The dosing rate of Worm Power is actually based on a set volume per plant per week without regard for EC or pH. The rationale behind these volume based rates is that Worm Power is much more than simple fertility. When you make use of our product you will be delivering a host of microbial actors to the root zone. These living organisms will populate the media surrounding the plants’ roots, as well as the roots themselves and must be delivered in quantities that are appropriate to each crop and container size.
