Dig this: Fossilized remains of long-dead critters can lend new life to your cannabis plants. We’re talking about diatomaceous earth (DE), the fossilized remains of phytoplankton or diatom algae. When they were alive, these freshwater organisms extracted nourishment from the water as it passed through their porous, silica-based exteriors. As they died, they sank to the sea floor and gradually created deposits. So what’s the dirt on this versatile substance and its applications in your grow room? For one thing, DE works as a natural insecticide, but that’s only half of the story. As an aggregate, DE also goes to work in the soil, boosting its water holding capacity and infiltration.
