How to make a self-watering planter box
Rain water harvesting tanks (over 5000 Liters capacity in total) collect water from our house and shed roof into wheely bins and numerous 1kL caged tanks. From there a hose brings water to the garden where a vacuum cleaner pipe fitted with a watering can rose delivers water to garden beds. Saves a lot of walking with watering cans.

Hanging bucket as a worm farm as well as growing greens out of it is a great was to utilize fruit and vegi scraps from kitchen while picking greens out of it. It does not need to be watered as worm juice (brilliant fertilizer worms produce) is used/drinked by plants growing from the bucket.
