Due to many misconceptions here in Cdot about hydro systems and what they are called...I thought I would start a description thread for the Newbs.

1st you have a Bubbler,=deep water culture, roots suspended into nutrient solution with an airstone supplying the oxygen

2nd Drip,=recirculating drip or, drip to waste.
Pump is placed in rez and plumbed to driplines that provide nutrients from through top of plant ~via~ netpot

3rd Aeroponics,=you have an aero system=sprinklers of any sort...plumbed to a pump, the sprinklers provide nutrients from under the top, and the open tub or channel provide oxygen.

4th NFT,=nutrient film technique=running a consistent film on the bottom of a tray sloped down 1' in 40' run.

5th Ebb & Flow,=pumping solution to tray for chosen periods of time and then draining to allow oxygen to the root system. usually periods extend until medium is almost dry, then timer turns pump on again.

"Hybrids are combining DWC and drip, generally, which would be recirculating DWC ~via~ driplines.
or, if you have sprinkler inside tub...What for???"

Although all these hybrids are cool, and work. Keep in mind that "ALL" methods work extremely well, all by themselves. In commercial; applications; NFT and DWC are generally used for lettuce and other veggie crops, drip for almost everything else,and aeroponics and ebb and flow are used for rooting...primarily.

Just prescribe to the KISS strategy
Hope this helps. Peace
