Looking great, trying to find out how it works 
, excuse my ignorance, when I saw dequilo’s hempy pots I made a search to see how they worked:
still have two questions regarding yours: the tubes are draining tubes? You water from the top and the remnant water just goes to a deposit in the bottom? Also I wonder if putting the hole higher would mean more water remaining and more time between watering, thanks for sharing, will keep an eye on this …
