Now im not gonna lie.... This is only my 3rd grow and I have 8 in veg under a 400w Mh, 2 guarantee'd 2 females, (Clones), the others are unknow bagseeds. Will be changing light regimen and spectrum to 13/11 under 1000w Hps. In a about 3 weeeks. My first grow was a loss, and my 2nd grow was micro. This grow i have space and great lighting.

From what I understand the more light the more the yield. I wouldnt go more than 10 plants under 2 1000w ers or light might not get to all areas of the plant. If there is any way you can add additional lights CFL or tube Floros for the walls, It would greatly bennefit your yield.


Take a look at this thread lots of good lighting info and how to calculate your yields based on lumens.

Good luck and I hope this thread helps: http://boards.cannabis.com/indoor-li...uch-light.html :thumbsup:
