    Capture moisture with the HH-2



This two minute fim was made for the Soil Association which shows how we can offer the same benefits to African Schools, villages and communities. Using our simple but very effective appropriate technology.

Good Gardeners are the originators of the No Dig farming and gardening sytem in the UK (1962) which teaches how to save water and carbon though No digging of the soil. This science increases the nutritional quality of the food produced (please see our web site: Sustainable Agriculture London.) Indeed the Director at the Haiti office of WFP, during the earthquake afterrmath said that the best world Food Programme is no World food programme but rather all peoples of the world grow their own food. Crop production is greatly increased with the Good Gardeners system and the effects of climate change can be alleviated with the tremenduous carbon saving and water holding capacity of our end product HH-4. (holds twenty times its own weight in water, ORFC., UK) We also teach seed saving which is important for future sustainability.

HH-2 technology first renders all forms of organic wastes including food processing wastes into an optimum fertiliser in 90 days, known as HH-4. This can be achieved and land based food production can be taught and effected where fish stocks are running out. Most sanitation systems are unproductive, a source of lethal pollution and are often very costly. Dry sanitation is effected with our HH-3 DRY toilet system which requires no water for flushing and no pumping out/disposal charges. This can be rolled out across Africa. Everything is collected in bio liners within the HH-3 DRY toilet and these are subsequently placed into the HH-2 Hot Boxes which are rat proof and fly proof. Everything is enclosed and is completely safe. The safety monitoring is effected with our supplied long stem thermmeter. Up to 24 toilet bags can be processed every week continuously with only one pair of HH-2 Hot Boxes. Thus this is a revolution in sustainable economics.The heat processing only takes 14 days, the automatic heat gradient is monitoed and recorded. Even younger students can learn this and record the information. At 14 days the material is removed  for maturation. At 30 days no pathogens have ever been at found at testing (over 20 years). At 90 days the material is bagged up for sale, as we do in the UK. We are selling for £1,000 per ton (pro-rata). Because our system is vermin proof we have developed the first Cholera proof sanitation system. This is very important and essential with the increase in incidence of Cholera around the world. The system could also be installed in designed refugee camps as a therapeutic activity and added source of safe sanitation and food security. (I.E., Haiti, 2010)

The resultant end product HH-4 will condition any soil type without the need for soil analysis. Marginal or so called unusable land can be brought into production with the HH-2 Horticultural System as we have demonstrated in many countries.

The long lasting HH-2 equipment (25 years) is the safest way to recycle all forms of organic and obnoxious wastes and make them into fertiliser in 90 days. This means that every farmer can replenish his land by employing other wise unused waste products. With the cleaning up of the towns and villages we will help prevent the spreading of flies, rats and mosquittoes. The quality of the soil is so improved with this No Dig system that much moisture is retained and crops can stand in the ground for much longer than normal. Thius it adds to the feature of food security and the origin of the term Farmacy. All your nutrition and well being can be obtained through properly grown food which does not have to be plied with chemicals for success.

We are reintroducing wheel hoes that originated about 100 years ago. We renovate them and export them with our equipment, which is also currently made in England.These create employment for adults and save thousands of man hours from hand hoeing. Machines and the need for oil become un-necessary with tthe HH-2 system and children can be taken off the fields and return to school.  The HH-2 Horticultural Sytem is income generating and facilitates the growing importance of utilizing human effluent as a fertiliser in Africa. The dilemma has always been 'how to do this safely' without the risk of the spread of pathogens. The science of Sir Albert Howard was conclusively proved when he took care of this 100 years ago. He was knighted for his work. Higgins has condensed this work into the HH-2 system today which features the enclosed HH-2 processing units that are fully monitored by temperature gradient monitoring. The system passes all the modern day Environmental Health regulatrions of the United Kingdom. Many many visitors have frequented our demo farm in South Hertfordshire including the Director of the Institute for Brain Chemistry, the holder of three medical awards. He summed up what we are doing in these words...

"what you are doing is revolutionary but at the same time traditional" professor Michael Crawford, 2016. Imperial College London. Prfoessor Crawford ran a hospital in Uganda for 30 years and is on the board of the Mother and Child Foundation, for Nutrition.

