Plant 1 is growing slower. I took the plant out of the cup and saw what looked like mould on the coco pellet also saw the root Turing brown so I too plant out of the pellet, rinsed the root and planted it directly into the clay pebbles in the cup. Also the roots haven’t shown the waters in the dwc yet. But plant 2 is loving life and is bigger that plant one also the roots look healthy and have reached the water.
