Weed 4 JennyB

Well this week was awesome! I solved a problem and made another even worse one. Realizing that my nighttime temperatures were dropping too low and my humidity would drop to 20% seemingly no matter what I did, I decided to be super smart and add an aquarium tank heater to my hydroponics reservoir. The thought being that a warm tank of water would act as a temperature as well as humidity buffer. It worked great! Overnight temps rose to 18C or so and humidity rose to 40% and stayed. Initial growth was super fast, and then stalled out. Ph had risen to 6.5 and I had knocked it down but now it was up to 8!!! Even after recalibrating my ph pen. The aquarium tank heater actually gave off visible light and my tank tho only a week old was completely brown slime. Ughh.
