FAQ

Because our structures are modular pretty much any length is possible, however typically shorter than 48 ft long is not practical.

There is no maximum length from a structural point of view. Material handling factors play a more important role in determining how long you want your greenhouse.

Absolutely. On all our coldframes, high tunnels, and greenhouses, you can add to the length at any time. Our gutter connected greenhouses are designed to be able to add houses to either side as well.

Natural ventilation uses rollup sides, roof vents and side vents to allow air movement to flow naturally through your greenhouse giving you greater control over your greenhouse temperature. By using natural air and air movement to cool your greenhouse, your crop will respond beautifully. Natural ventilation is less expensive to use on a daily basis. A fan/shutter set up is beneficial primarily during winter months where natural ventilation on your greenhouse is not possible due to its design. A fan/shutter system however can be beneficial as a supplement to your natural ventilation during winter months when it is not practical to use your natural ventilation. There is a greater day to day operating cost using fan/shutters. To see which design will work best for you, a GGS sales rep will be happy to discuss this with you.

Yes we do. GGS can install your coldframe or freestanding greenhouse on an hourly rate.

Yes we can. If the greenhouse was made by others, it will be necessary to provide the name of the manufacturer in case specific parts are required.

The most common roof covers are double inflated poly and glass. You can also cover with 8mm PCSS, Acrylic, and sheet metal in some applications. To find out which option is best for you, a GGS sales rep will be happy to discuss this with you.

3mm glass gives the most natural and best light transmission resulting in beautiful, healthy crop. Glass maintains its clarity for many years and is generally low maintenance. 8mm PCSS is a polycarbonate structured sheet, and is a less expensive alternative to glass. However, the light transmission is not as high and the product has an approximate life span of 10 years. 8mm PCSS can be a challenge in higher snow load areas as well. Acrylic is a little more expensive but is a natural UV protected product so it does not yellow over time like polycarbonate does. To find out which option is best for you, contact GGS and a sales rep will be happy to sit with you and help you decide.

GGS offers flexible payment terms. Your sales rep will discuss the details with you.

No you don’t. In fact, in some cases you cannot if you do not have electrical service to your greenhouse. However, if you have this capability, GGS strongly recommends that you do. Inflating your poly extends the life of your poly and provides insulation during cooler temperatures.

Yes we can. A GGS sales rep will be happy to work with you on special size greenhouses.
