Lots of little experiments in between
Worst grow was afghani - its a trooper, takes a beating well, but during harvest the buds were smaller than what I'm used to. Which is misleading because the veg growth is crazy. Considering I treid Afghani later in my grow experience I concluded its not for me. Those free seeds go to the trash.
Pineapple chunk got really good feedback from everyone I shared with. Probably the best feedback.
I can't comment on yield comparisons because my methods have changed and there are too many variables but the white widow auto flowers knocked my dick in the dirt. They were pretty potent and they were everyone's favorite next to pineapple chunk. And that was my 2nd grow when I was being a fuck up and not exchanging my 5 gallon DWC buckets and just topping off nutes from start to finish, wet trimming, and drying at 30% humidity for 3 days. Nevertheless everyone loved the white widow auto. Not a fan of auto flower yields though. Sorry if there is disagreement but I have not seen it. But I totally agree that if you cram a lot of those autos together I am sure the added yield of a SOG would overcome any reduced yield of an autoflower. But seeds are expensive. I think a lot of noobs (myself included) start out with auto flowers as our first grow because we hear that they are a good place to start. We suck as growers at first and then attribute the result to the autos. Maybe thats a false correlation. I'm going to grow them again and do it right for a valid, variable free, side by side comparison. I'm going to take an ounce of the auto and an ounce of the regular and make shatter so I can compare shatter yields to get a fairly decent potency comparison.
