Looks like hydroponics..drain to waist..or flood and drain..the rez the plants are in will be filled with nutrient solution for 20-30 minutes at a time and then it drains back to the rez or else its drained too waste...those plants look toped and lollipoped aswell for a load of top heavy buds..hope this helps

Yes that does help. Thank you. Is "rez" that metal screen the plants are sitting on?


How do those processes differ from ebb and flow?

ebb and flow / drain to waste
or could be a NFT system i would think judging by the current moving around the cubes
the screen is probably there to give the roots a place to go when they out grow the rockwool

Drain to waste is not a system, merely denotes nutrients are not recycled, they hit roots once and trash.

The NFT or nutrient film means the tray always has a thin film running, thus its suited to DTW.

Flood n Drain fills tray much deeper periodically with dry spells between and uses more nutrients to do this, thus DTW would be too wasteful.
