cooling down the room

if im using 2 90w ufo's to veg 20 kush clones will i still need my a/c or will fans do and what type of timers do u guys use.

depending on your grow space you may just need fans without the A/C.
you will need fans anyhows to move the air around them. keep em nice and fresh!
just keep an eye on the temps and hummidity.
As for timers, a 15 min plug timer from any electrical/hardware store will do the trick
Good Luck
