Breeding Autos

I am just setting up this grow, including the tent and everything. From scratch more or less. I know the cold is gonna be an issue where it's at because it's only 10° C during the day. So I lined the area with 2" rigid insulation, got a little heat tube in there, heavy blanket overtop the tent and with the light on it got up to 21.5° overnight at ground level. Should be enough I hope. My plan is to take these critical mass x cbd auto fems and breed enough seeds to take advantage of the outdoor season here next year. Photo period plants often dont finish well in the PNW cause it gets too wet for big buds in the last few weeks of flower. So hopefully I can time these autos to finish maybe mid- late august when theres no less humidity and no rain.
