topping or super cropping autos?

Recomended? Does it work? Anyone try or know much about the auto way about doing it?

Yes. There are some auto strains that can be lollypopped and/or super cropped. There are some auto strains that have recommended instructions from the breeders that advise not topping and allowing one main shoot/cola. Imo any plant can be bonsai ed and/or supper cropped.
