i'm running a 600w light in my room 1.2mx2m and the temp is 83-85* ...

i have a second light (600w) but when its on the temp is a steady 96*..

i have air cooled lights 2 duct fans one sucking air from the hallway.. and the other pulling air through a carbon filter yhrough the lights and out to the hallway...

i have tried everything to drop the temp and can olny think that making the air thats sucked in to come from an a/c unit..

has any one done this ..

does it work..

Do it all the time. I currently use a 20k BTU window unit with a box built on the back. I vent the back of the A/C through a 8" vortex inline fan and then outside. Works wonders! My next step is to just use an actual split system.

if ur using duct booster and not a high cfm fan that could be a problem too but no as long as the ac doesnt drop the room temp to really low then it wont hurt the plants

Ac is fine for the plants. Mid 70's are a good temp to shoot for if you can.

sweet........... i will go out and buy one tomoro...

i think thats the answer to all my problems.........

I don't think the duct boosters work as good as they should.

A/C is a crop saver in summer, buy yourself a $60 thermostat and set it to the 70's and your good.

i think your question has been answered but do u have central a/c? if you have good fans i would think that would be good enuf to pull your 70-72 degree air into your grow room

i don't have cental a/c uk doesn't warent it (shame).. i've looked on ebay and think the freestanding ones you put water and ice in should do the job there £50 if not the decent ones are £200+...

now i know it won't hurt my girls i'll be staight into experimenting...
