temp

im having trouble keeping my temp down can any 1 help?the current temp is 89/90 is this bad?ive got a big office fan and a smaller fan blowing around my plants my grow rooms 4ftby 6 by 8 ft with 400w light and a 600w light with 13 plants in my windows open too

upgade your intanke fan and pull air in from thee window and if you can afford it get vented shields thats my 2 cents

i have no intake fan is that why im having problems?just 2 fans set at the far end of my grow blowing towards the window,this is my 1st grow so any info/tips would b nice cheers

An intake fan would probably help. That or get an ac

if the worst comes to the worst, ie if you can't put an intake fan up at the window or through your wall you could get yourself a small air conditioning unit, but ideally get an intake fan

change ur light cycle so that the plants are in darkness thru the daytime(when its hottest) and on at nite time. this is what i do during the summer.

dosney really matter in our country dura. freezing 24/7

Yes that is bad. Just blowing the air around does virtually nothing, you either need intake and exhaust plus circulation, or you go with a sealed room with air conditioning and co2 supplementation.

cheers guys,would it help if maybe i moved a fan to next to the window?as ive spent loads on equipment lights fans cutting ect thats my funds gone

also my leafs on a few plants started to curl upwards on the edges of the leafs any ideas what this could be is it to do with the temp? and on a few leafs started to yellow on one plant small blobs of yellow patches i think this maybe wer ive spilled feed on them but unsure

Dude, you can spend all the money in the world, but if your intake/exhaust volume and ratio's aren't right you will never have success. It's absolutely essential.
Edit: and no, just putting a fan near a window won't cut it, at all.
edit edit: yes, that leaf curl is most likely from heat stress. It's hard to say for sure without a picture, but with your stated temps I'd say yes.

not sure how big your setup is but a tent with a intake from your window and a outtake to your attic or another room would work but wouldnt help with smell.
the other way would be a tent witha scrubber pulling air from your tent to a attic or another room whil a intake pulls cool air into your tent and put it on a temp
control works great

I was having a heat problem as well, come to realize that my temp gauge was getting hotter because it was under the 1000w HPS light. I moved it on my aeroponics tubes below plants and temp went down 10 degrees, I was freezing my plants

lol... what do you want me to tell you that hasn't been already said.
