too hot!!!

I got my temps down to 79.0 F just by leaving the door open and having a fan on the outside

Their back upto 84 but still better than 91

If you lack common sense maybe growing weed is not a great idea.

What the fuck does that mean? It's a simple question about my temps and I figured it out bymyself thanks. I don't lack commone sense you Fuckin retard, if you don't have,something positive to say then dont comment

Hey man I did the same thing my first grow. CFLs. In a closet. No ventilation. Series of fans and open doors. But it was winter

The thing that made the largest difference was having a dedicated fan blowing the heat off the lights and an open door. I also hung a box fan in the doorway all the way at the top facing out. The light fan blows the heat off the light, the heat rises naturally and then is expelled by the box fan. The only thing about all that is you're just recycling the same old hot stale air. Hey-it worked for me, but I worried about mold the entire time.

Good luck dude!

Hahaha that's funny man sounds pretty similar to what I got going on, i got a blizzard fan up top blowing air out another desk fan in there blowing air around and a fan on the outside to pusj fresh air in. Any chance you remember how many lights/ plants you had and how much you yielded?

An open door is dandy for cooling but you need your room sealed from light.
Your plants could hermi and the sights and smells could get you in trouble.

They will have complete darkness when the lights are off during flowering, but I figured it doesn't matter if the doors open when the lights are on 24 hours a day anyways

I am doing the same exact thing right now (open doors during the day, closed at night, fan 24/7. Difference is i still have ventilation at night because i have an exhaust. But i am in an attic, ambient temps dont go below 85 right now. Ughh and its not even july!!!!

I plan on putting an ac in, hope to get ambient temps down to 78-80 degrees. If that doesnt work Ill duct the AC all the way over to the grow room... so much for stealth lol.

I had 400 actual watts of CFL and two autoflower plants. Each one yielded roughly an ounce +/- a few grams. Most of the lights were in a DIY hood.

I had a lot of fun with it. Taught me a lot. Especially how important heat displacement would be in larger future grows. Since I got an exhaust to get rid of the hot air it's less problematic. Like I said it was in winter and the ambient indoor temperature was 62-65. I couldn't imagine trying the same thing in 75-78 like it is now.

Shit ay I'm planning on having 410 actual watts of CFL but I have five normal Feminized kings kush plants in my closet, and the one thing that works out for me is IRS just starting to get hot but I'm starting flowering on Monday so the lights will go off at 9am to keep it cool and go on at 9pm

Will temps go down when you turn the lights off during the flowering stage?

depends on season and other factors being in the attic heat from the whole house tends to rise and gather in the attics. An ac def helps. Venting in any closet is a pain in the ass especially once you get over 250 watts of most anything. Consider removing some cfl and using shop lights IE T5 even cheapo T8 work as well as cfl and produce half the heat. get the 2 or 4 footers and box in. Also if you want more dense buds with CFL I found adding the horti colored cfl helped a lot.

Ok thanks for the advice I knwo where I can get some t5's or t8's, what are horti colored cfls though?

If you're going to use a crap load of fluorescent bulbs and CFLs, a 400 watt would be quite a bit more efficient. It might also be easier to cool if you just get an air-cooled reflector and a high-output duct fan. In the summer time, and ideally any time you need some kind of venting!! That entails making a hole in the ceiling\wall, or making a door that allows venting or something. Heat needs to be removed.

Even just using an AC would be incredibly inefficient.

Ya but that requires a ballast and all that other shit you were talking abot which is,expensive, cfls are cheap to run easy to hang and can be put into normal light sockets

I will upgrade to bigger and better things once I know what I am doing and have a bit more space, for me im just doing it for fun and experience
