is getting an air conditioner the best way to deal with heat issues, if so am gonna buy one
i agree it depends on your setup. the cheap and most efficient way is to have air cooled hood and exhaust them away from the grow room. this removes the heat directly from the source and works great so long as your ambient temps are in the right ranges. say your room is 85-90 with the light off then yeah i would get an ac. if it is more like 65-75 with the lights off and when the light goes on it get in the upper 90s then you only need to cool the source of the heat. also a inline fan will be much cheaper to run than an ac.it depends on your grow system i have a closet grow and and need an ac
no air cooled reflector, light is 600w hps, exhausting heat out of slightly opened window 1 desktop oscillating fan and 1 large oscillating fan, dont have fresh air intake, the air intake comes from in the bedroom, i have tried switching the bathroom fan round to bring fresh air from outside but that didnt work,do you have an air cooled reflector? what size is your light? where are you exhausting the heat to? do you have any circulating fans? do you have a fresh air intake?
nice one you just answered my next question about shade vs tubewhats the cfm on the 4 inch? you could try it, just buy the coolshade but you might need the reducers for the ducting, it might work, ive got a 5 inch 180 cfm on one of my 400 and it work great, also i would go with the coolshade thats got the flat glass rather than the rounded cooltubes.
i am searching ebay for a cool shade now,thought i could find a cheap one, but they are all dearer than my local hydro shop,lol ,so will prob get one from there as i have it as soon as pay for it, whats a good price for a cool shade, have found one for £55coolshades make a huge difference! trust me! your lights off temps are not high even if the room heats up 8 degrees with coolshade your still golden, with the decent fan all the heat from bulb is sucked out of room, so the room wont heat up much!
i prob will go 6 in exhaust, but as robsterb said might as well try the 4 inch one as i already have thatgo 6 inch!
get a xtrasun 6 its a inexpensive quality hood and air tight for better cooling($85
next get a valuline 6 inch centrifugal fan ($100
an eco fan 16 in wall mouneted fan for circulation ($30
and then 6 inch ducting (15+ depending on what quality you want
