Nice, I didn’t realize there was a topic regarding this already. This turned out to be a good test of the GML method. I have stripped leaves previously at week 3 and only leaves I thought blocked a lot of light. The main difference I see is the bud size on the bottoms is much larger when the leaves are stripped, I saw no slow down in growth and the additional stress everyone talks about was not seen on these plants.
I will run a test soon. I will run 2 clones of the same strain and fully strip one, and only the main light blockers on the other, this will give us a good comparison. I will post the test in the GML Leaf Stripping topic.
Different strains will react differently, but so far I have had no adverse effects from doing it, other than bigger buds on my lower branches.
