(3) Feminized GG4 + (1) 9 LB Hammer

Week 3 almost killed the plants with a water change where I removed the plants, placed them in a res together, had the air pump turned up too much and beat the roots to death. Thankfully with the purchase of a chiller, rapid new root growth saved the plants. I am now holding steady at 68 degrees F and I no longer remove the plants during changes. They're actually so thirst that just topping off each week does a good flush. I will take root photos soon.
