After the third set of leaves have developed, slice the growing shoot off. This causes the branches surrounding the main branch to grow more. The plant starts to grow into a bushier shape, developing a wider canopy. After the first topping, you can top again once the plant grows another set of three leaves. Topping can be done 3 or 4 times during vegetative growth. The more you do it, the wider a canopy you will get. A wide canopy will have more tops, producing lots of quality buds.
To lollipop your plants cut the lower branches off during the vegetative growth phase.
Even though branches are removed, Lollipopping can actually improve yield because the plants growth energy is redirected to the top half (not wasted on bottom half).
Removed branches can be used for clones.
The idea with bending and crimping is to damage the stem to force the plant to rebuild itself stronger. To do it, hold the stem with one hand and with the other hand gently twist the stem back and forth until you hear it breaking. You have to be careful, obviously, not to snap the stem right off. Smaller branches can be crimped simply by pinching them.
Trellising techniques allow more light to reach more parts of the plant. You can position the branches so that they get the most amount of light and don’t block other branches. You can use wooden stakes, tomato rings, or netting to create structures in your garden that you bind the branches to. Twist ties, gardeners tape or string are used to bind the branches to the structures.
During flowering, bend the top cola sideways and tie it down so that it is lower than the side buds. This will cause the side buds to grow more vigorously. Once the side buds have advanced their growth to your liking, the top cola can be unbound. This technique results in multiple larger buds at the top rather than just one primary top cola.
