Plants are getting heavier and now the diy hydroponic system kicks in with the weak points. My babies want to fall on one side and if it happens one side of the “pot” will turn upside and the plant with the pot will fall in the hydroponic system. Had to tie plants to stay straight. I can’t use the scrognet bc my diy hydroponic system doesn’t let me add new water or change it without raising the plant up with the lid.
