Description
We have done quite a bit of research into finding a high quality, fully organic worm cast at the right price for our customers, and in Holland, we finally found it with Biobizz Worm Humus.
The quality is superb and the price is within the realms of reality unlike other UK manufacturers of worm casts. Should be used at an inclusion rate of approx. 10-15%.
Available in 40l sacks.
