i bought 2 single hose units and 1 duel from home depot, the single hose units i bought for 350 bucks each and i spent a few more dollars on duct tape and ducting so i could convert them into duel hose. the duel hose unit i bought is 300btu larger than my other 2 and it has a heater. it was 500...

looks good. i would sugest lining the roof and whater walls up there with a radiant barrior instead of white paint or mylar because it will insulate and help your heat signature so the f.l.a.r.e eyes in the sky dont see you glowing like a lighthouse. i bought mine at home depot for 50 bucks a...

regrets just made a great point. or a grow tent set up might work best for you.

their is no way to achieve you goals with out having a hole to let air out and a hole to let new air in. you will also need at least 1 good fan at one of those holes. i bought 2 50cfm bathroom exhaust fans for 12 buck a piece ( 75cfm for $22 also available) . i used them to cool a closet grow...

hang your light and mark where it goes and cut a 6inch round hole at each end off the light in the ceiling. run 3ft of 6in ducting from each end of light and into the ceiling. then go in your atic and attach a 6in inline fan so it blows into the light and back into attic.

you need to cool the light. if you dont a room at 70 will be over 100 in 15 min. and i believe everyone on this site with a 400 watt or larger light will tell you the same thing. you cant buy a better electric heat source than a hid grow light

i bought 1 duel hose and 2 single hose from home depot, the 2 single hose ones where about 350 bucks and i was able to convert them both into duel hose

jesus why dont you buy the 2" t5 from homedepot , for the money you spend on high output t5's you can get twice as many bulbs and fixtures. put most of them ontop of you grow and line your walls with them. they run real cool plants can touch bulbs and not burn. they come with 30k bulbs for...

how are you cooling the light? what kind of hood or shade do you have?

it shows the part number for 4 foot bulbs. 2 ft are 24 watts. im looking everywhere for 2ft 54 watt bulbs cant find them. call them and make sure before you buy. i believe the advertisement is misleading

i use 750 cfm for 1400 watts. fans push beter than they pull and you dont want to heat up fan with the hot air from light.

reread the spects on two foot t5 lights. i cant find 54 watt 2 foot lights only the 4 foot ones are 54 watt. i could be wrong let me know. it is beter to spead light around. more angles more leaves get light

put a desiel genator in the garage and vent garage. buy a desiel truck and a desiel fuel pump. go to gas station with desiel truck and fill up the tanks. park desiel truck in the garrage with the generator. siffen gas out of truck and put it in the generators tank with the electric fuel pump.

hi goatslayer. from what you posted i think you are going to be fine. the only change i would make is to the fan cooling your light. the light is the only real source of heat so if the cooler the light the cooler the room. the cooler the air cooling the light the cooler the room. so i would move...

home-depot and Lowe's sell 2" t5. they come in 2 bulb ballast strips with 2 30k bulbs for 25 bucks. they are not high output. i believe they are 18 watts a bulb. they are also cooler running than high output. i use them and the 4 foot versions. they are so cool running plants will grow and rap...

hi bob, the idea is to have some cross flow, air in low and from left, air out high to the right. understand the goal? and yes use 4 in ducting . you cant leave holes because the light will come out. if possible put fan in attic and run a duct to the grow area so you don't hear it. and remember...

thx bloodshot420

no bob, duel hose is exactly that 2 hoses one carrying air in from an outside source into ac unit's hot condenser, that air is then returned to the outside source through the second hose. the cooled air that you want comes out the top of ac unit itself. you want the unit in the grow room, you...

do you have a septic or public sewer? if you have a septic and you push to much air (cfm) down the drain you will fill you septic tank with air. the only exit for that air is through porous dirt in your septic field, up the vent on roof or out the drains in your house. the only reason no body's...

i'm not being negative, sorry if i sounded negative. i think a 8 inch fan forcing air down the toleit drain could pressurize the system and force water or what ever else is in the drain out with the air. the vent is for equalizing the air pressure in the line so that when you flush your toliet...
