Thanks much friend! I normally use Pro-Mix HP soilless medium with Advanced Nutrients product line. The medium is pretty much sphagnum moss with perlite added, and I moisten the medium with a very light dose of nutes in pH adjusted water. This gives the seedlings a balanced diet, then I increase the nutes as the cannabis seedlings grow. I mention this to you since I plan to do something similar with the wheatgrass unless you see a flaw in this plan.
I’ll look at the video you linked and they may address this very question. I’ll need a tray with drain holes that will fit in my tent, plus some wheat berries to begin. I bought a masticating juicer after frustrating years with centrifugal juicers, so I’m ready to juice green leafy products the other juicer simply would not handle with efficiency.
I need to find a source to buy a tray and wheat berries, and if you have suggestions, I’ll be most appreciative! Thanks!!
