   Hydroponics Ebb and Flow System
   Part 6: Reservoir Aeration

STOP! If you have just arrived at this website looking for hydroponics ebb and flow, you might want to go back to page one of this mini-farm plan.

NOW for the final touches!


14.
If you find that a small amount of water remains in the bottom of the tray (like 1/4”) after the drain cycle ends, you will need to raise the pots up off the bottom so they won't sit in the standing water (and rot). Place something about 1/2” thick underneath them to get them up just a little but not too high.


Whatever you use, it must be inert and not add chemicals to the nutrient solution (don't use bricks). Use something made out of plastic. We used some thin plastic slats left over from some old shutters.

15. Plug the water pump into the timer and set to fill 3 times a day, for only 15 minutes each fill cycle. (6am, noon and 6pm is good). Let the plants rest through the night; no feeding.

         TIP

Important: The air pump must be placed higher than the reservoir to prevent backflow of solution into the pump.




16.
The bubbler pump with airstone stays on 24/7. This oxygenates and aerates the nutrient solution, keeping it from becoming stagnant.

Earlier we listed the cheapest supplies we could find, to help keep the cost of this setup low.

However, you might want to go to a pet shop and buy an upgrade air pump for the stone. We bought this one for $20 and it is super quiet! Also look for a circular airstone.

This air pump has two outlet ports. If yours does too, then buy the “T” adapter and tie in both ports to one airstone. No use wasting half those precious bubbles!
