light light light light light, fill it. ventilation isn't a problem if you have cool tube lights and an air conditioner/heater and a air purifier with a good co2 enrichment system. go big or go home and you'll find you'll get great results with ensured efficiency:rasta:
robgolden Reviewed by robgolden on . 1000w HPS vs. 2 400w HPS For the time being, I'm borrowing a 1000w HPS setup, I have a 5X10 growroom, with 8 foot cieling, I was thinking 2 400s can use my space better, I'll be growing 15-18 plants at a time, all on 12/12 light cycle. Am I thinking right here? Thanks :thumbsup: Rating: 5
