I will try to make this understandable .....
I do not strip or remove lower branches. They are the quickest way of getting energy to the roots and will provide the largest solar panels.
Because I was attempting to grow a monster, I topped the main stalk at the fifth or sixth node.
All lower branches remained on the plant and were topped at the third, after showing four nodes.
The two new "tops" on the main were topped at two, after showing four.
All secondaries between the main stalk and the topped locations were topped at three.
The access beneath the plant was accomplished by growing in a 16 1/2" raised bed with about nine cubic feet of soil. By the time it was impossible to circumnavigate the plant there was at least two feet of space between the ground and the branches (the branching was growing in an arc which increased the amount of available space below the plant as they grew). That was thirty years ago and I was quite a bit more nimble so crawling around wasn't too bad.
Depending on the height of your tent, you can raise the grow medium to provide as much space as you need.
Remember, with this method your radius will be about the same as your height, more or less (i.e. a five foot diameter will equal a three foot tall plant, more or less).
Here's a photo of my current grow a week
into flower, sorry Emilya, after flip. This one is 16" tall, before this mornings training session.
