How many of these will I need for a 4' x 4' grow tent?

2-4 would be safe depending on how far away from the plants they are. It's pretty bright.

If you want lighter poles a company called Bearpaw sells aluminum poles for 2.99 per 16" with inserts and 2.39 without. I dont know the exact length this tent needs but with a similar tent I needed 2 9ft poles I needed 12 with inserts and 2 without.http://www.bearpawwd.com/poles_stakes/poles_stakes.php#344

Depends on the size of the tank. Would recommend two fixtures of the 16" model for a 4 footer, and one fixtures of the 24" model for a 3 footer. Hope this helps!

You will need at least 2 for sure. I have a 30" tank and one just barely does it. If I had room for another one I would put acsecondbon the tank to get better light at the bottom.

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

a tent, or anywhere you put it, needs to be 54" (4'6") or more. hope that helps.

Although we are fairly new to the game, we are having good results with 2 of them down the center of a 5 X 9 Gorilla tent, so I guess that means that one should handle around 22.5 square feet. At present they are around 4 to 4 .5 feet from the floor and we raise them gradually as the plants grow. According the the previous responders, we are just a little on the conservative side. We really like these light kits.

I would use 6 if you are stacking a load on top to get into the show site. But if just rolling the crate with no extra you could get by with 4.

It all depends on how tall you want your plants and how big of a carbon filter. I'd say the tent is big enough for 3 plants at 3ft tall

For growing yes, but don't expect much flowering. I run 6 of them in a 4 by 4 room.

That depends on the size of the plant, if you're trying for "special" plants then up to 6 "sea of green" method, but if you want to grow a plant to full potential then 1-2 plants. Right now I have a single rosemary plant in it that's almost 4' tall and about 3' wide and soon to outgrow the tent, so it all depends on what/how/how long you grow.

these cover about 3.5' foot radius area at about 12 to 15 inches above plant with good growth, I eventually found they do great at 6-7 inches but coverage reduces to around 2-2.5 foot radius, most of the ufo styles have similar coverage , that will help you determine how many you will need. I think 2-4 lights will be good coverage ,,have had great growth and would definitely buy another

Do not use 4x4s unless your height is no more than 4 ft off the ground. a unit of this size will require support columns like a schedule 40 pipe 4 in in diameter or more embedded in 3 by 3 ft concrete footings at least.

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.

Not much. We have a large patio that would probably require 8 of them or so.

Each unit is four feet by four feet. Need 2-3 feet high of topsoil/potting soil. So 2 feet x 4x4 would be 32 cubic feet

My grow bed is 6" x 12" x 18", which is about a quarter of the volume as yours. I used 3/4ths of a bag, so I would expect yours to take about 3 of these bags.
