Good grow lights don't have to be expensive. I use this one and my lemon tree is very healthy and happy, and in full bloom right now. I have it on a timer for when it no longer gets direct morning sun until evening (11-8). Your lemon looks more like a nutrient deficiency, or maybe even a chemical burn.
There are certain beneficial organisms that allegedly prey on/parasitize gnat larva. I tried some Steinernema feltiae (microscopic nematode) purchased from Nature's Good Guys and watered with those in there. Seemed to work reasonably well for the time being, but this is just anecdotal.
Maybe someone with more experience can chime in on the use of these sorts of lil guys.

6-3-3 is not a very good fertilizer, although you shouldn't be fertilizing in the winter anyway. You need something high in nitrogen, like blood meal, and during blooming you will want high phosphorous. I would supplement during the winter with liquid seaweed with added iron (like this: https://www.amazon.com/Maxicrop-1-Liter-Seaweed-Plus-Iron/dp/B0001YC468 ) and when spring comes I would look for something like Jack's citrus feed, which has a lot of micronutrients.
If you find mites, you are in for a battle. I wrote another post about mites and some other folks chimed in in the comments, and you may find that helpful:
This is the one I bought: SANSI 36W Daylight LED Plant Light Bulb Full Spectrum Ceramic LED Grow Light Blub, E26 Plant Bulb Sunlight White Grow Light for Indoor Garden Farming Greenhouse Grow Walls, UV IR E26 https://www.amazon.com/dp/B07BRKG7X1/ref=cm_sw_r_cp_api_fabt1_YI6TFbD3CCHZR?_encoding=UTF8&psc=1
I use this one. It fits into a regular bulb socket and it isn't purple. It's like a regular light, only brighter. But not too bright to sit next to it in a living room.
https://www.amazon.com/dp/B07NP1H25N?ref=ppx_pop_mob_ap_share
The average PPFD for the Sansi 15w is 111.56 μmol/s/m² based on 19.7” above plants. Flowering plants need 800 to 1k μmol/s/m². So you’re giving that plant about one tenth of the light it needs to flower. I see you have some natural light coming in, but if it’s fall/winter where you are, it’s not enough light for long enough to help very much.
Google “recommended ppfd for flowering” - that will help you understand what you need instead.
I like this HLG light but $150 is a lot.
The first link you posted is insanely overpriced for what it is. The second link, while the fixture looks nice...I can guarantee it’s also a rip off. It doesn’t list any details of spectrum (it just claims full spectrum) and no actual wattage output. You might be able to sustain a tree for a few months if you left that light on almost 18 hours a day. But in reality the energy costs might not be worth it in the long run.
You are putting yourself behind the 8 ball in a way, as any true grow light that can actually grow a citrus (which requires 6-8 hours of sunlight...the strongest light nobody can recreate) is always going to be a bit “industrial” looking and not meant to hang in a catalog living room advertisement. If I were in your position, I’d suggest finding a different spot for your citrus where it’s more reasonable to purchase a better quality light within the budget of the couple links you’re posting (I’m guessing between $70-100?).
Otherwise if changing location isn’t an option, then I’d recommend putting a few higher quality grow spectrum bulbs in some lights you already own around your tree and seeing if you can sustain your tree over a few months. Most bulbs output around 50 watts, which is what I’m guessing most of the fixtures you posted would advertise. And it would be much cheaper.
Edit: just to kind of give you an idea...this older Mars Hydro is very highly reviewed as a wonderful entry-point into grow lights. Great price, output and color spectrum. Honestly in order to grow and sustain a healthy citrus tree indoors, you’ll need something in this direction. Amazon Link
Oh yeah I am about to start preventative spraying when I water because I have lost too many plants to mites. I am getting one of these because my current lamp with grow lights is too short for a 7 foot tree. Do you think using a foliar spray would accomplish the same thing? TBH mixing it all sounds like a PITA!
Ah ok I will remove it. I got these. I will stop misting tap water, but I thought that was only an issue with poor tap water and well water. I am in NYC which usually has excellent water.
I was sort of looking at something like:
I'm not sure if its overkill for me though, and I"ll have to see how much it costs once I figure out what else I need to buy for it...
​
Pesticides is a good thought! I'm in Canada and I've read that we can't get neem oil here, but I want to do some digging. I don't have anything at the house, so I'll look into that and the soap and copper fungicide! Hopefully I can get all in Canada.
Thank you for the suggestions!
Be careful about getting excited for buds growing. It could also mean that the plant is desperate to reproduce cus it's dying. They'll focus their energy on reproduction when not getting enough of what it needs.

