

The kit I was looking at, I am 80% sure my exhaust fan is trash

No, they were new. This was 2 years ago with a chinese company new to amazon so they were priced super low. I got the fan + controller + filter all for $45.

At the beginning of 2018 I replaced everything and pieced them together to save a little bit. Here are the numbers from Amazon:

Vivosun 4 inch 203 CFM inline fan with variable controller - $49.95

Amagabelli 4 inch carbon filter - $33.99

iPower 4 inch 8 feet air ducting - $7.99

Total: $91.93

Edit: Vivosun 4 inch kit for $89.99 is now available.

Honestly just look around on amazon for a bit. Any 4 inch carbon filter and inline fan combo should do just fine. If you wanna be lazy just buy this one then https://www.amazon.com/VIVOSUN-Inline-Controller-Carbon-Ducting/dp/B06XFRNPR8/ref=sr_1_15?ie=UTF8&qid=1511221397&sr=8-15&keywords=carbon+filter+4+inch

But honestly, any will do just fine.

I'm currently in the same position and have been looking at two different solutions.

Inline fans like this: https://www.amazon.com/gp/product/B06XFRNPR8 . The carbon filter will trap smoke and grease and the duct is long enough to reach the window. Filter is not washable, has to be replaced when full. (I would hang it from the ceiling).

There are also bench top fume extractors like this https://www.digikey.com/product-detail/en/jonard-tools/SA-9-115/K416-ND/186951 . At ~125 CFM, it should move enough air to filter air from the stove top. Replaceable filters too.

Careful of cheaper bench top fume extractor models - they have shallow working distances (< 6") and don't move enough air.

Yes I have this inline in my 3x3

My humidity with it on low is at 50 without soil or plants and my humidifier on max

I think it does, I see a little dial on the amazon listing. I only need the 4" because I only plan on growing 1 small auto that only grows to around 3ft max.

I would strongly recommend venting. The fume smell is just awful for some resins, and it lingers. You can print a mod to exhaust into a duct, and buy a vent fan to ensure there's negative pressure in the printer to exhaust the fumes outside.

I live in winnipeg, and print in -40c weather by attaching flexible ducting to a dryer vent framed in construction foam. The construction form is cut to fit my window, and I just pop it in when I want to print. If you want, I can put together an amazon shopping list with all of the DIY equipment.

But if that doesn't work for you, there are kits you can buy that are for for "other" uses, but fit perfectly for printing! Simply attach the duct mod to the 4" ducting in the kit, and it will filter it out!

The fan I have at hand is a basic 4in fan by vivosun says 203cfm https://www.amazon.com/VIVOSUN-Air-Filtration-Kit-Controller/dp/B06XFRNPR8?ref_=ast_sto_dp

I am about to go with that , would you say that it is going to perform better than this https://www.amazon.com/VIVOSUN-Air-Filtration-Kit-Controller/dp/B06XFRNPR8/ref=pd_lpo_sbs_86_t_0?_encoding=UTF8&amp;psc=1&amp;refRID=J69MSM35Y5V8WBQ6GCC9 ?
