As microgreens are easy to grow and suitable for the winter season, I worked on this for two weeks and came up with a way to automatically pump water to feed my microgreens using airlift pumps. Better still, I built two bucket filters in order to reuse the water. Here is the YouTube reporting this:



I used two Rona buckets and drilled a hole on the side close to the bottom for each bucket so that a shutoff valve could be installed like this:



Then I added enough water to each bucket to make sure there was no leakage whatsoever:



Then each bucket was filled with these things in this sequence: pebble stones/gravels, perlite, crushed coral, and sand.



Another consideration is feeding water from the bottom of the tray containing seeds already sprouted and having leaves - trays on other levels contain seeds that do not have leaves yet:



Here is a closer look at the top tray:



Note that the tiny whitish things around the roots are root hairs, not mold. Root hairs are useful in helping microgreens to absorb moisture even in the air.

Strange, these is no section called "Microgreens" and I do not see many posts on microgreens - why?
 
Hey, sticks and stones baby. And maybe a wee mention of my stuff:
