The HH-2 Horticultural System for Sale

HH-2 is the first update of the New Zealand composter in 100 years

HH-2 is NOT an ordinary composting system. Although the operation is simple, the training by HH-2 staff, and following the guidelines is essential to enable pest and disease free cultivation of flowers or food crops. The HH-2 equipment makes HH-4 The Plant Medicine with Nematodes which is a world class optimum fertiliser.

The HH-2 system produces and cultures specific fungi and bacteria that use thermophilic actions to make this potent fertiliser/soil “conditioner” from general waste inputs.


So potent is this fertiliser/soil conditioner that the need for yearly digging and ploughing ceases. The natural soil profile is restored, compaction is avoided, rainfall is captured and carbon is continually sequestered so that the full spectrum of living entities that make up a healthy living soil are facilitated and maintained.

This is all achieved through the use of the HH-2 “Hot Boxes” which can be filled with any type of waste of organic origin including:
• Farm waste, pet and animal waste
• Household Waste
• Market waste, food processing wastes
• Cooked and uncooked food waste

  • the system is rat proof and fly proof and is Cholera Proof too.
  • One pair of Hot Boxes can produce 12 tons of HH-4 annually
  •  The system can be used as a Human waste processor too, using the special HH-3 DRY Toilet system (optional extra).  Capacity one pair of Hot Boxes can digest the bioliners from 24 toilets per week.
  • The HH-2 is a localised alternative to Bio Digestors that cost millions and don’t produce such a fertiliser.

storing HH-4 for next years growing season


It takes just 90 days to produce the first batch of finished product HH-4. If operating at maximum capacity  every pair of HH-2 hot boxes can produce up to 1 ton per month or up to 12 tons per year (climate zone dependent), which will cover around 6,000 m² of growing area or raised beds etc., (.67 acres), of previously unproductive land. Once your land becomes “fertile” you will not need this application every year and it is much cheaper than buying nematodes in a box. You won’t have to keep replacing them. They will live in your fertile soil.

The HH-2 system is fully scaleable and multiple pairs of Hot Boxes can be installed at any one location. It is also possible to scale up for commercial output production.

All types of pests and disease are reduced to an absolute minimum and there are no slugs, snails or caterpillars in the growing site, nor rust in wheat, flea beetle in brassicas etc., black fly, green fly, white fly, carrot fly etc.,

The lead professor of Sustainable Systems at Rothamsted Research, Professor John Crawford, has visited the HH-2 farm and witnessed this and a 300% increase in crop production.

Cabbages of 3kg, beetroots of 3.4kgs and 19 inch parsnips were also produced.

You can now start to grow your own nutrient rich crops with your own fertiliser/soil conditioner and automatic pest controller.

all wastes reduced to 1/4 volume in one week
