Hempy bucket
In the next few chapters, we are going to build a passive hydroponics setup consisting of two Hempy buckets with an automatic weight-based irrigation system.
Overview
A Hempy bucket is a simple non-transparent bucket with a hole on its side, filled with coconut coir soil, perlite mix. It functions as a passive hydroponic setup by retaining water at the bottom 5 cm / 2 inch section containing pure perlite. We are essentially tricking our plant into thinking it found a natural water pocket at the bottom of the bucket.
