These HST methods are much more useful for large outdoor gardens than LST methods, and they generally require less time and materials. Although HST should primarily be done in the vegetative state, “super cropping” can be done early on in flowering, but stressing your plants during flowering is not recommended.
Topping is a simple HST method and requires no tools besides your fingernails. The goal is to remove the top of the plant, which will result in the top buds turning into two new branches. Additionally, it sends a shock to the rest of the plant that promotes growth in the lower branches.
This process can easily be repeated multiple times as the plant grows in its vegetative state. It will produce a well-rounded, healthy plant with numerous colas.
FIM (“Fuck I Missed”)
A more complicated version topping, FIM involves removing a very specific amount of the top portion of the plant. By scoping out only the topmost region of the new growth, the goal is to produce four off-shooting branches instead of two. Because of the complexity, this method takes significantly more time. It also puts your plant at greater risk of infection because you’re no longer making a clean cut on the stalk of the plant.
