Select grow media for commercial use

It is common to find propagators moving fresh cuttings into plugs for the initial stage of development. Once rooted plants are transplanted into starter blocks, grow blocks, and then placed on top 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.
