I love growing out monster cropped clones! I typically take my monster cropped clones once the plant shows sex, if growing out reg and not feminized seeds. The damage to the now flowering plant doesn’t mess them up too bad in the early stages of flowering. At least from what I’ve noticed, hasn’t caused me too big of an issue.
Once they root and hit my Hempy rez, they just flat out explode in growth. Sometimes crazy, insane, weird growth.
They do take a fair bit amount of time to root compared to regular clones, in my experience. Well worth the wait.
This is all things I’ve noticed with my setup and my minimal experience (I don’t grow trees, or many of them. Just supply myself utilizing 2-3 plants per run, at a max).
