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.
