I grow wheatgrass, broccoli and radish sprouts for juicing..I only use .5 ounce to a gallon ( they recommend 1 ounce) and I can't believe how fast and healthy looking these grow...I use 10 x 20 growing trays for the wheatgrass, and mason jars for the broccoli and radish, have not had one mold problem at all...I even experimented with the wheatgrass in a mason jar and it came out great...my wheatgrass is ready in five or six days, I don't use any coco coir, or soil, I just put the ocean magic water in the bottom watering tray and only add to it when dry...My broccoli and radish sprouts (I do them together and juice them together to get the highest amount of sulforaphane)are ready in 2 or three days...I only use this for them, but have no doubt this will work on anything thats grows...I'd take this myself in a minute if they made a human variety...highly, highly recommend this product for all your growing needs
