Jack's 321 in hydroponics

If i have 5-8 gallon totes and let’s say each tote has 4 gallons a piece 20 gallons total and i was going to use the Jack’s would i put 20 gallons worth of nutrients or how would you do it

I mix in 4 gallon increments…easy to keep things simple and use a 5 gallon bucket…but yes you will need to either mix in a 20 gallon container or break it up into smaller increments…but either way you are still mixing per gallon


OK thanks man

I do 15 gallons at a time in my reservoir. No issues

like @Retiredoldguy said.
