if you want to pinch the top for doubling the main cola...i like doing it on the 3rd or 4th node early in seedling stage. this will give you 2 or more main stalks instead of one plus makes for easy training to grow along the ground surface. also search "FIM" at marihemp and overgrow...your uncle may have been talking about that practice. i've never tried FIM myself (on purpose) but supposedly it increases production by pruning lower branches in a special manner...all the info on it can be found with a search...

I was thinking though is that to late or not? However the way he told me to trim them is to do this.: Cutt the first to branches near the bottom off and then cutt the ones at the top short. :confused: but i have a filling that he dosent know what he is talking about, so that Rating: 5
