First I'd get really good at simply using 3 part Flora Series and CaliMagic (which is a good ratio of Ca:Mg). Then I'd seal the room and move to CO2. Then again I run my canopy at 100 to 105 all summer without CO2 so I'm probably giving you bad information.oh golly, i barely understand GH... LOL i have a lot to learn this week... gonna need a bunch of time to read this week
Carry on ;D
