FibreDust Berry Blend Grow Bags feature a proprietary blend of coconut coir. Each bag measures 1 meter (approximately 3 feet) in length. These OMRI-listed bags have a natural pH of 5.5 to 6.5 with electrical conductivity (EC) levels below 0.8. FibreDust designs their Berry Blend Coir Grow Bags for moisture retention. These bags meet all the needs of strawberry substrates. The heavy pith blend delivers the moisture that berries need to grow without becoming soggy. You can install these lay flat bags nearly anywhere. They work well on the ground, suspended in gutters or troughs, or on elevated table tops. Placing these bags on a proper slope is critical during installation. Orienting the bags at a 1-1/2% slope allows for proper irrigation and runoff collection. Once hydrated, the coconut coir fills the bag. Once filled, the bag is ready for planting. FibreDust engineered their Berry Blend Coir Grow Bags to retain more than a day?s worth of moisture. Their unique design retains this moisture while preventing over-saturation of your plants. This process fosters extreme root growth, leading to healthier and more productive plants!
