PyGrow
PyGrow® as a Biostimulant

PyGrow is a liquid biostimulant that significantly up-regulates photosynthesis, giving more energy to the plant-microbe ecosystem that increases plant health, mineral- and phytonutrient content. It very economically increases the vigour and productive yield of agricultural plants and trees, while enriching soil carbon content.

Our precise thermal decomposition technology produces a unique extract from the biomass we process that we call PyGrow. It is similar to pyroligneous acid or wood vinegar, except that our process ensures that:

  1. it is optimised as a plant biostimulant to significantly increase productivity
  2. it is consistently and reliably produced
  3. it is completely free of any contaminants that sometimes are present in wood vinegar produced in the traditional way.

PyGrow belongs to the same family as pyroligneous acid (PA), whose biostimulant effects are well documented, but it is produced by a distinct precision process. PA, as conventionally made, is a byproduct of making charcoal. The pyrolysis process conditions that produce charcoal also generate tars, oils and heavy phenols in the condensate, which are toxic to plants and need to be removed using a lengthy distillation process if PA is to be used as a biostimulant. Poorly controlled pyrolysis and distillation process variations combine to make PA highly variable across producers and batches. Some plants are more sensitive to these variations than others. So while research has demonstrated that PA increases productive yield significantly, an average of 31% at optimal application rates in this study, PA use has not gained traction because of its unreliable and cumbersome method of manufacture.

PyGrow

Our patented, highly efficient biomass extraction process is designed to precisely and reliably capture only beneficial compounds, so every batch of PyGrow is consistent, guaranteed free of any toxic compounds, and optimised as a plant biostimulant.

All plant life today evolved from ancestors that were exposed to countless wildfires over 800 million years. These wildfires were likely very frequent in periods when our world was hotter than it is today. The species that survived were the ones that responded to residues of fire in their environment by producing more seeds, to ensure the survival of the next generation. Today's plant species retain this genetic imprint, allowing us to leverage natural selection to economically and organically improve crop yields.

All plants need is a trace amount of these smoke molecules as an epigenetic signal: There's been a fire! This is exactly what PyGrow provides. They respond by upregulating photosynthesis, increasing the sugar and metabolite content in their sap, producing more foliage, flowers, fruits and therefore seeds, and also releasing more root exudates into the soil to nourish and perhaps signal the microbial community in their root zone. Elevated sugar and metabolite sap content makes them more resistant to pests and diseases.

Plant-associated microbes, which evolved along with plants under fire stress and are dependent on them, get busy fixing nitrogen and making bound mineral nutrients plant-available. It would not be surprising to learn one day that plants are passing this signal on to their microbial community: There's been a fire! We need specifically these soluble nutrients so I can make more seeds and we can survive. Evidence, in the form of productivity increases (which require plant nutrients) and elevated soil organic matter, seems to suggest that this is an all hands on deck community effort. See our summary of a review paper that we sponsored: Pyroligneous Acid Significantly Increases Crop Yields and Biomass Growth.

PyGrow can support the transition to regenerative agriculture by allowing growers to optimise yields at lower cost, reducing the need for chemical inputs, while increasing soil carbon content and soil health. It is fundamentally an organic product, and should be certifiable as such in most areas of the world.

PyGrow as a Chelation Agent

PyGrow contains a variety of organic acids, primarily acetic acid among others. It can therefore serve a dual function, both as an epigenetic signalling substance and a chelation agent to make mineral nutrients easily plant-available. Consider combining diluted PyGrow with any essential macro and micronutrients that may be needed to support photosynthesis, fruit, vegetable or grain optimisation, disease resistance, etc. Our in-house trial experience suggests that this can be the most effective way to use PyGrow.
