PowerFeed with Troforte (slow release) granular range relies on moisture, therefore they will be activated by rainfall and water supplied. The granules remain active from 6 – 8 weeks within the soil. They are affordable and therefore possibly best suited to large applications.
PowerFeed Controlled Release granular range relies on moisture and temperature. As many plants tend to grow as the soil temperature increases, these granules release more nutrients as they are needed. These are not suitable for all situations, so if you had winter plants/vegetables you would need to use the PowerFeed with Troforte (slow release) granular range depending on your climate.
PowerFeed Controlled Release Range is a premium product, so if treating a bulk amount of plants PowerFeed with Troforte (slow release) may be better suited.
