Good explanation. I also thought roots started in water were hydroponic roots established for water growing. Only thing I may have missed is ...when you place in styrofoam cooler with jar of water what lighting method is used?
I have a cpl clones that I started a few days ago in soil only. They are doing good. Currently I'm using a LED full spectrum, low heat emissions, low energy use. 9 watts. 24 hour under light.
Any input would be helpful.
