I am in in the process of setting up a 30 gal breeder (30" Long x 18" Wide x 12" High) as a planted tank. On all my other planted tanks, I have been using PC bulbs but I wanted to try a new lighting setup and it seems that T5HO are high recommended. I am building a hood and trying to determine how many T5HO bulbs w/ reflectors would be adequate for this setup assuming pressurized CO2 & dry ferts. Would 2 be enough? 3? 4? and compared to PC bulbs, how much heat do T5HO put off?
