just got back to town. Was out working and i built a bigger room. instead of the 4x4 area that i was using before now i am going to be using a 4x8 room. They have really filled out my little 4x4 area real good. they are going to be happy in there new home. I think i am going to do a water change out before i have to leave again for the week. I think the co2 that i am using sure is shown a difference from my previous grows.
