You can actually cut plants all the way in half on most of my current offerings as long as you haven’t cleaned up the lower growths yet. I actually recommend it. It seems counterproductive only on paper. In reality you vastly supercharge the growth by doing the toppings as low as possible. The reason for this is you create a situation where the roots are more established than the plant itself. Suddenly the flow of hormones pushes hard into the already established branches and the plant absolutely skyrockets in growth.
Certain genetics don’t like this strategy, but almost all my current genetic offerings will respond extremely well to it, I tend to breed with topping traits in mind.
So basically find a part of the plant midway on the plant that has good branching already, cut right above the last good looking branch(one with multiple nodes already). Then clean up the plant so it has 4-6 main branches. You will achieve a stronger anchored base by doing this as well, which will better support heavy flower weights later on.
The strategy can also be applied to each new top at a later point as well. If you want amazing yields this is a nice way to accomplish that goal. Topping near the top creates a little bit of lag by comparison and doesn’t anchor the plant as well.
Typically speaking I let my plants grow 12-18” and then cut them in half to make them into bushes rather than Christmas trees
