Sirius, I think you started this, but I know your actually trying to help, hehe. But youre correct and not, this stuff I am talking about DOES add weight, but its DESIGNED for curing plants.
Its NOT added after the weed is ready to smoke.
It IS added to the plant when it IS still growing (3 or 4 days before harvest).
It does something to help retain weight during the drying process. I dont know if its locking H2) molecules inside the plant or what.
But, its legal for sale in the US, claims to help retain weight during drying and curing process.
Not glue, or fibreglass, or heroin + dead kittens or anything like that.
