Here's what I found so far, some call it "
Girdling"
"I had the same strain without the nutrients injected and instead put in the soil. The injected had thicker trichomes with larger
heads. The injected strain turned darker colors and looked quite different when all was done. This strain was injected with nutrients into the stems. Never heard of it before, but the end result was phenomenal."
"Some of you may know of this method. Most of you probably have no clue what it is. It has been discussed before in the past,
and since there is no information I can find on it here, I will enlighten those whom do not know about the beneficial effects of
girdling your plants. Girdling is used in agriculture for many different types of plants. You ever see a 500 pound pumpkin or super large fruits? that may have been helped by a mixture of girdling and hormone treatment, and possibly other techniques. Girdling itself, has the
potential to increase not only your yield size, but also the individual size of each flowering cluster. It can also make your buds sweeter with a stronger aroma, and also speed maturity. Girdling is closely related to supercropping. Except supercropping changes the concentration gradient to allow for better passive transport within the plant. Girdling is essentially the opposite. Girdling can be risky if done excessively or improperly. It can kill any area that is above the girdle. You essentially want to restrict the flow alot or slightly by either cutting a complete 'ring' of the stems outer surface, or for an easier, safer method, tieing a strap around the main stem or
branch, tight enough to slightly restrict flow without breaking or completely crushing the stem. "