I got this and mine are making new leaves indoors rn. It's 50% rn. Get at it.
spider mites. Safers end all is my go to. spray everything including the bottom of the leaves once a week till they are gone. Doing a neem oil soil drench at the same time will really send them the message. 1/4 cup cold pressed neem oil to two gallons of warm water with a squirt of mild dish soap. Mix it really well to emulsify the oil into the water and then drench the soil well. Make sure the neem oil you use contains Azadirachtin. Something like this. Hope that helps they are a big pain in the ass.
I have this light on it
It was by the window for additional light but far too much wind was coming in to keep it there
Sun burn. Spray a product to protect the leaves, something like this:
You may want to look into something that’s full spectrum. Those purple lights are okay for seedlings and clones but not so great for mature plants. Something like this would probably be your best bet.

I'm in South Florida. So bugs are a constant enemy. This is awesome for insects! I mainly use it for meyer lemon and key limes.
Spider mites. :-( I've found that using neem oil as recommended on the bottle helped me knock them out. Alternatively, insecticidal soaps can help clear up the infestation. I'm in Canada and utilized the Safer's End All spray to clear up mine.
You'll want to isolate this from any other indoor plants you have, as the little buggers spread like mad if you give them the chance.
Good luck!
I use one of these in 7b and keep my meyer lemon in the garage through the winter and outside over 50 Fahrenheit. I have probably 50-75 buds with several open flowers right now that I am hand pollenating with a q-tip. My tree is about 3 years old and I fertilize with Down To Earth citrus fertilizer

Okay yeah having mites before you pretty much have to treat for quite a while. If you had them on that one tree you pretty much can guarantee a few of them made it on to your others. That could be the source of your drop as well.

https://www.amazon.com/gp/product/B00PF6QFB2/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
Then I use 1 part perlite and 1 part regular potting soil.
Well it was a little bit of an experiment. Its these. Which are similar to Grow Oya which I've heard good things from on some of the gardening youtube channels I follow, but Grow Oya has been sold out for a while. The idea is to be more efficient with water, less evaporation and less maintenance. I also thought that since citrus don't like to sit in damp soil that this would moderate the water they receive and keep the soil a little bit on the drier side.
I've gone back and forth on whether to use them or not because the top part of the soil doesnt really get moist so its harder to tell if they need watered or not. Which is why I've been using a wooden stick to check soil moisture. In reality I think im going to stick with traditional watering and use these for when Im out of town.
Ya, I mean I bought this Sansi for my indoor Wash Navel to see how it does. Reviews said it only pulled about 50W, which is close to what I'm showing at 49W. I live in Colorado so I'm trying to come up with reasonable indoor solutions that don't make my home look like a science experiment because I have 3 citrus that will be spending about half of their yearly life indoors. I thought about a Mars Hydro, but again the aesthetics of those type of lights just isn't ideal.
I’m a total novice, fwiw, and have been reading about this myself. Going to try a Mars hydro sp150 based on a bunch of research so far.
As best I can tell from research, citrus trees are similar to marijuana in their light needs…basically the more the better (assuming they’re accustomed to it).
It seems like the “ideal” setup would be one of those weed-focused grow lights inside a grow tent. Specifically I’ve read that a Mars hydro SP3000 inside a 2x4ft grow tent would be a great setup for a few small trees or a couple medium ones.
My Meyer is very new, so I’m gonna try their smaller sp150 on a wire wardrobe rack turned into a plant stand and see how it goes.

But I was just reading a thread earlier and wonder if it isn’t enough.
I'd say it definitely won't be.
I used this on my 4ft Meyer Lemon last winter, and it dropped every leaf:
I think it might be lying about its wattage equivalency tho
This year I bought two Quantum Boards from Horticulture Lighting Group, supposedly the best quality grow lights you can buy. 300W each. I'm adding them to my mix, but I've also added two more trees
OK, I'll back off the water a bit. I've long hated not knowing if I am over or under watering. Just ordered this gizmo which hopefully will sort me out going forward:

My attempt at making my setup not quite so ugly. I had clip on lights on poles before.

