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.

Pretty
Very nice simple jewelry box. My only issue is spacing to put necklaces is a bit tight, but there is plenty of room in this little guy. I put a lighter next to it, for size comparison.

Amazing Jewelry Travel Case
I bought this jewelry case for traveling on a cruise and I absolutely LOVE IT! When I purchased it I didn’t know if it would actually fit all the jewelry I wanted to bring but this box definitely impressed me! It fit all my regular jewelry plus more bc you know us woman love to coordinate with our outfits lol the case/box is sturdy! It didn’t break or even dent throughout my travels. It comes with different pieces to help organize and separate jewelry but it is removable if needed which I had to do bc one of my necklaces is really big. The case fit perfectly in my carry on luggage and didn’t take up much room at all which helped me a lot. I got the black case and I just love how simple and sleek it looks. This is definitely a must have if you need to travel with jewelry and are concerned about things getting damaged, this case keeps them safe and it’s definitely a great value for your money!
