howdy Kush. re the af x af = af................... that's what I am hoping. shouldn't be a problem with 100% autoflowering regular seed, but I am still fairly inexperienced with autos. I considered going for several different regulars but opted for Dr.F in the end and have already pollinated 3 other famous autos with the Dr.F males in the hope that back-crossing (at least 3x) will give me reg seed stock of the famous feminised only strains.
re soil not being a high yielder; youre probably right but its not really a concern for me as I always have more than I need and its only for personal. I water when they need it.
party on Kush.
