Second Topping after 6th node (7th actually) of new growth. I then cut down to the third node leaving it and the first node, but I removed the second node/leaves. I used HST and positioned the limbs. This is the 'manifold' set. Basically 4 colas and 4 branches rather than 8 whole colas as with using the mainline approach. Cant say Im a fan of this method; it has fewer cuts than mainline, but it places the limbs at 2 different distances to the roots. We will see what we get in this kind of set.
