Super Soil

There are 66 products tagged as Super Soil

In this tag, we have collected together all of our soil amendments you can use to make your own organic Super Soil, as popularised by US growers such as Subcool and Clackamas Coot.

The idea behind Super Soil is to create a completely organic cultivation substrate that is rich in all the nutrients and minerals that a plant needs throughout its lifetime, thus only requiring the grower to irrigate with plain water (and occasionally with compost tea or seed sprout tea), disposing with the need for bottled nutrients. This has several benefits because, as well as being much better for the environment, an enriched super soil saves work at the same time as helping the grower to produce a superior quality harvest, richer in terpenes and free of heavy metals and other potentially harmful contaminants. 

Here you can find high quality products for no-till and organic gardening including base substrates, worm castings and many other natural fertilisers in dry format, enabling you to create your own bespoke soil mix for cannabis cultivation. These soil amendments also allow you to amend and revitalise the soil as necessary after each harvest, ensuring that the next cycle of plants will have access to a healthy, vibrant living soil full of micro and macro nutrients, naturally-sourced minerals and high levels of beneficial microbiology.
