400 Watt Metal Halide for sure and with young plants run em in a cooled hood works great.

MH or T5??? so heres what i got...... im a few days away from my first harvest. after that i have to stop growing because i am moving. however, once i move im going to immediately start growing again. i vegged with a dick ton of CFL's and flowered with a 400 watt HPS. i just recently read somewhere that those CFL's loose their luminosity after a month or two...so that sucks. those are out so in my new set up im planning on having 2 rooms, 1 veg 1 flower. each maybe 3x3 or 4x4 at best Rating: 5
