Hello Hello!
OK so I'm a greenhouse grower who has just bought two CFL's and I want to build a little cab for them!
The bulbs are both 105w (actual not equivalent), one is 2700k the other 6400k and I want to use both simultaneously.
Do I need intake and outake? Will a clip on fan do with the door open a bit?
Hmmm...any advice would be much appreciated...no building has started yet!
Thanks
put them both,the strain will consume that whats need,but sure for veg you need more 6500K.for example if you use 6 bulbs 4 of them is good to be 6500K but 3x6500K and 3x5000K is also ok.
imagine that my first first strain was made under 2700K only.....
Just completed the flower box but I am having temperature problems!
I am using 2x 120mm fans for exhaust and 1 x 120mm fan for intake and the temps are still too high! Since I added the intake fan the temp has cooled down from 100.4f to 87f. I have 16x 26w cfls in the box. Does anyone have any suggestions of cooling it down further?
