I have a Berkey system that gives great tasting filtered water. Is it ok to use the water for my grobo grow?

Check the ph and ec.

Do you mean ec .1-.2 or actually 1.0-2.0?
I’m hoping you mean ec .1
You will need to buffer it with calmag for ph

If I wanted to CalMag my water prior to filling Grobo (using Grobo bottle 5) any idea how much per gallon I would use?
My grobo fills with CalMag before dosing the other nutes. Any particular reason why you wanna try adding it manually? Does your Grobo dose it first as well?
I’m running Mammoth P and I’m trying to figure out the best way to utilize it in the Grobo. I think what I’m going to do going forward is administer Mammoth P directly into the reservoir after the Grobo has dosed pH, nutes, and calmag based on amount of water taken in during fill. This seems to be the only way to properly administer the it as it is supposed to be mixed in after everything including pH. @chris_barfield do you see anything wrong with this plan that could end up harming my plant?

Shouldn’t be an issue … but again you only learn by Messing up
