Thanks guys, I think I'll go with both then.

For the moment I've just got a computerfan that's producing some air movement inside the cabinet. I don't have a fresh air input but the plants are small, the cabinet is temporary and I produce some co2 from time to time in the glass bottle so I guess it's allright.

If I leave the HPS I'll have to have a cold air fan blowing on the plants though cause it's really producing an incredible amount of heat, more than I thought it would.

Again thanks for the advise
Kurt Mac Grower Reviewed by Kurt Mac Grower on . Is it too early for HPS? Hey guys, I decided to try out my HPS and installed it in my cabinet. The thing is that my plants aren't even two weeks old so I'm thinking it might be too early or something for such a strong light. So do you guys think I should put the crappy cfl tube back in for a while until they're a bit bigger or just leave the HPS? Thanks Rating: 5
