Thank you for the kind comments. Yes, just switched to Co2 a few days ago and to the EI fert system. Was using Excel and Flourish over the three weeks of growth but I did have a great chance to discuss with Tom Barr my system and he suggested I read all I could about Co2 (as I was apprehensive) and make the leap. Goodness..I am glad I did.
Using pressurized co2 is a quick learning curve. Once you do it the apprehension everyone seems to have before hand disappears.
