i just got my fox farm grow big in. The instructions say to add 3 teaspoons per gallon.. Ok well thats a no brainer, with the aero garden we are only working with a 1 gallon res.

I assume that i want to do a complete flush ( taking out all the old water and put fresh water in) since i have old nuets in there from the tablets the system origionally came with. Is this correct?

Also how often do i add the 3 teaspoons into the res.?

thanks all!
