Ventilation for veg/clone chamber in grow cab

[The Fonz]

My 600W is an HPS. Isn't it better to use a white or blue type of light such as a CFL or MH?

Better, yes, but some folks grow all the way through using just an HPS light. If I have one to spare, I throw it on vegging plants too (along with some blue CFLs), and while the HPS light isn't optimal for veg, it still helps some. I've got 10 clones growing under eight blue CFLs plus a 400w HPS light at the moment, and they appreciate the extra lumens, even if it's redder than they need at the moment.

Sounds interesting. I was going to put up some cfl's in the flower area to give extra light during the flower stage. Guess I could move the plants up there for the last week of veg and get things going once more below.

Yep, blue spectrum is optimal, but the 6x23W's aren't going to compare to the 600W HPS no matter what light spectrum they are. I do it all the time.

Hey Fona,BlueBear,Jamstigator
I found this place to buy fans and things,it's called {www.SURPLUSCENTER.com}.
I got two 3"x3"x1" AC axis fans for air cirulation ,they are 25cfm's and queit too.They have been running now nonstop for 10weeks and only costed me $7.95 each.I ordered a 200cfm muffin fan for the light in a cab I'am building,the fan only costs $16.95 too.When it gets here I'll post on how well it works.It only has to move air about 4'feet through the light and out of the cab.I'll post more on that later.
Peace
