I am not advanced enough to get devices that measures PPM. The only thing I measure is nutrients, flowering "roids" and PH. Lately I've been measuring how much I water and writing down the date and what u performed. I need to step up my growing "professionalism" if I want to yield at least every other months which is posible. I got slightly over 8oz on first harvest of 4 plants. This time I have the legal amount or maybe 1/2 dozen or more...I am not good at math lol.
Scrog tent looks fucking marvelous. Tent is 2.5'x1.5'x3'. 3 flowering (week 2) plants growing in a 18 gallon storage container and with the SCROG Net.
