I decided to buy the starter kit... im a grower not an electrician...
It seems to be working... my plants look happy and growing strong. Super easy to set up and didn't have to worry about zappin myself. I asked them about the claims they are making about THC and CBD on grasscity and they sent me this as a reply... a testimonial from one of their "customers":
"My first experiment, I Tested 3 strains without
using Earth & Grow. Then I tested the 3 strains
again the following Grow Cycle while using Earth
& Grow. During the experiment I maintained the
same feeding schedule, harvest time and growing
conditions. The three strains I am running experiments with are
NYC Diesel and OG Kush. These are the first results without using
Earth & Grow
NYC Diesel and
OG Kush. These are the results after using Earth & Grow for 8.5 weeks in flower
NYC Diesel and
OG Kush."
Seems legit, but you never know... i did some quick googlin and found this... an article about researchers at the university of arizona using electricity to increase chemical levels in plants...

Pretty cool if you ask me. Makes sense that the Earth's electrical charge would enhance plant health... this company does the same thing with humans
