hi guys
im looking at running a 600watt hps for flowering
currently running 2x mars sp250 in 1.5 x 1.5 x 1.8 loft tent and i can keep my temps pretty stable using 100mm intake and exhaust but looking for a little more oomph for later flowering stages.
my question is what is the better of the fittings?
aircooled hood or tube? (100-150mm) for 600 watt bulb
cheers