I use this iron
Ferti-Lome Chelated Liquid Iron and Other Micro Nutrients
I use plain old epsom salt for magnesium amendment
And I use leftover coffee and grounds to keep ph low so the plants can uptake nutrients
It didn't bloom but I only recently swapped to these lights halfway through the winter. It is about 1 metre away from a Southwest window and gets lots of indirect light too.
Please help me revive my favorite plant! Here are the details.
The symptoms
- The tree drops several leaves a day. It still flowers and fruits consistently, but most of the new fruit shrivels; only a few keep growing.
- Some of the lower branches have completely died off.
- In January–February it had an infestation of <em>labia minor</em> earwigs, so I let it dry out for a few weeks; they disappeared and I resumed watering about a month ago.
The setup
- Lemon tree I bought in the NYC flower district March 15 2020.
- After a few months I repotted it in the planter shown here. The planter is way too big, but it has a ~12" Bloem Ups-A-Daisy filler insert about halfway down. Under that is just air (I hope). It drains well.
- The soil is mostly cactus mix with some added sand and perlite. I have fertilized it about 3 times over the year, most recently about 2 weeks ago, with about a cup of Jobe's All Purpose 4-4-4 granules. I can still smell the most recent addition :/
- The grow light stays on from dawn to 2 hours after sunset. The humidifier runs about 3 hours a day.
- I water it once a week, giving it a good soak from the top with 1–1.5 liters of tap water.
Thank you so much!
This one has my 6' tall lime tree very happy, 8 feet from the nearest window. It is BRIGHT if you look directly at it. https://www.amazon.com/dp/B07PLHGFPB/ref=cm_sw_r_cp_apa_fabc_XCTBYZ1V3NBWWSBANV5R?_encoding=UTF8&psc=1
I've also been very happy with this GE bulb for my 3' tall lemon. They also have 4' long light bars in the same line which are good for groups of smaller plants on a shelf, and seed starting. https://www.amazon.com/dp/B07NNT3G7J/ref=cm_sw_r_cp_apa_fabc_BTJZ6QEKHHZ179NEH92C
Congrats! Keep doing what you’re doing if it’s healthy.
The science still supports my statement, unfortunately.
I have 8 grow lights, which were purchased as I learned more about light and how plants use it and how that light is measured. (I didn’t know any of that stuff when I started.)
Included in my 8 grow lights is the exact light you linked to. I have it on my low light plants because it’s simply not enough for anything else, even at a distance of 6”.
This is my best (and most recent) purchase: HLG 100 Grow Light for Veg and Bloom - at $150, it’s a lot, but I kept having to replace my plants that were dying due to lack of light (or getting bugs because they were stressed by lack of light).
There are better lights, and probably better deals, but this one fit my budget and my lighting needs.
I assume OP is in my spot - genuinely wants their plants to thrive; not sure how to make that happen or how to get that information. I don’t want to advise them to spend $30 or $40 on a grow light I know can’t do the job for them.
Ok so I made one. If you get a greenhouse kit you can insulate the walls. Then run a cable to it. On the outlet put a temp switch (for example this one). You can program what temperatures it kicks on at. Put in some little heaters and some incandescent Christmas lights (not LED).
It'll only heat the greenhouse/hothouse when below the set temp and will kick off when not needed.
Not OP, but my dwarf meyer lemon tree has been doing well under this: https://www.amazon.com/dp/B07NY6XW7Z/ref=cm_sw_r_cp_apap_UWFTKf5sCvneC
It's currently in a 5 gallon pot and it's top leaves are about 6" from the light, which is on for almost 12h every day.
I really like this one, and my tree loves it. It's a pleasant level of light that isn't purple and it fits in a standard light fixture. I have it in my living room on a timer and you wouldn't know it's a grow light when it's on. Just a little brighter to the eye. My tree has flower buds all over it right now and the foliage is healthy. https://www.amazon.com/dp/B07NP1H25N/ref=cm_sw_r_cp_apa_fabc_G2m2FbKVEQY1J?_encoding=UTF8&psc=1
Hi everyone,
I have a few citrus trees in my house moved inside for the winter. I’ve been keeping grow lights on them for 8-12 hours a day. I have about 4 of these lights hanging maybe 1-2 feet above the trees. The trees get no direct sunlight.
They are in the same room as where I work and the lights are pretty bright so the 8-12 hours is broken up and it’s not consistent throughout the day.
The room is about 60-80 degrees but usually hovers at about 68-70 and the soil temps look like they’re at 65. The soil is the 5-1-1 soil mixture.
The trees seem to be struggling but haven’t had mass leaf drop. The leaves get droopy like in the pictures. I haven’t watered 2/3 in the photo in over a week and don’t want to risk overwatering them. It just seems like a slow decline for them.
Are my lights too powerful? What could be causing their health to deteriorate?
I started a key lime tree from seed (currently about a foot tall and growing like crazy) under one of these which are $55. I've also grown hot peppers under it.

