BaleBuster4 – is our proprietary refined NPK (nitrogen phosphorus potassium) bale conditioning formula also containing trichoderma reesei fungi, and bacillus subtilis bacteria, which are safe for users and pets. We have packaged BaleBuster4 in the perfect quantity for preparation of four bales, and includes enough material for season long application. The gardener only needs to provide the four bales of straw or hay and water. Position bales in a sunny location, since vegetables love the sunshine. Start the preparation of bales as early as 20 days prior to your AVERAGE last frost, or anytime after. Bales are ready to plant in approximately 12 days, depending on weather. Anyone can be a great gardener by using BaleBuster4 to prepare their own Straw Bale vegetable garden.
