Question on Roots and Transplanting

[lumbo]

I’ll have to try that on a few and see how it works in my case. Kinda reminds me of what you can do with tomatoes to stimulate fruit growth–cut in a circle around the plant to restrict the root growth and force the plant to focus on producing fruit instead of more veg. Different in this case, I guess, but same general approach. Looks like you use milk cartons, too, for the intermediate stage. Is that right? I prefer square containers once the plants get bigger. Easier to fit them all in my grow space.
