J&D’s design allows for more air flow and a much wider air pattern. This maximizes heat distribution and humidity control by mixing the air, from ceiling to floor - under, over and around your plants. The Green Breeze is the only fan on the market with the exclusive open front feature. Its unique design helps cut cleaning and maintenance time by 75%. Open the front, clean and close. No tools. No down time. Back to full energy efficient, high output operation. Proper circulation encourages healthy plant growth by increasing CO2 availability (required for photosynthesis), reduces disease and mildew caused by excessive moisture and eliminates over heating on hot days. Uniform Air Quality throughout. Comes with 6' cord and plug for easy installation.
