Kratky hydroponic radish grow with the Mars Hydro SP250. This is a quick grow test, using the Mars Hydro SP250. Since Mars Hydro sent me this light for review, they have upgraded the model to the SP3000. The radishes were started in an Aquaponics system, then later transplanted to the Kratky method. I show how to do all of this in the video, including mixing the Masterblend.
