Let's Say I Wanted to Try CO2...

[Steveo McNello]

I have the tank [got it for free] and the regulator with tubing. Now I have to build my reactor and I should be good. Still trying to find a drop checker though.

i do think co2 makes it easier. if you can contoll co2 and lighting more accurately, then the only real variable is ferts. if your pretty new to this then you may want to take a look at ei dosing(estimative index)you dont need to be a chemist to use ei.
