1.5 Kg Bag with 360 Gr Mycorrhiza
It's 'carbon capture technology' in your garden.
Every 1.5 kg bag of Biochar that you use will not only really, really increase the fertility your soil, but will capture 1.2 kg of Carbon for probably thousands of years.
We totally believe in Biochar, and now I mix it with all my compost, about 10% does it.
Then when I plant out I always add a dash of Mycorrhizal Fungi too, just enough to cover the spread of the roots.
