The Food Rising Mini-Farm Grow Box breakthrough

The Food Rising Mini-Farm Grow Box is a non-electric, open-source food production system that can be easily constructed using common tools and parts.

The system is:

  • 100% EMP-proof, using no circuit boards.
  • 100% non-electric. Requires no electricity whatsoever.
  • Key parts needed for the system can be easily scavenged almost anywhere (a paper clip, a pencil eraser, etc.)
  • Eliminates weeding.
  • Grows food in less than half the space of soil agriculture.
  • Grows food at waist height; eliminating bending over.
  • Uses about 1/20 the water of conventional soil agriculture.
  • Produces highly nutritious food with higher mineral density.
  • Can grow vegetables, fruits, herbs and even root vegetables (with an adaptation to be released later).

Credit for the teaching of "non-circulating hydroponics" belongs to Professor B. Kratky at the University of Hawaii, Hilo. His academic paper describing this technology is linked at the home page of

Health Ranger invents 3D printable components that make the system work

The key component of the system is the self-watering float valve, and to make this sytem easy to make yourself, I designed a 3D printable automatic water-leveling float valve designed around common parts that can be easily scavenged or acquired:
  • A pencil eraser
  • A paper clip
  • A garden hose washer
  • A common vitamin bottle

Using almost any 3D printer (and the correct filament, which is called "t-glase"), any person can print their own self-watering float valve and use it to grow their own food with very little effort and at very little cost.

In the following video, I unveil the Food Rising Mini-Farm Grow Box. More detailed videos are coming soon.
