Thicker is probably better....but, not critical. If you grow them tall and lanky?...like I do... they want to fall over.
The colas make them top heavy. I have to tie them up or lean them against the wall...

It's said that a silica suppliment increases stem strenght. (silica blast)
Dutch Pimp Reviewed by Dutch Pimp on . How thick??? Just curious, how thick your main stalk is at the end of flowering? Really, This question should only be suited for indoor growers as it would only seem fair. Pictures would be great but, well will trust you... no really. And does the size of your stalk make a difference. :jointsmile: Rating: 5
