how much space you have and how much your light can cover
The 25 plants together cover an area of 5 X 5 .... The light pretty much covers that area but I will have to rotate my girls every once in a while ...

My only goal is to maximize yield and I read somewhere on this board that taller does not mean more yield cause the top of the plant absorbs all lumens leaving almost nothing for the bottom ???????

Please help.

Iâ??m just wondering how tall the plants should get before I turn the light to a 12/12 cycle! I do not want to veg for too long for no reason and still want to maximize my yield. You can see how tall they are right now with the picture with a normal compact disc in front â?¦ Should I flower them now or wait a little longer ???? Thanks for you help, 9KtuFK Rating: 5
