I've grown them 'fast' strains and 'super' auto's as Flash seeds callem... I did a
C-99xBB fast version that was pretty and harvested mid Sept..
Those 'Super Autos' are monsters... But what they are is just a auto flower that they were able to increase the veg time.. Mine took 120 days.. Sure I could've grown a reg photo plant to harvest within the same time frame. But what's nice is you can figure a harvest date with them I shot for a Sept 1st harvest and I got like 2 pounds off it.. It was 11' foot tall come harvest,,,, called Muay Thai I'd hate to see what she'd have been planted straight into a good soil
