Just a quick question ladies and gentlemen. Bottomline is I need more light for my space. I need at least a 400watt HPS for my area. I already have a 250 watt HPS. My question is which is going to cause more heat in my room...1 400 watt or 2 250 watt bulbs. I can keep the remote ballasts outside of my grow area. I'm not sure because I haven't had a 400 watter yet, so I'm not sure about the heat they produce, but a 250 watter raises my temps 10 degrees. Any suggestions from growers who have used 250 and 400 watters greatly appreciated.
