Note: This calculator is meant to be used only as a general guide.Several factors may drastically change cooling BTU needs including, but not limited to:high ceilings, poor insulation, ambient outdoor temperature and lamp type/shape.

For more help on calculating recommended BTUs based on specific grow room factors, please call 1-877-9-IDEAL-1.

As a general rule, we recommend using more versus less BTUs of air conditioning. If you are uncertain about themodel appropriate for your application or are in between models, always size up. Your system will not have to workas hard and will run more efficiently!
