An EC meter ent no use, i have the same thing as you just in a different plastic cover, and i've never used it, waste of good money. I also happen to grow hydro. Growing as difficult and technical as you wish it to be, i grow on the easy end of the scale, i get good harvests, as i'll show in 2 ticks, but i take very little care, i'm not sterile, i don't check it for weeks at a time, i abuse the shit out of them, i do just fine
other spend hundreds on additives and tools and look at it every 5 minutes, they grow good bud as well, cannabis is really very very easy to grow even if you fancy being lazy like I.
