The cap fits inside the top of a 4" PVC S&D pipe. Water is fed into the side of the cap with 1/4" tubing. There are many holes in the bottom of the cap around the outside edge. Water falls through those holes and into the inside of the pipe. The sprinkler head arrangement described in other items on this website are not required with the caps.

The base fits on the outside of the 4" PVC S&D pipe at the bottom. Water falls out of it and into the reservoir or drain pipe below the 2" hole at the bottom of the base.

Aquaponics and Organic Systems

This irrigation system is specifically designed for organic nutrient production where micro-organisms supply the nutrients for the plants rather than hydroponic salts. Organic micro-organism based systems require a lot of surface area for dense aerobic community habitat. Organic systems such as aquaponics also typically involve more solids and require larger passageways for the free movement of micro organisms. The Nutrient Irrigation Cap provides abundant habitat with its sand and biochar media as well as natural filtration and break down of larger suspended solids and supplements.


Hydroponic nutrient based system do not require the filtration and micro-organism habitat and so are used by excluding the media component in the cap. 

Optional Cap Media

  • Using BioChar and coarse sand in the cap provides as much surface area for micro-organism as gravel beds
  • Helps filter suspended solids
  • Micro-organism break down solids faster in the aerobic cap than in water
  • Provides a convenient place to add minerals or other suppliments such as kelp and worm castings
