If you're prone to overwatering, try Rain Science bags, You should be perfect! LOL!I'm a new grower and I have failed twice now lol. I've been trying to grow in a greenhouse, and it got way to hot outside and shocked them, plus I over watered. The biggest issue for me is learning how to water.
I THINK I have proper watering down correctly with them............at the end of this grow! LOL! I've tended to under water these bags.
Since I'm organic and I top amend nutes, I water from above heavily, but not fully. I do this a little before lights out. At the beginning of the light cycle, I give the same feed, but in the tray. I stop adding water when it's not taken up after 10 min.
Also, get some sort of surfactant to help you water better and more even. And speaking of even, one tip I seldom see given, get yourself a pump spray rig to water and feed your girls, if you don't already have one.
RAW Yucca is a good surfactant that you can easily find. I now use ThermX70. Very cost effective, a little goes a long way.
