This round I am growing two plants (A-Train X NL) of unknown gender in identical containers. I have a single air pump split in two with just a weighted air tube (no airstone). The container holds about 2 liters. Seeds were germed in peat pucks and placed directly into 2" net pots as soon as the sprouts appeared. I used pipe insulating foam cut in half to get a tighter fit with the peat pucks. Water is tap at 300 PPM no nutes. Lighting is a warm white LED spotlight pulling 3.4 watts mounted in my infamous bucket lamp. Here is Hazel at the end of the first day: I will attempt to update weekly.
