You don’t need AI to stop weeds or measure for chemical fertilisers with HH-2

California was featured on the BBC World Service as having a great solution for Vegetable production by employing AI technology to identify which are plants and which are weeds to be able to either supply the required chemical fertiliser or weed killer.

If there is a power cut, as is often the case in the USA with excessive demands on the electrical grid with hot summers for air conditioning or from cold weather heating requirements there will be none of the above…to grow the crops.

If we rely on AI for anything it only depends on the electrical supply.

Growing food without dependence on electricity is a much better approach for sustainability. Of course that includes all heavy machinery that is is also dependant of oil (fossil fuel)

We have a programme that can grow food completely sustainably which depends on neither of the above. This is an important technology that has to be preserved and expounded across the world for human posterity.

WHAT IS THE HH-2 SYSTEM

The technology operates on two levels.

1. The HH-2 containerised system that can fertilise  previously unproductive land acre by acre into pest and disease free cropping with high productivity in the same season that doesn’t rely on Entomology.
2.  The HH-1 windrow system that can fertilise previously unproductive land hectare by hectare in a similar way. Of course this system is mechanised and is subject to the supply of electricity and the supply of oil (fossil fuels)

Both systems however only use organic wastes to fertilise the land. There are no chemical fertilisers used or chemical weed killers etc.,  They are completely organic systems and neither rely on Entomology.

When we asked AI this question here were the results.

Question as of 16.2.26

does anyone in the world have a system of food growing that uses no chemical fertilisers or pesticides to grow nutrient rich food on marginal land in the same season without having to plant trees or rely on Entomology or do any weeding? (weedless farming)

Answer as of 16.2.26

Here’s a clear, realistic answer to your question:

👉 There is no known globally-adopted farming system today that simultaneously meets ALL of the following:

• grows nutrient-rich food 
• on marginal land 
• in a single season 
• with no chemical fertilizers 
• with no pesticides 
• with no tillage 
• with no trees or agroforestry 
• with no reliance on insects, beneficial organisms, or manual weeding
  in a fully weed-free way 

In other words: no one has created a 100 % truly weed-less, chemical-free, no-care, seasonal food production system that works on marginal land without relying on ecological processes or interventions.

THEN WHEN I ASKED AI  WHAT ABOUT THE HH-2 HORTICULTURAL SYSTEM….

Here’s a clear, factual overview of that system and how it actually works based on the organisation’s own descriptions:

🌱 What the HH-2 System Is

• The HH-2 system is a purpose-built composting/horticultural system that turns organic waste into a specialised fertiliser/soil conditioner called HH-4 in about 90 days. 
• Members of the charity and users report applying this fertiliser directly to soil without tilling, forming fertile soil surfaces. 
• The HH-4 output is described as containing the “correct fungi and bacteria” and having macro- and micro-nutrients suitable for plant growth, which in their view eliminates the need for synthetic fertilisers or chemical pesticides/herbicides. 

🍅 What Supporters Claim It Achieves

According to the organisation and some anecdotal reports:
✅ Soil fertility can be significantly increased in a short period, even on depleted or marginal land, by using HH-4.
✅ Pest and disease incidence (e.g., slugs, snails, caterpillars) is reportedly greatly reduced in plots grown using this approach, without chemical controls.
✅ Crops produced with this system are claimed to be nutrient-rich and have good storage and health characteristics.

Supporters cite hands-on examples such as very large vegetables and productive community gardens as evidence, and some projects (including in Africa) are using the HH-2 system to produce food on poor soils without synthetic inputs.

⚠️ What to Understand About These Claims

While proponents position HH-2 as a fully chemical-free, low-labour, high-yield approach, it’s important to clarify:

🌾 Independent scientific documentation or peer-reviewed trials are scarce:
The main information about HH-2 comes from the charity’s own publications and user reports. There isn’t widely available independent research in agricultural science journals (e.g., by universities or government bodies) evaluating HH-2 on the full range of soils, climates, and crops.

👨‍🌾 Weeding and management aren’t guaranteed to disappear:
Even with fertile soil and healthy plants, weeds still grow, and successful cropping usually requires some form of weed management — whether through mulching, cover cropping, spacing, or observation. No system established in mainstream soil science has been proven to consistently require zero weeding under all conditions.

🧪 Claims about built-in pest control should be approached with caution:
Descriptions of HH-4 acting as an automatic pesticide or disease control are promotional. In mainstream agronomy, pest pressure is complex and influenced by ecology, plant health, weather, and many variables; single products rarely deliver universal pest control without active integrated management.

🌍 How HH-2 Compares With Other Organic/Regenerative Systems

The HH-2 approach is similar in spirit to no-dig, on-farm composting, and regenerative agriculture methods that build soil life and reduce synthetic inputs — practices that do exist around the world (e.g., permaculture, Korean natural farming, biodynamic methods). The difference is that HH-2 packages this into a specific equipment-based composting system designed to deliver a consistent fertiliser product.

📌 Summary

Yes, the HH-2 Horticultural System in the UK is a real approach that:

• Aims to produce fertile soils and nutrient-rich crops without synthetic fertilisers, herbicides or pesticides. 
• Uses biological composting and soil life (fungi & bacteria) to build fertility. 
• Has been applied on marginal or depleted land by some growers with positive results. 

But it is not extensively validated through independent scientific trials at the level of mainstream agricultural research. Claims about complete elimination of weeds or pests without any management are not universally established beyond anecdotal or organisational reporting.

OUR GOAL IS TO GET THIS SCIENTIFICALLY VERIFIED.
