Optional Accessories

Automatic Vent Opener - The mineral wax in the metal cylinder in the opener responds to an increase in outside temperature by automatically and gradually opening the vent. As the temperature cools, the vent gradually closes to reset the original position. Automatic openers are extremely convenient for maintaining the proper greenhouse temperature and preventing your plants from getting overheated on hot summer days. The automatic openers from Santa Barbara Greenhouses are designed for simple installation and work with both roof and side vents.

Santa Barbara redwood benchesBench Kit - These attractive and durable benches are made of kiln-dried California Redwood. They come in pairs to run the length of your greenhouse. The benches bolt directly into the frame for added stability and provide plenty of functional growing area for your plants.

Door Placement - The door of this lean-to greenhouse can be placed on either side of the greenhouse. If you enter the lean-to from inside your home, please select whether you want the door to be on the left or right side.

Santa Barbara Greenhouses liftgate deliveryLiftgate Delivery - The liftgate service is offered by the shipper for some orders to provide delivery off the truck to your curbside. The carrier will lower the packaged skid off the delivery truck to the ground with a forklift-type device. From there, it is ready for unpacking and moving in individual pieces to the assembly site.

As these kits are quite heavy, if you do not have a loading dock or a forklift available, the liftgate is a recommended option when available to speed up delivery. The pallet can then be opened at your curbside and each piece is lightweight enough so that they can be individually moved to the assembly site. This usually only takes about 30 minutes or less depending on how much help you have.

The liftgate is a required option when glass panels are selected due to the high weight and fragility of the crate(s). Even with the liftgate, two people are recommended to be available to receive delivery in order to expedite the offloading process.

Panels - The wall panels on the Deluxe kits can be your choice of 6mm double wall polycarbonate or 3/16" tempered glass. The roof panels will be polycarbonate with either selection.

Polycarbonate is practical for a growing greenhouse as it offers 50% more insulation than traditional single pane glass while diffusing excess sunlight in the summer. It is virtually unbreakable and provides an R value of about 1.8. The polycarbonate allows for about 90% light transmission, helping to minimize interior condensation.

Many Santa Barbara customers prefer the glass option as it is both economical compared to other premium glass greenhouses and aesthetically pleasing. It allows approximately complete light transmission while being virtually translucent. The glass is tempered to minimize any possibility of breakage or injury while still providing an R value of about 1.2.

Premium Package - Besides the greenhouse itself, the premium package adds the bench kit, a 12" motorized exhaust fan for one of the roof vents, automatic vent openers for any remaining roof vents, a thermostat, a heavy duty heater, and an automatic mist system. The automatic mist system includes a timer and solenoid valve with multiple mist nozzles that can turn on up to 8 times a day for 1 minute of water and 1/2" PVC piping. A 1/2" water line is to be supplied by the customer.

Ships In Panelized Sections - The lean-to greenhouse comes as a kit with everything designed to be assembled on site. Sections of the greenhouse can be preassembled at the factory, speeding up the final assembly process considerably.

Santa Barbara Greenhouses Shipping Information

The factory for Santa Barbara Greenhouses is in northern California. Therefore the shipping time to eastern states is a bit longer than to the rest of the country. Curbside delivery is included with every order, and the liftgate option is recommended.

Curbside delivery means that the delivery company will lower the pallet(s) off the delivery truck at the end of your driveway, though they will usually try to back the truck onto your driveway for a closer delivery. The driver is not responsible for unpacking or moving pallets to the build location.

When your greenhouse arrives from the shipper, it is recommended for the customer to have at least two people available to help move each piece in the pallet from the curb to wherever the structure will be assembled. Though the entire pallet(s) will weigh a lot, each piece is manageable by one or two people.

We will email you tracking information as soon as it is available. And when your order arrives at the shipping terminal closest to your home, the dispatcher there will call you to set up the delivery appointment, usually for the next day or whenever is convenient for you.
