Switching from MH to HPS

[drew225]

The red HPS lamp plus the photo-period change to 12/12 are what triggers the change to flower. So yes start hps with 12/12.
Yes a 1000 is big enough for 12 plants as long as they fit in a 6x6 foot square. A 1000 hps has a foot print of 8x8 feet.
it gets weak to the outside edge.

Remember your canapy can only b abut 2 feet deep. The lights don't penetrate any more than that.
KBS is how the big boy's play if ou want to google it. freaken trees.

KBS??

Thats what I was afraid of on the canopy. Sounds like im going to have to figure out how to top them. They are all over a foot right now and I just switched to 12/12. Would it be advisable to maybe put some cfl lights on both sides so the lower part of the plants get light? They are all fit in an about an 8X4 1/2. Thanks for the info!!
