- How to use ebb and flow flood and drain trays when bottom watering 1020 propagation and microgreen trays.
No matter if you use mesh bottom, trays with bottom holes, rock wool, soil, or other media.

SIMPLE. Which is how I like it. I have seen methods that use a single pipe. Once a day is less than I thought.
where can get I get the supplies for the supply and drain line? I cannot find this set up anywhere.
Pump and irrigation stores.
From What I read in "Hydroponic Food Production," by Howard M.Resh, the roots should not be exposed to air any longer than twenty minutes. This style of technique is supposed to create a healthier root system due to the plant needing to retain more nutrients within a limited time window. If the plants are not re-introduced to the nutrient water within the time window then the plant will die.
That is certainly the case in DWC or NFT, however the system you see here is primarily for microgreens and propagation in which if flooded 24/7 would lead to dampening off in microgreens or over saturation in newly sprouted seed starts.
In a system like this, is there an increased risk of spreading pathogens between the trays since the trays share the same water?
Regarding hydroponic recirculating water systems, one of the best practices for preventing contamination is to ensure proper maintenance and testing of nutrient solutions. It's also essential to use clean, quality-tested water sources and replace any components that may become contaminated. Additionally, grow systems should be regularly cleaned and disinfected and all equipment should be routinely checked for signs of wear or damage. We also know from previous experience that having proper cleaning solutions on hand ready to deploy at the first signs of trouble really helps. You don't want to detect an issue and have to wait for a solution to be shipped.
The only contamination problems I ever had with these systems is root mealybugs. They will spread very easily with this system. Other than that it's not really much to worry about.
I don't get how this works. If the drain is above the bottom of the tray then the tray will sit in water after the pump stops. If the drain is below the bottom of the tray then the water will never reach the tray.
