ds90 and 600watts

anyone know if you can put a 600watt hps/mh in a 90x90x180cm tent with out burning the house down or would it be better off with a 400watt light in there

ill have forced air induction and cf filter extraction and a 6or8 inch fan just a bit of an update ordered a cool shade to go with this now so i should be ok for heat

If you have a good reflector/hood and a good fan there should be no issue with heat. 400cfm+ for a fan

I Have a 400w in a dr90 and temps at canopy are around 75f I am using around a 200cfm fan. A 400cfm should do the trick

i only got a 380cfm extraction and 280cfm intake will that still be ok ?

you should be good, depends on how good your hood is also.

its similar to this cooltube

you should be just fine

You could make either work (with an air cooled hood and good inline fan). I run a 600w in a 2'x4'x7' (61x121x213cm) tent around the same size... To be honest though, I would probably prefer a 400w instead with a couple of 2' T5 strip lights attached to both sides of the hood if I were to do it over again though.