This is a great grow light. It fits into a regular bulb socket and is a natural looking light. Not too bright and not off-color for a regular living space. I use it for my tree indoors.
Real grow lights, ones that actually are good and will improve your plant's health, ones that aren't chinese fake knock-off trying-to-scam-you lights....are pricey. There is an extensive science to grow lights. At the very least need to look for lights that are: LED, full spectrium, and can reach 660nanometers. If a light for sale doesn't tell you this information then don't trust it. Any legit light will be public about its abilities. This Vipar one has been tried and proven (like scientifically with light meters) to be legit over on the 420blazeit subreddits. But that light only gives light in a 2x2ft area just as a heads up (and if you are in the flowering stage it only goes 1.5x1.5ft). People always over estimate how much range grow lights give. Yes there will be light cast outside of the range but it will be useless for the plant. So measure your plant and any future growth you expect or future plant siblings if you need a smaller grow light vs a larger one.
This is why so many fake-o chinese sellers try to swoop in with cheap shitty lights since people run away from the larger price tag. Even regular T5's that grannies use to start veggies indoors will run $100+ (I personally don't like them because they use more power and they get sooo hot. And you need to have one bulb that's 6500kelvin and another 2500kelvin to get 'full spectrum').
From the pictures I would suspect the pot does not have good drainage. Probably over the years the roots blocked the drainage holes. So I suggest first, gently remove the pot and check the roots for any signs of rot. When checking also smell the substrate, over watered substrate has a very distinct marshy smell.
If it is that, you need to repot the plant, doing some root pruning. When you prune the roots, you will need to also do some light pruning of the branches, just to keep both balanced. After this, you can not fertilize the pot for about a month, to give time for the roots to heal (remember fertilizers are salts).
On the meanwhile you can fertilize leaves, by spraying them with a very diluted fertilizer mixture. I recommend you buying something like this that has all the nutrients, and use half the dose they recommend, but spray the plant with twice the frequency.
Pic 3: you have woolly scale https://en.wikipedia.org/wiki/Scale_insect Neem oil is ineffective against them as the oil can't coat their body to suffocate them unlike armored scales which are totally smooth.
You will need to use something with imidacloprid to really get them. Like this https://www.amazon.com/BioAdanced-Science-Based-Solutions-Vegetable-Concentrate/dp/B004BLNVMS/ but you can also check your local garden center and read the ingredients of what they have.
How big was the plant's root ball when you put it into this pot? Repotting should be like a Russian nesting doll, only 1 size up. At most, only 1 inch extra of space between the root ball and the edge of the new pot. Any larger and water held in the empty space can't wick away causing any new roots attempting to grow into the new space to rot. Which them causes more rot inwards.
>or whenever the soil feels dry to the touch.
How far down in the soil is it dry? Sometimes it's better to stick a wooden skewer down through the root ball and let it sit for an hour. When you pull it out the skewer will either be the same pale color or darkened and wet from moisture. If it's wet, don't water. Overwatering can kill. Underwatering will make the leaves curl up a bit at which point you're like "yea let's water you and then a 6 hrs later the plants leaves are back to normal".
>I live in Zone 6b, southeastern PA.
Is this plant living outside or inside right now? Being so young the root ball might be dropping too low in temperature coupled with the moist soil.
Also where did you get a chinotto plant I recently had italian chinotto soda and it was effing delicious.
Imidacloprid is not banned in NY as of yet I believe
https://www.nysenate.gov/legislation/bills/2019/s1074
as in there is a bill in progress to ban it but it's not actually banned from my understanding. There might be some other bill which did pass that banned Ready-to-Use concentrations (stupid people use this without reading directions and go overboard. At least with concentrated stuff there's a lot more steps so people who really need it actually read and follow directions).
Anyway, that means you can buy the concentrated insecticide on online (honestly it's pretty much sold out in any state in-stores due to end-of-season) and have it delivered and you using it no problem.

