Gravity is fucked, it is unhealthy, dude check out the sticky under Nutrients. It is not your friend.
I know how to get the yields you are talking about some people getting. It is all about strain, environment, optimizing nute ratios, environment, nutrient delivery technique, and environment.
You can get crazed yields once you start viewing every input to the plant from the perspective of optimizing the plant's health. If you can give it the best day of summer every day, it spends no time fighting anything to maintain homeostasis, it simply packs on weight all damn day. And it will be a happier, less stressed plant, so it will produce better sets of
terpenes, and it will be more medically effective.
Chase plant health, and it will treat you very well.
