each light covers a 2x3 area perfect so 4 is the min and 6 is perfect for a 4x8 tent.

Okay cool I been placing then for 2x3 so i can change that to 3x3 cool. I right now have 12 of them and will have 24 in 4 weeks to do my whole grow area. which means I will have even better par so I am gonna keep them adjusted for 2x3 which means bigger yield I hope. Or am i wrong? I have been wrong before and will again I am sure.

His is like mine, my Nanolux 315 has a hood with the bulb mounted vertical.

The vert hoods have square coverage is all. You might have a little more of a rectangular foot print like 2x3 with those horizontals. Either way, your going to have plenty of light with that many in a room at those foot prints.
What footprint are you giving each plant?

I had a delay on my second vert hood. Seller cancelled my first order, it said "customer cancelled"...I thought maybe I screwed up. Ordered again, few days later, cancelled...out of stock. Douche.
Got one on the way now and found a $25 better deal @ $140.

More square footage will always yield more if light is available. Biggest factor for yield is usable lit space.

Yeah, why not change it to 3x3, and if you feel it's lacking you could add the rest. That'd save you 8 lights (planned 24 lights per 6 SF is 144sf, 144sf / 9 is 16 lamps). Lotta cash savings in equipment and electricity. Like BK said, 3x3 is proven.

Hey, I got a basic question for you guys.
Do you guys maintain a 315 at roughly 20" from canopy height, or are there points during the plant cycle you keep it a little higher? Like at flip, do you keep it at 20" and keep ratcheting it up, or keep it a little high and let it grow into the space?

I read the SS vertical reflector achieves max par at 16” and 2.5’ x 2.5’ area.
I run young plants about 2 feet-30” and mature plants at 18” unless the plant wants more. Some show no stress at the 16”.

24"+ in veg(seedlings,clones 4x4 area) 18" in flower(3x3 canopy)
For the most part,it's all on how the plants a growing(pheno depending) some like more,some like less.

6 plants, soil mix, 5&7gal smartpots, FoxFarms and Organic roots combo nutes, blue dream and Chocolate Mint under a single 315w LEC.... Flip time!! 
Please tell me how you got these? I have tried to work with EBM lighting and they are horrible to work with! They only take wire transfer and that does not insure me.
I am trying to buy 20 of these ballast, 40 bulbs, 20 hangers. They are insanel hard to deal with direct as days go by in between emails and once I asked for PayPal they totally quit responding.
