Gro-Caps act like little greenhouses that protect your plant and allow you to harvest up to 30% more. A vent hole in the top provides easy watering and prevents overheating. The Gro-Cap plant cover provides a clear protective barrier from not just weather but also garden pests and chemical spray allowing you to grow your garden organically. The clear plastic cover also allows the plant to receive sunlight & greenhouse like warmth while retaining moisture to foster growth. A lip around the outside provides a sturdy anchor to the soil pushed up against it. Measuring 10" x 10" x 9" high the Gro-Cap gives your plant plenty of room to grow. At the end of the season the plant covers can be easily stacked and put away for the next season. Gro-Caps plant covers are perfect for tomatoes, lettuce, cabbage, spinach, cucumbers, zucchinis, corn, peppers, eggplant, turnips, squash, melons and many other garden vegetables, fruits and flowers. Gro-Caps are the reusable next generation of hot kaps. They are made from clear recycled plastic to provide an easy to use individual greenhouse that protects and grows your plant. Growers & Gardeners love Gro-Caps!
