The Auto-Vent Kit for the Snap & Grow Greenhouse (greenhouse sold separately). This system will provide neccessary ventilation even if you are not home. Here's how it works...The aluminum "arm" is filled with oil. When the oil heats up (over approximately 70 degrees), it contracts, causing the arm to open your vent automatically. When it cools down, the arm comes back down, closing the vent again. Venting your greenhouse could not be less difficult!

Merry Christmas!

Thank you for offering the Christmas Tree Stand, I just purchased the TS297WL and I appreciate the free shipping. I also appreciate the fact that my 14 foot tree will not fall over 3-5 times this year! Have a great Christmas and I am sure my friends and neighbors will be very interested where I purchased this tree stand.

I'm very pleased with ordering from your website.  I only ordered one small item and the shipping was free!  Plus my order was processed extremely fast, and I received an e-mail notifying me of shipment. I intend to shop from your website again when I have more time to browse.
