The best yeild I have ever had of one plant was just over a lb that was about 4/5 year ago the strain was arjons ultra haze,but I would go with Hollands hope,or ams I have hit 10/12 most years of both if there not found or ripped,I did time wreck this year from tga and lost coast og ,the time wreck looked has though it was gonna be a heavy producer but was robbed so was the lost cost og.
I have run a few auto's and the best yeild wise I have done was in a polly tunnel and produced 2 oz per plant I did 10.There will be better auto growers out there I ain't a lover of them to be honest,I did get 1 1/2 oz from sensi seeds super skunk,but it would not advice any one buying them out of the 5 I ordered only 2 was feminized the others 100% males,robbed they was supposed to be stable femanized strain.the smoke was very nice though.
This year I am going all out auto's I have been working a lot this year with a auto grower who gets tidy amounts of the little guys,gonna try Jack herer,and cheese from greenhouse,and magnum from think it's big Buddha he is getting 6 oz dry from that strain.
