The plants in my wick tote are doing great. The tote is a 10 gallon size, and the lid has 3 inch holes. The 20 oz wick cups fit in those holes, and the wicks hang down in the solution. The solution they had been in up to this point was 4-18-38 MasterBlend (2 g/gal), with Calcium Nitrate (2 g/gal) and Epsom Salt (1 g/gal). I changed out the solution with a fresh batch of Dyna-Gro 7-9-5.
This is the original wick cup video.
