I just realized it's quite possible i've been combining DWC and Ebb & Flow..

In Ebb and flow is it possible to have roots suspended in just air?? This is how Ive been planning it...

If I am doing ebb and flow, does that mean that all my roots need to be contained in a growing medium?

The way Ive planned is to have only the net pots filled with clay pebbles... they will then grow down into the buckets- but this is not DWC so the bottom part of the buckets will not always have water in it...

Will the roots dry out if I don't fill the entire buckets with hydroton?

any help is super appreciated!
