Is anyone using this 4-bulb fixture over four 10" x 20" trays of seedlings. Trying to decide between 4 bulb and 6 bulb. Would like to save the money

The 4 x 4 light system will be sufficient to start (4) 10x20 trays indoors before eventually planting outside.

I know it is late but maybe will help someone else. If you just plan on germination and a short stay under light may want to go with a 4 bulb T8 will use only about 60% of the power. If you plan on them being under them much longer then a couple weeks then you need the extra light. I personally use 6 bulb T8 for germination over a 2' x 4' tray (4 1020s) which is about 24w per sq ft. Then for growth, which is any point past a month, 8 bulb T5 for 55w per sq ft. Keep the lights close to prevent stretch.

If you are concerned about light coverage, raise the light upwards to expand the light area. A small rise in the lights will not destroy any heat advantage.

Hi! I purchased the 4 bulb fixture last winter. I had at least 6 trays of seedlings under the lights and they all popped up beautifully! Every couple of days I rotated the trays which helped. I,too, was trying to be frugal. Don't think you'll be disappointed. Good luck!

This one will suffice to that. I'd just recommend that you switch the bulbs to these ones in order to obtain that better light output and quality. Hope it helps! (Pack of 6) F54T5/865/HO 54-Watt T5 High Output 6500K Daylight Bulbs

You can select a 2700K bulb for this fixture when you check out. Although I haven't used this particular light for that purpose, I'm sure the 2700K bulb would do great for the growth and flowering stages.

Yea for sure I'm using one light fixture on my 90 gallon tall tank which has a similar footprint with a 40 gallon breeder. 36 inch long 18 inch wide and 32 inches tall. The light is plenty strong make sure you hang it a east 12 inches from top of the water to get good light dispersal for a three foot tank. Also takes some careful aqua scaping so you don't get any shadows on the side. Mine looks like a volcano very high in the middle and slopes down on both sides so as not creating casting almost any shadows. I run it at almost 80-90 percent and eveif I ran two I would probably not have aqua scales this way but I like the look and my coral in the bottom sandbed are getting enough light. I get ton of coralline algae on the sides of the tank so I am pretty confident the light is spreading enough. I don't have a gazillion corals so I did not see the need for more than one light and having one now I can definitely see that I can surely add more in the future without any problems. I am even having luck with sps corals so this is the real deal! You will definitely not be able to run them up that high intensity since the breeder is so much more of a shallow tank but that's good because you will be saving on electricity, also another reason I ran one light... Make sure you a climate your corals from very little light these lights are super powerful!

It all depends on how many your looking to grow and from what stage of growth. This light is perfect for seedlings, clones and small plants. It covers a 2*3 area, just remember that cfls need to be close to the plants to produce vigorous growth. I found that 6-10inches above the plants is the sweet spot for this light.. You can fit 6 decent size plants under it but its better for a tray of clones or seedlings....

It really depens on how ong it will be before you can water the plants again. I use one large for each pot and some of the pots are 12" wide. If I was going for more then 4 days then I use 2 bulbs. We live in NM with little rain.

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

My husband bought regular shop light fixtures and had exchange them because the reptile bulb size is "T8" and a regular fluorescent fixture is a "T10" I believe. He got the T8 fixture in Lowes. We also found out that if there is not 2 bulbs in the unit a single light won't light up. I hope that helps!

Hello Cathy, Thank you for asking! Typically, in an 8" pot we recommend 6 bulbs, you can certainly go smaller if you wish. So, in a 4" i would put 3 or 4. http://www.easytogrowbulbs.com/g-18-oxalis-planting-guide-regnelli-triangularis-others-from-bulbs.aspx Copy this link to see our growing guide as well. They are super easy and take almost no water to get started! Let me know if I can assist further. Best Wishes,Dena GrangeEasy to Grow Bulbs

If you get 3, you could grow your plants throughout the entire life cycle. I just did it with my plants, but be warned, the bulb may not last long. Mine didn't but the plants did grow great under it.

On the 36" each bulb is rated at 39 watts. So the 4 bulb fixture is a total of 156 watts. Dont get to hung up on watts per gallon per say. It does matter, but look into PAR more importantly. With my 36" I have no problem growing anything. (SPS, LPS, etc...)

Hello there! This LED panel is designed specifically for flowering growth. Both this model and our High Output models are great for any plant growth, we just recommend you using a model best suited towards the spectrum of light you need (HO - vegetative/cloning and UV - flowering). The area that this light will cover depends on the size of the fixture and how high you mount it. If you mount this panel three feet high, it will cover 8.75 square feet and if you mount 6 feet high, it will cover roughly 15.75 square feet. This LED light is 16800 lumens.

The fixture is fine because you can double it up if necessary. The bulb selection will be a bit trickier. I use mine for plants with 10k bulbs and it works adequately.

The heat they put out is so minimal, plants can nearly touch the bulbs and not be cooked. I have both two bulb units and one of these. This one is BY FAR my favorite. Most of my seedlings are in flats. Using the two bulb units, with the flat turned lengthwise under the lights . . .the plants on both long edges for about two rows on each side for a total of four long rows . . .the seedlings become slightly more leggy than those seedlings closer to the middle. The reason why is the distance from the lights. Using the four bulb unit, all the seedlings get the same amount of light.

Anthony, I'm a bit slow on installing these, I bought 8 fixtures last year and another 2 recently. T8 fixtures are supposed to work well in low temperatures (20 F) so I'm trusting the liturature I read and what I've heard from coworkers enought to buy 10 of these fixtures. Sorry I don't yet have first hand experience.

That is what I used the light for. I bought 2, 1 for each light needed. Just read up on the turtle you have so you can buy appropriate bulbs. Also found the shorter bulbs (lower wattage) fit better regarding dome clearance & siting s\flat when bulb is in.

Well, this is my first time with a light(2'x4 bulb) and I'm only using it for seedlings. I would assume you could get some results with lettuce. I'd certainly try . I grow both Tuscan and curly leaf(Vates) kale in the garden and they're good size plants. You'd need big pots and a second light I think

fixture takes 3 bulbs each 100 watt max. I only have 75s and lighting is sufficient over kitchen table but there is recessed lighting also over my cooking area.
