What's the science behind cracking open a plant's trunk? Seems to me the inside would callous over thereby reducing the amount of cell tissue conducting fluids/solids/salts.
Not as common as flushing and defoliating, but it's an oldie that just won't die. While there are quite a few who do it, even in the smaller dutch forums they usually get ridiculed for doing it.
Those who do it claim that the science behind it is that restricting nutrient and water uptake ==> stress ==> more THC.
Usually done around the same time the same folks start flushing or stop feeding (same thing for many), so 2 weeks or so before harvest... it's like giving a PK booster around the same time the buds normally swell up too, or removing leaves and 'see' more bud.
It's supposedly a technique from south east asia, I haven't found any dutch reliable agriculture resources that mention it and seems to be an advanced mj growing technique only if you know what I mean.
The outdoor scenario to which the myth is typically contributed is too largely perception. For many (forum and bro-science) growers in NL a yellow cannabis plant is a ripe cannabis plant, yellow/brown/dying = ripe, so causing premature yellowing is perceived as premature maturing/riping. Hence the voodoo doll, it's voodoo, not science.
This is an old school pic of my 36 site sog table buds. Come to think about it, I did quite a bit of defoliating with the amount of plants in the 3.5x3.5 tables to get these buds to fit properly and fill out. This is a defoliated bud I pulled up from the deep down hard drive of the long long ago... Before I realized I was defoliating.. Kush...Buds were dried to the size of my arm.
