Most sterile, inorganic soil media can be used for hydroponic growing. Why can’t Harvest Hero?
Harvest Hero Enhanced Perlite Mix cannot be used for hydroponic growing because the essential nutrients will become instantly soluble in the water, creating too much fertilizer availability and subsequent burning of the plant roots. However, you can use Harvest Hero’s domestically sourced perlite, vermiculite, and diatomaceous earth for your hydroponic growing needs by completing a special order request form.
