how many under each light.

If i grow my plants upto 2 feet(at the end of flower) can any suggest how many plants (at that height) could i put under the lamps to get maximum yeild.
I am using 600w hps x 3. and what formation would be best, ie: 1 2 3 or 1 2
........................................................................................................3
I also have a light rail which i can use, can i increase the amount i can put under the lights with the rail?? and if so, to what extent?

Depends on the pots size.
Heres how big each lights foot print is.

In my experience a 600 is good for 3x3 and a 1000w is 4x4. 6 to 9 plants per light = 1 sq ft per plant.

i am using 10lt pots.

Good to hear Woodsmaneh.

Hello Friend,

• Don't place too many plants, approx. (20 - 25 per m2)
• 600 W per m2.
• Aim for maximum of 1 gram of dried bud per watt of light.
• Most experienced Dutch growers achieve 0.75 gram - 0.83 gram per watt.
• At 0.83 g per watt, 600W = 500 grams (1.1lb) e.g. 25 plants x 20 gram per plant = 500 g.
• At 0.83 g per watt, 600W = 500 grams (1.1lb) e.g. 20 plants x 25 gram per plant = 500 g.