Sorry, 24w, here's Amazon link SANSI 24W LED Plant Light Bulb Full Spectrum LED Grow Light Plant Lights for Indoor Plants, E26 Grow Light https://www.amazon.com/dp/B07BRKT56T/ref=cm_sw_r_cp_apa_i_dCvxDbJZ2G661
Sure, it was this spray https://www.amazon.com/gp/product/B00A51Y8ZM/, I will occasionally add in a tsp of fish fertilizer per gallon. It's a 13.5-gallon pot. And I got the tree in 2018, it was basically a small sapling at that point. It clearly had some deficiency because within a week of foliar feeding it began producing new leaves and flowered prodigiously.
I have two of these. Have them on a timer; they work great (though the cooling fans are a bit loud). I grow oranges, limes, lemons, avocados, figs and banana, and they all seem to love them.
And LED full spectrum lights are available these days for cheap and don't use much power to run. I plan on getting one of these https://www.amazon.ca/gp/product/B07PJ4VWF7 so I can put them in and control the temperature a bit better over the winter for my guys.
That certainly looks like spider mites. I had to deal with a pretty heavy spider mite infestation and it required a lot of persistence. As a first step I'd suggest spraying the tree down with a strong stream of water from a hose to try to knock as many mites off as possible. Next I'd follow up with castille soap like Dr. Bronner's (make sure it's a soap made from fatty acids and not glycerin-based) mixed at a ratio of 1.5oz/gallon. The mites have a life cycle of a just a couple of days so it's important to spray every day to stay on top of things. My infestation was much worse than yours and I was able to eliminate them within 2 weeks with daily spraying. Good luck!
Got four 1-2 year old trees. Heights are 1-2 ft with canopy diameter about 1-1.5ft. What kind of glow light should I buy? I have a north east facing window which I plan to keep the plants on. Should I keep them there and rotate them to distribute sunlight ? And the supplement with glow light on the other side? So 2x2 formation but bias the light on the 2 trees at the back? And will this light do for all four of them as supplemental light? I live in Zone 9b. https://www.amazon.com/MARS-HYDRO-Spectrum-Hydroponic-Greenhouse/dp/B07VL8FZS1/ref=mp_s_a_1_2_sspa?dchild=1&keywords=full+spectrum+grow+light+led&qid=1600659111&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzS045N0lNTEJTVE...
https://www.amazon.com/dp/B07BRKT56T/ref=cm_sw_r_cp_apa_i_NNuxFbNS9H4MC this is what I use for my trees I bring inside. Used it for two years now, trees are perfectly happy. I have it plugged into a floor lamp with adjustable arms. You can tell it's not a regular bulb but is not screaming that it's a grow light in any way.
This is what I use. Be sure not to fertilize two weeks before and two weeks after.
I’m a huge fan of Intermatic timers which run about $15 each. I’ve tried others and these are just the right kind of basic: easy to use and they don’t just stop working for no reason.
You’ll definitely need 14 to 16 hours of light, not 8.
A lot of people just put their plant as close to a southern facing window (if you're in the north hemisphere) without grow lights. They can 'survive' winter months this way but they often go dormant and lose a bunch of leaves and bounce back next spring. If you want to avoid this, you probably want some lights, and you'll need to go pretty heavy to have any effect: https://www.amazon.com/MARS-HYDRO-Spectrum-Hydroponic-Greenhouse/dp/B07VL8FZS1/ This one seems to be pretty good and I almost bought it once, it might even be able to support a full citrus tree year-round indoors. I recommend a timer, you'll need 8 hours a day. You could even get the bigger 1000-watt one if you were so inclined.
>It gets direct sun from like 3-6pm, so it has some natural light.
I notice it's developing a lemon rather nicely, so if you've had that plant in the location for half a year or more, then it seems pretty happy. However, if it's a new plant (or was newly moved to that location), additional supplemental lighting could be beneficial.
>I was looking at like 150-300 W bulbs because I had no clue. I was also looking at the blurple ones because I also had no clue
150W Bulbs are definitely overkill unless they're incandescent, and most of the energy from those bulbs radiates out as heat. I personally prefer full spectrum LEDs because I don't want the inside of my house to look like a nightclub (blurple is hard on the eyes) and LEDs are more energy efficient, outputting more light and less heat.
>Does the housing you put the bulb in matter? Do you just use one of those cheap metal ones from Home Depot?
Keep in mind that since you already have a red/blue spectrum grow lamp in that picture in addition to the window, so if you want more supplemental lighting, you probably don't need to go the full 36W that I linked earlier. The <strong>24W</strong> version is probably sufficient. It's a pretty big bulb, so just make sure you find a housing that is big enough to fit it and is compatible both with its E26 Socket and its Wattage. I know some folks who use <strong>this sort of thing</strong> with it, and home depot probably offers something similar.

I keep three small Meyer lemons under it indoors in the winter and they show new growth and flowers under the light.
