they look fine
stop looking 4 every little change in the plants with the thought - shit there is a problem - u'll wreck ya nervs :D
i grow plants in veg. on 24 h of light, when something go wrong they need some time to react
how much hours of light r u giving them 24, 18/6 ?
i don't really see yellow
give em time to react - it's pretty hard to over water them at this stage
don't give em any nutes 4 now

They;re on 18/6 but i noticed this morning the temps were getting up to about 93. so i'm kicking the idea around of putting an exhaust fan in the ceiling or building a box...

93 is def too hot man! Get em down to 75-80 deg.! Asap!

at 95 deg theyll die. at 85 without extra c02 theyll slow or stop growing completely.

I've been noticing a slow down for sure. what kind of exhaust fan would be good to draw out that heat? I don't think a computer fan's going to do the trick for this one. it might be too small.

Google how to measure cubic feet....I know inline centrifugal fans work great. You will know what size fan you need after you determine your cubic feet of the room.

well
i make my ventilation before growing plants :D
air can really fuck thigs up - believe it, the circulating air helps a lot in the heat
make sure u have fresh air circulating, and exhaust to take air out of the room - AIR circulation is very very immportant
don't grow weed without it :bigjoint:

I thought I'd be in the clear since I had an oscilating fan pointing down to move the air as well as 2 6" fans on the plants themselves plus I open the doors about 10 times a night to let fresh air in...wonder if it would be better to build a box and move them or put up a venting fan? how effective do you guys think the exhaust fan would be? enough to drop the temp from 93-80 atleast??

It depends on a lot of things. Temperature outdoors? Size of exhaust fan? Size of exhaust tubing? Size of room? An exhaust fan is mandatory! Exactly how effective it will be for you, is in the details. It damn sure couldn't hurt! Carefully consider your intake & exhaust. You want FRESH air if possible. Don't forget to stick some panty hose over the end so you don't suck up half the bugs in your yard.

I think i'll end up building a box. I think if I have a decent box that can intake cool air from the ac I'll be better in the long run. Atleast so the air won't be so stuffy and able to cool down faster....it's winter here in florida but you can't tell, it's still in the 80's. can you use a 150w HID in a 4tx4wx2d box without it over heating you think. I should probably research when i get home.

Right on. Well I already got the wood I need for the box so now I'll just be building it whenever I get home. I'll post some pics tonight so you people can give me some pointers.
