I'm very familiar with double-topping (one node apart) to produce a perfect square of 4 flowers. I have a rectangular indoor garden space and normally do 3 of 4 plants that way, side by side. The square (from above) shape is perfect for that.

When topping yet again (a third time), also on the node immediately after the last top, what shape (from above) does the plant take? I can imagine if a fourth top was possible, that would theoretically produce 16 flowers, and I think it would end up in a roughly 4x4 pattern. But when there's 8 tops, how do they arrange themselves? I'm asking because I'd like to know the overall shape of the resulting plant, for my tight garden space. Are they long and thin, perhaps roughly 2x4? Or do they form more of a circular plant? Or is it irregular, depending on growing conditions and genetics?

I've never tried it but I'm curious. You seem knowledgeable about triple top tech (on consecutive nodes) so I thought I'd ask what you've observed. :)
