What exactly does LST stand for and how does it work and what is supercroping?
Ok, I am not Zoo, but I can help. LST stands for Low Stress Training. The easiest method of LST is using some string or plant wire to tie branches of the plant off to the pot so they are bent over. Bending the plant tops downward does two things. Cannabis sends specific hormones to the top of the plant, and a certain amount to the branch tips, to keep growth coming from those sites. When you bend and tie down the main stem the hormone is no longer being sent there as it is no longer the highest point on the plant, instead the other branches and nodal points all strive to be the main stem. It also opens up the plant so sites lower down on the plant and sites that would normally be blocked from the light are opened up and exposed to more light. The end result is a plant that is rather short and bushy with many colas. With certain plants this will increase yields and ultimately take up less room. The only drawback here would be this technique can add a bit more time to the plants veg. cycle.
Supercropping is another training method meant to improve yields. The operation of supercropping is simply breaking the inner part of the plants stem without breaking the outer husk. By gently bending and/or rolling the stems of the plants the inner part of the stem breaks, but since the outer part has not broken it wants to repair itself rather than die. When the plant repairs the sites at which it was broken it scars, kind of like humans. There is additional plat matter built up at that site so it becomes stronger and thicker than it was before and the actual sites develop bulges that do kind of look like scars. With he increased plant material in any given point in needs more water, air, and nutrients, and subsequent portions of the plant also grow thicker and stronger. Again this can add to a plants veg cycle as it always needs 4 or 5 days to recover.
Both of these techniques are often employed by growers with limited space. They both can keep plant heights down but increase the amount of top budding sites. Both are very good, with LST being the easier of the two to utilize.
