what is a F1 hybrid

Yeah some of the most vigorous plants I've ever seen are F1 hybrids.

"brainy female sexpot Cannabis Queen"? Oh my goodness!!! That's funny.

i have it in print if you guys are interested. it is in the book cannabis cultivation by mel thomas on page 118. says they grow 25% faster.

very good tip :thumbsup:

Yup, hybrid vigor is a proven thing. So I'd believe that claim about F1's.
