A few months ago, I harvested a Blue Mystic autoflower. Instead of just cutting the trunk, I clipped off the branches, and left the pot with stump in my shed. My wife saw it a week later, put it outside. A few weeks later, I went to empty thepot, and found the plant growing branches! Here it is, with a bunch of frosty buds that are almost ready to harvest again! I'm going to see if it will cycle again. I have harvested 2 Auroras the same way, and they have some shoots showing!
This is the second harvest!. Might be 12-14g when dried. I put the stump back outside to see if it will cycle again. Not as productive as cloning, but a lot quicker.
