Where I live there is a legal limit to how many plants we can grow. So, I had an idea.

If one were to root 2 or 3 clones together (say in one rockwool cube) one would probably wind up with 2 or 3 fat main stalks all originating from the same root mass - they may even graft together.

If you then transplanted that into your setup I fail how to see how it could be counted as more than a multi branched single plant.

So in the end you would have 3X the nodes, 3X the branches and 3X more product in general while still counting it as 1 plant.

Any reason this wouldn't work?
