Sounds good thanks for your taking time in responding. Am going to start fresh from seeds inside. I have a large carbon filter,in-line fan, allfans on floor of tent,all hooked up through a cool tube light ducting out of the tent out the window. Four 12inch fans attached to the bars in tent two oscillating on floor,a cool mist humidifier,but the room is so warm I hope air conditioner will work to bring the temp down from 90.I seen a lot of these 5x5 tents they can really produce some nice plants.im looking to get a few great ladies that have a high medicine effect for my ms.
I'm hoping someone else will chime in on this, but I'm not sure about your "cool mist humidifier." Humidity isn't a plant's friend, and it can lead to all sorts of mold and other problems, not to mention if it's misting onto the plants then your lights can burn the plants (magnifying glass effect).
The plant should be able to get all the water it needs from the soil--barring some crisis--some you might be overthinking it with this humidifier. You'll want low humidity. Indoors, I run a dehumidifier... which is the exact opposite of yours. One puts water in the air and one takes it out. Four 12 inch fans might be adding to your heat (a very little). I'm stumped on your heat issue. Got any pictures? Something isn't right in the set up. If you're still having heat issues.
Here's one thought I'm having.
1) Are you 100 percent certain that you have the fan venting out the tent instead of pushing the air back into the tent? Sounds silly, but you should check that out. Go to the exhaust duct and put your hand to it. You should feel a lot of air pushing against your hand. If it's sucking in, then that might be the problem right there.
2) You didn't mention where or how the cool air is getting into the tent. Do you have a vent or two open on the bottom of the tent?
3) Is your exhaust on the floor of the tent? It should be higher up, pulling the hot air out.
You should totally take like ten pictures so I can understand what's going on here. You got a new tent, and a cooltube, so you shouldn't be having these problems. Let's figure it out. Others will chime in once you've got some pics up.
