Diatomaceous earth is used as an insecticide, due to its abrasive and physico-sorptive properties. The fine powder absorbs lipids from the waxy outer layer of insects’ exoskeletons, causing them to dehydrate. Arthropods die as a result of the water pressure deficiency, based on Fick’s law of diffusion. This also works against gastropods and is commonly employed in gardening to defeat slugs. However, since slugs inhabit humid environments, efficacy is very low. It is sometimes mixed with an attractant or other additives to increase its effectiveness. Diatomaceous earth is also a good source of silica containing around 80%.
Micro Calcium A raw calcitic lime micronized to a 2 micron particle size. The ultra fine grade allows it to
Micronised Gypsum A raw gypsum micronized to a 200 micron particle size. The fine grade allows it to easily fall into suspension when mixed with water. Uses To add calcium and sulphur as a supplement or where a deficiency has been observed. Directions for use Use once a week at 2.5 – 5ml per litre of water to supplement calcium and sulphur. To fix sulphur deficiencies use 5ml per litre of water and adjust pH with a fermented/acidic product such as the Cannabis Microbial Consortium or Micro Calcium. Apply twice a week until deficiency has been rectified. Be sure to keep the water moving/agitated during application to ensure the product remains evenly mixed.
