By the way, FIM stands for Fuck I Missed. The technique was discovered by accident when a guy was trying to top his plant and multiple stems grew from the cut area.
I wish I was blazed lol. I don't have to much sideways space, I have way more height space. Is there any method kinda of like F.I.M, that would make a plant grow tall instead of short and bushy. I just want the biggiest yeild possible. I would have used the F.I.M method but I dont have enough sideways space.
do NOT raise the light, you will cause the plant to stretch.
trim the plant.. but below the nodes as if you were cloning... take off excess leaves. stand above the plant and look down, if you cant see the soil (or whatever medium you;re using) neither can the light... Give it a HEAVY haircut, dont worry if it looks bare, give it few days and it will start to get bushy. u can do this quite frequently in veg. DO NOT do this in the flowering stage.
