Dalen Gardeneer Plant Protectors

The protectors feature water-filled chambers that act as a thermal battery. They absorb solar heat throughout the day and slowly release that warmth at night, creating a stable microclimate that protects your plants against temperatures as low as 16°F.

While the red-tinted film is specifically engineered to boost tomato growth and yield, you can certainly use them for other cold-sensitive crops like peppers or eggplants. The thermal protection benefits apply to any plant that fits within the 18-inch diameter.

These protectors are designed to extend your growing season by up to six weeks. This allows you to get your seedlings in the ground earlier in the spring and keep them producing well into the cooler autumn months.

They are built from heavy-duty plastic designed for multiple seasons of use. Once the frost season passes, you can simply drain the water, clean them, and collapse them to store flat until you need them again.

Setup is straightforward. You simply arrange the protector around your plant, fill the chambers with water to create the structure, and ensure the top is positioned to allow for proper airflow and growth.
