The HH-2 Horticultural System (HH-2) is slowly gaining recognition as the most highly effective solution to many modern day agricultural and waste problems. There is an urgency to address worldwide food shortages and waste issues. HH-2 has the potential to be a “game changing” technology – but financial resources are required to bring this methodology into widespread use.
Current systems of agriculture and horticulture plough or dig over the soil, thereby losing valuable moisture and carbon, which is consequently depleting the soil at an alarming rate (Soil erosion). The world is losing 24 billion tons of topsoil every year because this action disconnects the soil form its natural formation of layers and so much subsequent tilling is required to reconnect the soil so the seed planted will grow. Ploughing causes depletion of the organic life in the soil which in turn increases the requirement for ever more chemical fertilisers and pesticides to make it possible to grow a crop and keep off the pests and diseases which attack because the soil is unhealthy. The soil becomes more like concrete with chemicals added.
In Africa and India the loss of topsoil is blown away in the wind by this overworking of. Also valuable moisture is released and thus the demand for irrigation is increased. This is depleting the subterranean water aquifers from where drinking water is acquired.
Africa and other developing regions dump human waste and other garbage into the ground in such a way that causes pollution by the contamination of water courses, the breeding of rats and flies etc., together these cause the largest loss of life in the world (WHO).
One Solution to Two Problems
With over 20 years of research The Good Gardeners International have perfected their HH-2 Horticultural System as a localised solution of source separating garbage in schools, hospitals, towns, villages and refugee camps etc., and processing the organic fraction (often 70%) into a unique soil conditioner/fertiliser in only 90 days. This low cost technology is easily operated by the people themselves after they have been trained by the Good Gardeners staff. The end product is known as HH-4 and is an optimum food growing media and soil conditioner in one. From these waste streams income is generated and is one of the surest ways to bring any community out of poverty.
The HH-2 Horticultural system will:
- Eliminate water pollution, rats and flies and rubbish piles
- Produce an optimum fertiliser to grow pest and disease free crops
- Dramatically improve the nutritional content of food produced
- Help educate users in simple ecological waste management and good practice agriculture
- Create micro businesses with income generating activities
- Help reduce malnutrition
- Turn human and other sanitation wastes into a valuable soil preserver and rejuvenator – within 90 days
How HH-2 works
The “secret” of the HH-2 system lies in the culture of the initial specific fungi and the subsequent bacteria that by thermophilic reaction make a potent fertiliser/soil “conditioner” from the measured inputs of waste products.
With the balanced inputs the insulated HH-2 units maintain the correct moisture balance that ensures an optimum heat curve in the first 14 days of the process. The right fungi and bacteria grow and develop and thus all pathogens are destroyed within the system. The operation of these units can be easily learnt by the staff and inhabitants.
This is all achieved with the use of the HH-2 “Hot Boxes” which can be filled to four feet deep with all manner of organic wastes including:
- Farm waste, crop waste, biomass
- Household waste
- Cooked and uncooked food waste
- Food processing waste
- Animal waste, cow dung etc.,
- All types of sanitation waste from the HH-3 toilet system
Additional locally sourced “essential ingredients” are then added to the mix to start the unique cultures growing. This results in HH-4, the most micro-organically active substance on Earth, with supremely effective moisture and carbon sequestration properties
No harmful pathogens have ever been found in HH-4
These specially insulated Hot Boxes are designed with aeration vents, no moving parts or electrical hook up and can be operated by selected local staff after training. The remarkable end product, HH-4, is produced in only 90 days. On extensive analysis no harmful pathogens have ever been found. This product is of high value and sells in the UK for £1,000 per ton.
The Complete HH- 2 System includes HH-3
Richard, who is co chair of working group 3 with SuSanA (Sanitation to Agriculture) has designed and developed the HH-3 DRY Toilet that requires no water for flushing and works in conjunction with HH-2.
The HH-3 DRY Toilet collects fecal matter through an ordinary looking toilet. Two options are available for using this toilet system:
- For large communal applications the toilets are fitted in safe and secure cubicles on a raised toilet enclosure. The waste passes directly into the HH-2 Hot Boxes.
- Alternatively biodegradable liners are fitted inside the toilet units which very cleverly filter excess liquid into a collection system for recycling back into the HH-2 units. A weekly collection is organised on a localised basis with replacement bioliners installed ready for use in the new receptacles.
- There is no need to flush the HH-3 DRY Toilet with water. There is no smell or unsightliness at any stage of the operation. Thus maximum amounts of water are saved. It is mostly drinking quality water that is flushed down toilets the world over.
- The HH-2 and HH-3 will replace the need for the digging of unproductive pit latrines and the inner working of UDDT toilets can be converted to suit HH-3 super productive system. Contamination of ground-water from badly managed sewage systems is thus avoided and a productive sanitation system is thus established.
When HH-3 DRY Toilets are fitted into individual homes, one pair of HH-2 hot boxes, strategically placed, will have the capacity to continually handle and sanitise the waste from 24 houses. Ther operation of this system is income generating and self-sustaining. Thus the ancient methods of reclaiming the full range of nutrients from all kinds of waste is re-introduced with the HH-2 Horticultural System
The Unique Properties of HH-4
In a time frame of 90 days the HH-2 System produces a material, HH-4, which when applied correctly to the soil rapidly reproduces all the necessary organisms that make up a healthy soil structure. The larger of these organisms is worms and without them any agricultural situation is compromised. Healthy soil automatically reduces the incidence of pests and diseases in all crop types.
This HH-4 material facilitates the macro element, namely earthworms. These lowly creatures are ignored in modern day agricultural and horticultural systems and this is unfortunate as they produce 5x more Nitrogen, 7x more Phosphorus and 11x more Potassium in their castings than is found in surrounding soil (Balfour).
This system is more reliable and sidesteps the need for vermicomposting as it produces millions of worms in your soil which is where they naturally live and generate themselves in vast quantities. Fertile land will hold up to 16 million earthworms per acre (Howard, Darwin).
So potent is this HH-4 “fertiliser/soil conditioner” that the need for yearly ploughing ceases. The natural soil profile is restored, compaction is avoided, rainfall is captured and absorbed, carbon is continually sequestered. This together with revised surface water management, also taught by the staff of Good Gardeners, will reverse and greatly help in the adjustment to climate change. (more carbon is lost to the atmosphere by ploughing the world over than through any other source, BBC world-service)
Any school or community can grow abundant fruits and vegetables and will thus increase their potential for a more Vegan lifestyle which reduces the stress on land resources. With a much increased standard of nutrition than conventionally grown food whole communities will be able to improve their cognitive development which will in turn reduce the incidence of mental and physical health problems.
This all starts with the cessation of ploughing or digging the soil and by improving the microbial fauna and flora in the soil. The health of plants grown in this improved soil will dramatically affects both the health of animals and man that consume the crops grown on it. The children and staff in each of our school where we can install this project will have increased health benefits. The Nutritional quality of their diet will change and the children’s full capacity for development will be realised. Plus they will be learning the most important skill of how to produce their own healthy food and prevent their sanitation from polluting their drinking water.
Each project set up by the Good Gardeners will be a potential teaching centre for other neighbouring communities and villages etc.
