You will be better off with a 150w or 250W hps in a cooltube. My 250w hps adds 1.5 degrees over room temp in the cab described above. The HPS puts out way more light than CFLS watt for watt. You would need about (15) 42w CFLs to equal (1) 250w hps. |
I have done a few test runs to see how hot it gets in there with all the lights running it get to be 101F but about 5 min after turning on the fans it cools right off to 80 and it will go lower but its quick thats for sure!! by X-mas I will be puting in a 90cfm this is just to get me started!!
I wish I could go with a HPS I hope by next yr to have one and with a cool tube would be sweet!!
I was hoping some of those light experts could tell me if that is enough light for my little room??
I will aslo be adding a 1'x1' screen just not sure how far above the plants it will need to be!! I guess it depends on the plant??
