I have no idea about the genetics or how well they grow but I do know Super cropping and topping or defoliating a autoflower is just taking days of good healthy growth and turning the few numbered days a auto has into recovering from stress and trauma....Let a auto grow into its full potential by focusing on the basics, Temp, humidity, PH and watering/feeding and just let them be...I let my Iranians just grow wild last summer and got a 1 pounder dry weight followed by a close 1 pounder dry...Never touched them just fed and watered...
