How many plants in my 4X4 tray, and break down of light coverage

I have a 4X4 tray = equals 2304 in. total area

I plan to give each plant 5X5 inch nest pots in an ebb and flow = 25 in

2304/25= 92 plants

Is this possible?

Also I am thinking of a 1000 HPS for each 4X4 tray, could possibly I just use 2 1000 HPS for three 4X4 trays in a line if they are doubled centered at each 1/3?
Would love some incite!

92 plants is doable. prob no veg or very very short. 1 1k will be fine over a single 4x4 tray. 2 1k over 3 4x4 is good. but it will give you 42 watts per square foot. you should atleast have 50 watts per sq foot. in my opinion 1 would do 3 1k over a 4x8 tray. or 2 1k over a 3x6. why not do smaller amount of plants and grow em bigger?

2000watts for 4x4 is a waste of money. Your gains will be negligible with double the heat problems. For a 4x4, I'd go with 16 plants and a 1000 HPS. You should be pumpin' out 2lbs if you know your stuff.

2lbs? in ONE 4x4 tray?? what kind of numbers could you pull with a 600 instead of a 1000?

Anywhere between 16-22 ounces, depending on the strain.

that's good to hear. im waiting to run my 1000w over a 4x4 tray. also running co2. hope i see those numbers!!

Keep in mind that 1 gram per watt is about as good as you'll ever do. So 1000watts can yield 1000 grams and 600watts can yield 600 grams. This is strain-dependent though so even with everything dialed in, you still may never hit that benchmark. But if you come close, pat yourself on the back!

woord. +rep breww

...I'm doing 2 4x4 trays with one 1000 watt on a light mover..something to think about.
