Can you put this unit under a grow light?
1267247
Absolutely! Once the seedlings begin to emerge, switch on the grow light so they won't have to elongate looking for light. (No need to turn the light on before that, since they're under the soil and unaffected by it.) Once the seedlings begin to hit the lid on the seedling tray, remove the lid, but leave everything under the grow light until you have enough true leaves to transplant the seedlings into bigger pots or into the ground. (Remember that you'll have to occasionally water them because there will no longer be any condensation keeping them moist.)

I've been using a grow light for seed starting for years. I used a make-shift grow light with this Hydrofarm unit and had good success. The key to successful seed starting if mildly warm bottom heat and constant minimum moisture to the growing medium. Don't overwater.

I recommend it. I also sue 2 of these AcuRite 00613A1 Indoor Humidity Monitor one inside and one outside. The light may be just what you need to raise the temperature in your baby's greenhouse. in a warm room I almost cooked my seedlings as the temp went up to 93f before I caught it but an a cooler room (68f) it kept the temp about 11 degrees warmer than the ambient temp in the room

Yes I suppose you could, but I only use the lid until the seeds sprout then they are in the open air.

Yes! My plant is not near a window and it only receives light from a lamp. No issues at all and looks very healthy.

You can use it, but without a reflector such as: Hydrofarm FLCDG125D Fluorowing Compact Fluorescent System (bulb that comes with the hood is for vegetative stage, colder blue spectrum) much of the light will not be directed towards the tomato plants. Use the warm bulb for the flower and fruiting stages. Found this lamp to be of some use for supplemental fill in areas not well lit by the primary light source. Serious (small 4'x4' up to 6'x6') greenhouse vegetable growers are better off with: http://www.htgsupply.com/Product-Digital-Greenhouse-%20600w-HPS-Grow-Light ,use the standard 92,000 lumens bulb that comes with it for flowering and purchase the GrowBright 600w MH Conversion Bulb (72,000 lumens) ($44.00) for vegetative growth.

I don't know about that. Mine is above ground and I put plants all around it to disguise. Works great!

I think you can get away with one light to germinate seeds before planting outside. I grow veggies in a tent inside and one does a great job in a 3x3 Mylar tent. The light is very bright for it's 90 watt rating.

As far as I know you can. You may want to get a stand for the light so that way it's not sitting directly in the top of tank or whatever you are using.

Medium low yes, medium high no. The Java Fern, Anubias, Java Moss should all thrive under LED lighting. If you had a bunch of Amazon Swords you'd have to use the Finnex models instead. Three out of four of their models put out a lot more light, Planted+, Ray2 and Monster Ray. It's about the same light as Finnex's outdated FugeRay line.

Yes, one of the better options for doing so. For vegetative growth I recommend you have full spectrum or "blue" spectrum bulbs. 5400 Kelvin? That's from memory. If that's off the answers are a Google search away

It should have no problem with that, if its just for the lights, pulling from the grow room might make it hot by the 4th light, depending on grow room size, if your doing a other fan/s for that should work fine

I don't think I'll do what you want it to. I use mine to start seedlings (peppers, lettuce, zucchini) and keep the light about a foot or two above lants. From that distance it only throws enough light to fill the area for about a 2' in diameter. You MIGHT be able to grow one or two pepper plants but not tomatoes (my opinion). You'll be better suited with something like 4' t-5 lighting fixture. I use the t-5 fixture to help a miniature orange tree (about the same size as a full grown tomato plant) during the short days of our northern winters

No. This light is only good for low light plants. Get a finnex planted plus for your swords.

Not really. The good thing though, is you can zap it in one spot and then move it. I put a plastic sandwich bag over the lighting unit to keep it clean.

Well, the 4 lights give out twice as much light and enable you to grow plants on a deeper shelf. I really like this light, and last year my seedlings grew better under these lamps than under my 2 light lamps. I didn't find them to put out too much heat, but they do give some warmth, which is good. I made an L-shape growing area with 2 sets of shelves. I put up 2 four-feet lamps on several shelves, and this lamp on the shorter side.

No. This is supplemental lighting for decorative purposes only. You should use a proper light.

Yes. Especially not having windows with bright light during the winter, the grow light helped our bonsai thrive and sprout new leaves. If your bonsai is too large to fit directly under the light, placing it right next to the light and periodically turning it will still help.

Can this be used outdoors in a mostly enclosed (bottom is slightly open) post fixture?

Not really. I'm little disapointed. The light is not enough power to ensure grow plants.
