Well I'm starting an indoor reversal run, gonna try reversing two auto's & two photo's. This is not my first attempt but hopfully will be my first successful run!!! My first question is what is the best delivery system for the c.s. to penetrate the plants cell walls? Also I've made my c.S. before using a home made c.s. generator with a shitty ppm meter mind you, is it possible to use Trace minerals research C.S. and mix the right ppm I'll have a photo of the c.s. also since I am buying the solution should the ppm be higher then home made solution. Also how do you know when the solution is working once you do start using it!!!! Sorry if this is a thread that's been done but I enjoy the interactive part of this site also!!! Thank you in advance!!!!
