I am helping a friend out and she had the lights too high above the plants, so they started making long necks. I re potted them in red solo cups with their necks berried. Just wondering if the root mass will grow up above their previous dirt line or if they will only grow down from here on. They also had barely any root mass, not surprised since they had little light. I was told they are doing really good now, now that the lights are closer.
