Note: After testing, we have found that this water recycling setup is NOT effective in removing orginc waste buildup. Therefore, not recommend to be used for growing microgreens.
Effort has been made to improve the DripGrow microgreens system created last time and
reported here. Watch the following video first:
One consideration is to recycle the water to be reused. Two Rona buckets were used to ensure the double filtration. First a hole was drilled on the side close to the bottom for each bucket so that a shutoff valve could be installed like this:

I made the following short video showing how everything works. If you are and DIY handy man, you know how to do it right away after watching this video:
I used a simple airlift pump made with a T-connector to feed water from the top of stacked grow trays, creating a water dripping flow. It is based on what is shown below with one exception: I added a one-way check valve at the water inlet so that it only allows water to come in and air cannot get out in an opposite direction.

I posted a video on YouTube, watch it now:

Before I came up with the version I call “DripGrow Tower”, I had tried several versions, some of which you can see in the video, including one made with a long bamboo pole. The time I spent the most was on various kinds of airlift pumps (some are shown below). Eventually I found that the simple airlift pump made with a T connector works the best.
