how do we put the plants in it?

[Lathrop]

We built your 11 plant hydroponic garden, but how do we put the plants in it? We saw the picture with a plastic cup in the bottle, but how does that work? Lathrop Adv. Tech. Class

About the little cups again: So plants go in the little cups and cups go in the 2-liter? And the roots are in the cup, or do they extend out? How big should the holes be? Thanks!
