Selecting Grow Media

It is common to find propagators moving fresh cuttings into plugs for the initial stage of development. Once rooted plants are transplanted into grow blocks and then placed ontop of grow slabs to extend root zone development and access to water and nutrients. Selecting the correct substrate for your crop depends on many variables such as size, duration, density, and more.
