Not sure about 90 percent.. but I trim very aggressively with a good deal of success. Basically everything below the canopy comes off for me.. When I prune/trim, I add a little B-52 to the mix, which helps with the stress. They don't even slow down..

The plant in the picture is a Critical+ in a #7 container. The trellis is 38" above the cart. Obviously I veg them for a while, but everything below the canopy is unproductive so I get rid of it. Believe me, the results are good!

Peace,

Farmer Rich
