High,

I've got a project with 7 lowryder no.2's in a 60cmx120cm, 200cm tall growroom, I'll be using one 200w envirolite(white spectrum) until flowering starts, then add another one with red spectrum, use these until harvest.
My question is, as these envirolites shouldn't produce much heat, will I be needing intake and exhaust? There would be one or two fans blowing towards the lamps and Co2 will be given with these: No Mercy Supply .

I'll be turning the lights off for one hour each day so they shouldn't produce excess heat.

Thanks:jointsmile:
