hey jakezking, thanks for stopping in :jointsmile:

for the lights... right whats in there is:

6x 23watt (1600 lumens @ 6500K) - these are the ones in the parabolic refelectors
4x 29watt (2200 lumens @ 2700K)

they are arranged that each plant is basically dedicated a 6500K bulb + a 2700K bulb and then there is 1 more 6500K bulb per 2 plants

I was planning to veg off the 6500Ks on their own, but then i started reading about people mixing it up a bit... i had the parts and the bulbs... so i figured i'd give it a try.

when i move onto flowering i'll be switching to 6x 29watt 2700K + 4x 42watt 2600 lumens @ 2700K bulbs

this has been working pretty well so far.. i keep the lights as close as i can, and this seems to be helping with keeping them bushy even though its a sativa dom hybrid... i haven;t measured but i'd say they are still under 6" in height and i can see the some leaf growth already that is the start of the 5th node.

edit: i totally forgot about the heat issues you mentioned lol... there certainly is some heat build up from the CFLs... i couldn;t compare it to a HPS because i've never used one... but considering from what i've read you need to keep an HPS about 20" away from the plants otherwise you'll burn them... well my heat problems seem pretty minor in comparison as my CFLs generally sit around the 2" away mark as best i can.

i do have a 5 or 6" industrial fan in the top and passive air intake at the bottom... i think i'll be adding a second fan to the roof though as I know heat is going to become a bigger problem in a month or 2
