Those are neat little ones. I have had the pleasure of 2 so far in my tenure, growing. The 1st was a blue cheese and the 3rd leaf became absorbed as it reassimilated to a regular 2 leaf node. But the plant had a floral taste once cured. This last one i got was a mango. It as well assimilated itself back to a 2 leaf node plant.
I would like to see pictures of the technique you speak of where the tops multiply. Maybe more the result of the technique. Good luck!!!
