Additional Information
How do I size my fan and shutters system?
- The first thing that you need to determine is the amount of air required. This is stated in CFM (Cubic Feet of Air per Minute).
- Use the following formula to determine the CFM required for your greenhouse:
CFM = Length x Width x 12
Example: Greenhouse 12' wide and 24' long requires 3456 CFM (12 x 24 x 12) - Reference the above table. Select the appropriate combination of fan(s) to achieve the necessary CFM rating. Be sure to match the total CFM output for your exhaust fan(s) to the CFM ratings for your Inlet Shutters.

Not the best quality
Color: Rustic Brown, Size: 35 Inch, Style: 2 Pack, Color: Rustic Brown, Size: 35 Inch, Style: 2 Pack
The shelving unit was not as I had expected. It arrived damaged. The damage is on the under side though. They are hollow and not hardwood as I had expected. Save your money if you want something of good quality. These are like 3 pieces of pressed wood glued together. They are space saving and look great in my space. The mounting hardware it comes with was plenty enough to hang these but make sure you hang them in the studs if at all possible. Assembly was simple. It does come with a micro level. Which a kid or pet could accidentally swallow. It’s like pill capsule sized so just be careful when opening the package.