Professor Crawford invited Richard to attend one of his lectures at the Royal Society following his visit to The Good Gardeners Demo farm in Hertfordshire in 2016

"Thus the economic situation for all is improved. The relief from the stress of debt, good food security and improved nutrition is the prevention for many diseases including cancer. Cognitive development in children and subsequent mental health are also taken care of by improved nutrition and thus all can develop, flourish and prosper."   Richard Higgins, Chairman, Good Gardeners International. 

HH-4 was analysed by The Laverstoke Park Laboratory in the United Kingdom and it contains everything to activate a fully sustainable agricultural/horticultural food production system. John Innis Laboratory have commented that 'you have indeed manufactured fertile top soil. This is something  that takes Nature 500 to 1,000 years to complete. You have done it in 90 days.'

Good Gardeners train the trainers - anyone can learn how to preserve moisture, help feed the world, prevent disease and deal with waste all at the same time.

Good Gardeners ready for Africa

Date posted: 29 Sep 2017

How the Good Gardeners have moved on from Gloucestershire to Africa.... Good Gardeners International have undertaken surveys in Uganda gathering information for funding DRY sanitation facilities and their specialist food growing techniques for schools in Uganda that boost nutritional intake for the pupils. We surveyed Peters' School in Jinja in 2016 and the budget has been concluded. This money will pay for everything to train the staff and install the equipment; thus they will have a permanent DRY sanitation System. Our HH-2 equipment is easy to use and produces an optimum fertiliser/soil conditioner in one, using all the crop waste from their large gardens, waste from their kitchens and cooked food waste and all animal waste also. To see the details of the project go to our project link page This cleans up the entire school and grounds area and will eliminate the rubbish dump that is currently breeding rats and flies. with the unique end product HH-4, made from all these waste products,the staff will be able to gorw healthy crops of fruit and veg for the children without the use of any chemical fertilisers, pesticides or herbicides. They are currently not eating leafy green vegetables in their diet due to the cost of chemicals to keep off the pests that attack the leafy green vegetables. This results in malnutrition which is the cause of incomplete cognitive development of a child The HH-2 waste management system will enable the staff to manage thier new DRY sanitation system and save the most valuable commodity - water. Thus saving them lots of money on water wasted for flushing (we have a DRY flushing system) and costs and on sanitation disposal. All forms of sanitation waste are collected in bio liners and transfered into the HH-2 Hot Box system. The heat process purifies the waste of all pathogens. Thus a safe and effective fertiliser is made, which can be used on the school food growing gardens. This is known in Africa as 'productive sanitation'. This programme can be rolled out across Africa to save people not only from undernutrition but from malnutrition and starvation. Simply by collecting all these forms of wastes fertiliser can be made that is so effective it sidesteps the need for any form of chemical fertilisers or pesticides. The Good Garderns train the trainers to roll out this system of self help which enables any community to establish Food Security, improved nutrition and of course improved sanitation. The children can leave the school knowing the bascs for establishing Food Security learning how to grow food in abundance with the HH-2 Hortiicultural System. A teaching centre can be set up at the school for other schools to visit and learn the same techniques utilising our simple HH-2 equipment, which we propose to manufacture in Africa so that it will be affordable to many more schools and colleges and villages. Thus they will be able to supply all their kitchens with highly nutritios, fresh food, and have excess HH-4 fertiliser to sell to neighbouring growers and villagers etc., Thus they will have an income stream for their school based on their new horticultural experience of how to grow food in this perfectly organic way without having to dig the soil. This science is scheduled to be taught and funded in Mozambique with the charity NORGESVEL. in conjunction with Warwick University. Good Gardeners international have many years of experience behind them. We have a demo farm in south Hertfordshire UK where you are welcome to visit to see our HH-2 equipment in service, growing food for our local CSA members on discarded marginal land that has not been ploughed for 35 years. This solves our waste problem, improves our nutrition and prevents all kinds of ests and diseases ravaging our crops. The Director of Rothamsted research visited our farm and was amazed at the crop increases we have acheived with such simple technology. We hope you will be able to help expand our unique work and help improve the nutrition for the children of Africa. Please see our projects link page about Peters School "The HH-2 is long overdue in Africa. It will save lives, improve cognitive development and create Food Security" With Best Wishes, Richard Higgins DIrector, Good Gardeners International. … Read More»
