Coolaroo Grow Bags create a lightweight, breathable environment for your plants to grow faster and larger. Our durable, knitted fabric allows air to penetrate the soil, automatically pruning the roots and causing the plant to sprout more roots. This leads to thicker, more fibrous roots and a healthier plant, accelerating growth and increasing plant yields. The breathable fabric increases drainage and aeration to guard against overwatering and to regulate soil temperature, keeping the roots cooler in the summer. Our strong, reinforced handles and lightweight design make it easy to relocate your garden, indoor or outdoor, and they are collapsible for easy storage. They are also easy to clean just hose off and reuse season after season so you can enjoy these decorative planters for years to come. When using indoors, place the bag on a tray to protect surfaces from the draining water. The 100% recyclable fabric is BPA-free, phthalate-free, and lead-free.
