Hey, maybe i can help clear this up.

Those are 2 seperate methods for creating a drainage layer. Eggcrate and Hydroton
The substrate barrier should be weedblocker netting. It keeps the soil from falling down into the drainage layer.

Eggcrate Method- Bottom of tank to top
1. 2-3inches off bottom an eggcrate barrier.
2. Cover the eggcrate with weedblocker (its a mesh material). This keeps the soil from falling down into the 2-3inches of drainage room.
3. Substrate
4. Plants

Hydroton method - Bottom to top of tank
1. 2-3inches of hydroton balls
2. Weedblocker netting
3. Substrate
4. Plants

You see, the hydroton is just acting as a resevoir for the extra water. But when you are using the eggcrate method there would be no sense in using hydroton as well because it would just take up more viable space for the resevoir.

I hope thats clear. I am having trouble explaining today. Sorry
