Build a clear growing-media enquiry, from compressed blocks to growbag formats. Start with your crop, irrigation system and required specification.

Describe whether you need compressed blocks, growbags or another format. Include dimensions, unit weight, required expanded volume and intended substrate blend.
State whether washed or buffered material is required. Request evidence of the proposed treatment and confirm the specification with your grower or technical adviser.
Provide your target EC and pH, units and test method. Ask for the extraction ratio and test conditions alongside results; an EC number alone is not a complete specification.
