Hey
@Donald Gibbler welcome to AFN some great points made by
@Arthur
I personally think those yeilds are possible but not in a 9/10 week timeframe.
Most if not all of the heavy yeilding strains i know of take 12 weeks+
There are a fair few 1 pound auto grows documented here on AFN ( and even a legendary 1kilo auto grow) but they are few and far between.
Also if pure yeild is your goal there are much more efficient ways to acheive it.
1 pound under 1000w is under 1gram per watt. Your also putting all your eggs in one basket so to speak.
If you any issues with that 1 plant you miss your target.
My current grow is in roughly a 4x4 space running 4 plants in a hydro recirculated drip system under 240w of quantum board style lights.
I expect to harvest 25+oz thats about 1.5lb
Just food for thought my friend!
Anyway heres my personal list of high yeilding autoflowering qstrains.
Dutch passion
auto ultimate, auto extreme, mazar, blueberry
Dinafem
Cheese xxl ,white widow xxl ,bubba kush ,critical jack , blue cheese
Mephisto genetics
Hubbabubbasmelloscope , skywalker
There are just from my personal experience.
Whatever happens i would love to follow along in your adventure dude
