I really did call the company and spoke with people to get that ppm or whatever it is down from the 500, and used the drinking excuse to insinuate exactness or close as possible per drs orders. They were very helpful. lol. I am gonna try it on a plant next round or two, got my nerve up. I know Im glad I got a bunch of Heisen's gear on the cheap first go around, and right up my budget alley, got some Usefuls gear, killed my last cv gear, rip, and bout got my regs give away. I keep seeing those clone stories at the other place and gettin offers. Kinda hard not to try it at least once or price. I know some of the cloners I talk to, one is cheap on the shipping and does it right, others are cheap on the clones, expensive on the shipping. But if legit cuts. man, takes half the battle out of the reg bean deal, unless looking for males I guess or special pheno to then make cuts and share or sell.
