I'm a new grower here and looking to experiment with the Kratky method with let us mix and mustard greens. I don't have much experience with liquid based nutrients, but I do have buffalo compost tea mix that the box says 1:1:1. If I use this tea for the nutrient solution, will this be good enough.

Also I do that have rock stones, can I just fill the net pots with regular potting mix and try the Kratky growing method in soil?
