I've heard of "Root pruning",but never read up on it.What is it????What does it due???? & will it kill my plants in done improperly???.At this point,i dont want to purposly do something for an increase & wind up killing them by accident(I would hate myself)I was told a long time ago that your root ball & fan/sugar leaves is the most important part of your plants,while they're growing & not to fuck w/them.I've already made the decision to manipulate my photo-period at peak resign production for a larger yeild(Got that idea from off of grow faq)they say 80% more light will increase a harvest @ 40% & only a few more days will be added to the flowering period.Is it worth a try????Has anyone tried this??? Please let me know Thanx.
