A more in depth CO2 question...

  1. Got everything I need or so I'd thought...anybody can weigh in on the need for an in-line CO2 heater?? I will have closed loop venting on my hoods(a 600W HPS and 400W MH) and a general FAE with a second blower on a humistatic controller. Hoping fuzzy logic manages to keep the injection time to a minimum. 10X10X8(with 3x6X8 closet) so about 950CF?? Is this heater a must?? Thanks

  2. The two most important factors when planning to use CO2 that I know of are light(lux) and temp.
