Just germinated - Getting high temps. Help!

High all, just had 100% germination with 5 jacky whites and 5 g-bomb and got them vegging under a 600w.

Here is the problem, I'm getting readings of 29-32 degrees with around 40% humidity on two different hydrometers.

I've got the inlet duct pointing right out of the window and the air coming in is cool, and now put the seedlings near the inlet inside the tent.

Setup is as follows:

1m2 by 2m budbox
600w metal halide for veg and hps for flower (digital ballast)
150mm ruck exhaust with filter
125mm ruck intake (both with acoustic ducting)
6" clip on fan

Any tips on reducing the temps a bit? Checked the extraction/fans and there doesn't seem to be anything wrong there, so I'm a bit stumped and don't want to damage/kill the seedlings so early



Jacky White


G-bomb


Any suggestions?

Bump for quick response. I think one has just died

Go to the shop and get a big bag of ice then put it in your grow room, it's a very very very temporary fix.

It probably is the ventilation man, you'll probably need more intake!

do what arid said for the emergency. then, think about getting a couple of cfl;s for your seedlings instead of the 600. that's a lot more light than they need at this stage and is boosting your temps.

Yeah, just bit the bullet, ran out and got a 125 CFL. Temps have dropped to 26, so I'm happy
