Just go LED.

I went LED and I will never look back. The amount of cash I saved on blown bulbs, elaborate extraction and cooling is enough incentive.

I have 4 plants growing in a 90cm x 90cm tent right now. I have to water every 4 - 5 days maybe more. I can water my plants and all I have to check is the plants heights.

There is no issue with heat, heat signatures, helicopters with thermal cameras etc etc. I water less and so I don't use as much fertiliser, The LEDs use just 1/3 of the HID systems.

I have had great results from my LED light. I even had some of the branches of my Big Bud x Northern Light break under the weight of the buds my LED produced.

I might have a small set-up but I get good yields. I filled 6 x 2 litre jard with weed from just 2 plants last grow. I have 4 plants this grow

LED is the way to go dude... Check out the 2 links in my signature for the proof..
silent leprechaun Reviewed by silent leprechaun on . help me cool my grow room So a few years ago I had a grow room set up with 2 1kw lights, and 1 400 watt light, in a 10 x 10 bedroom. That was my first grow ever and I never got to the harvest cuz I ended up in the hospital for 3 days and by the time I got back my plants were all dead. When I had that grow room, I powered each 1kw light with a 6" 465cfm inline fan, that was venting into the bedroom next to it. It was a passive intake and I didn't bother to hook up the other end of the ventilation system from the Rating: 5
