Started four White Widow seeds and two Gorilla Glue seeds, picking the best one from each strain after a week. Started the seeds in a paper towel, and once they started sprouting I threw them in rockwool. At the end of the week, each strain selection was healthy enough to move out of the seedling tray and into the net pots.
For this grow I'm using Coleman 33-Quart Party Stackers with lids drilled/sawed to accommodate a 3" net pot and two 1/4" air tubes. I'm hoping this will both allow a large space for root growth, and keep the water cool and insulated.
