Bean bag stuffing hydrophobia

I totally agree - it was more of a thought experiment.

What I have observed agrees with an earlier post  - that some soil mix will percolate through the base medium and form a  bridge to ground.

In a very large pot I grew OrienPet Lilies over a base layer of inverted 1 gallon plastic pots covered with landscape fabric ; with about 12 inches of planting mix on top.  The lily roots completely colonized the base layer with what looks like water roots - they adapted to the conditions and grew very well.

For capillary action to function the medium must be capable of being wetted. Foam repels
water and there would be no capillary action, so these small foam beads would not
provide better drainage.

I do this to make containers lighter for the inevitable moving around. And as for the
cycad seedlings - they didn't take P chem, and they are very definitely much less
rot-prone in deep containers with a layer of foam peanuts under then soil as opposed to
without the peanuts.
