Frequently Asked Questions

For greenhouses that include automatic openers, such as the Janssens Victorian and Junior Victorian Greenhouses, The Hoklartherm RIGA models, the Alton models, and many others: the tube on the opener is filled with special paraffin oil - which starts to gradually expand when the temperature reaches around 72º and pushes a piston. Some of them can be adjusted to change the initial opening temperature. The piston will push the window open up to the full open position. As the temperature falls, a spring pulls the window closed. No electricity needed!

We recommend Gorilla Clear Tape. This is a high-quality crystal clear repair tape that is strong and flexible. You can find it in your local big box store. Be sure the cover is clean and dry. Use one layer of tape from the inside, one layer from the outside of the cover where any tears or splits are happening. Extend the tape a couple inches beyond the end of the split or tear.

Over time, depending on your usage, you may want to replace the cover. We offer the replacement winter covers here.

Our prices include free standard shipping (package service like UPS or FedEx on small items, curbside with liftgate on larger freight items) on all items!

In some cases with package delivery we may be able to offer expedited delivery options for an added charge, if you need your order faster. Contact us (888-648-5333, or info@mygreenhousestore.com) to ask about requesting expedited shipping and costs if needed.

Occasionally our shipping companies will require extra fees for certain unusually difficult delivery locations. In most cases, we will cover these fees as well. In some cases we may contact you for additional fees or give you the option to cancel your order.

Sometimes for especially large, heavy, or unwieldy items, or when your delivery location is not feasible for a large truck, and depending on what equipment you have available (e.g. skid loader, forklift) we may be able to offer upgraded delivery options like 'flatbed plus forklift' for an added charge.

In very rare cases with large pallets with long wood pieces (too long to rotate the pallet onto the lift gate), you may need to unload the pallet from the truck bed 'board by board' - we will always contact you to discuss this, if needed.

Some of our suppliers limit the shipping distance for some items to ensure that they arrive in great shape and to control shipping costs. For heavier items, shipping longer distances increases the chance of damage to the product during shipping.

If you will be storing some bulky items in your shed, such as motorcycles or an ATV, we recommend a shed at least 10 x 10 feet. Keeping your four wheeler out of the cold and snow in the winter is a good idea. And overall, protecting your quad from dust and bad weather will keep it in better shape, longer. A shed for your ATV can be an economical and convenient way to store it when you don't have the space in your garage.

An example might be the DuraMax Woodbridge Plus.

We are located in Atlanta, Georgia. We ship (free!) to all 48 contiguous US states.

Small: 4-7 lbs. of fresh food will fit in our small freeze dryer. That amount of food will typically fill 1.0 to 1.5 gallons (1 to 1.5 #10 cans) of food per batch. It is not uncommon for customers to freeze dry 900 lbs. of fresh food in just 1 year.

Medium: 7-10 pounds of fresh food will fit in our standard size freeze dryer. That amount of food will typically fill 1.5 to 2.5 gallons (1.5 to 2.5 #10 cans) of food per batch. It is not uncommon for customers to freeze dry 1,500 lbs. of fresh food in just 1 year.

Large: 12-16 pounds of fresh food will fit in our large freeze dryer. That amount of food will typically fill 3.5 gallons (3.5 #10 cans) of food per batch. It is not uncommon for customers to freeze dry 2,200 lbs. of fresh food in just 1 year.

Extra Large: Freeze dry 5,500 pounds of fresh food per year: 35-45 pounds per batch. In a year's time, you can freeze dry 1,400 gallons of food. Each batch produces 8-12 gallons of freeze dried food.

As a basic rule of thumb, typical snow weighs approximately 15 pounds per cubic foot, or 1.25 pounds per inch of depth.

Depending on moisture content and compaction, a cubic foot of snow can weigh from as little as 5-7 pounds for dry light fluffy snow, to 12-16 pounds for fresh wet snow, to 20 pounds or more for drifted compacted snow. NOTE: Any ice build-up on the roof would need to be added to these weights.

In some cases you may be able to brace the roof of your shed if needed, with e.g. 2x4's cut to support the roof ridge.

We recommend removing snow from your shed roof immediately, rather than waiting for it to build up. You should check and remove snow at least daily as needed during the snow season.

Polycarbonate, also sometimes known as Lexan, is a particular group of thermoplastic polymers that has many superior features in comparison with glass as well as with other polymers such as acrylic (Plexiglass). For example, it is half the weight and 250 times stronger than typical glass, making it impact resistant and virtually unbreakable.

Key Advantages:

• Polycarbonate panels are virtually unbreakable, making the material safer for applications where children or the elderly are involved, and highly resistant to vandalism or accidental breakage.
• Polycarbonate can be flame/fire resistant and self-extinguishing, producing minimal smoke or flaming droplets.
• Long service life and fully recyclable at end of life.
• Excellent heat retention creating an optimal greenhouse microclimate.
• Lightweight, making assembly and relocation much easier.
• Easy to machine, saw, drill, glue, and polish without melting.
• High optical clarity while blocking 99%+ of harmful UV rays.

Disadvantages:

• Not scratch-proof (though it can be polished to buff out light abrasions).
• Expands 0.065 mm per meter per °C, requiring flexible sealants and adequately sized channels/mounting holes.
• Can yellow over extended decades of intense UV exposure if unsealed.

LTL freight shipments are delivered via "curbside delivery." The carrier will deliver the pallet(s) to your curbside (generally the end of your driveway or entry). The carrier is not responsible for bringing the pallet up the driveway, inside, or to the backyard.

For large heavy shipments, you should be prepared to unband the pallet and move individual components as needed. You may be able to coordinate upgraded services (such as inside delivery) directly with the carrier at your own expense.

Part of keeping costs low to bring you the best prices is minimizing shipping distances on heavy structures. By selecting your region on the product page, we display accurate warehouse inventory nearest you, minimizing shipping transit times and preventing freight damage.
