I switched last week to an 18/6 light cycle. I got the molasses from my buddy who owns an organic (RoT organics) shop in Texas. For best microbial growth, he recommended 4 oz per gallon of water. I stopped using it though after doing further research and discovering that it's more important to the plant during the flowering phase. I also did some research and heard some things that lead me to the conclusion that over-watering, in a lot of cases, refers more to frequency than amount of water. With that being said, I started drenching my plants and watering every 2-3 days. My com-padre put a lot of fucking sand (Which I'm told blocks oxygen?? Can anyone confirm or deny?) in the soil so it drains super fast...
I plan on throwing together my own soil mix without sand the next time around, and switching to 5GAL square pales to use my space more efficiently.
