yes i know it has some bad purposes that some use it by, but im talking about the actual "plant growth stimulant" it's called by, has anyone used it in nutes of MJ?
I don't think mephedrone was ever used or intended to be used as a fertiliser, it was just sold as 'plant stimulant' for legal reasons i believe.
I dont see how any compound even related to those families could be anything but horrible to plant biology. These things tend to make most organic material go to shit.
