Selecting a Greenhouse Site
The greenhouse should be situated so it is easily accessible.
Experts recommend that the ridge of the greenhouse run east to west. During the winter months, this angle provides maximum light transmission.
For dormant or resting plants a minimum of six hours of light is required.
Growlights can be installed to supplement light requirements for the greenhouse.
Greenhouse Site Preparations and Foundation
When selecting a site for your foundation, a flat, level surface is essential so that the greenhouse can be easily installed, stable and secure. Locate your greenhouse close to power and water, while also considering water drainage and easy access. Try to locate the greenhouse so that 6 hours of sunlight is available during the winter months.
Whatever your choice of material for the foundation, the base must be level and square, and built to the exact outside dimensions of the greenhouse. (A foundation sketch will be provided.)
If you will be having raised foundation, lowering the door to ground level is a free option. This is called a door drop. The opening to leave for the door will be noted on your sketch and this dimension must be confirmed upon order.
The most economical foundation is Rion’s specifically developed base, and we feel it is your best option. This base is made of heavy-duty plastic with a honeycomb like design and it is closed U-shaped. When the base is filled with dirt, it will not move (nor will the greenhouse), and no other stakes etc. are necessary. Other option is a row or two of 4 x 4 timbers (or 6×6’s for larger greenhouses). If possible, concrete blocks in the corners will also help to keep the timbers from eroding. Other foundation options include a concrete slabs or a raised concrete wall. The higher a foundation is raised, the more head room becomes available inside the greenhouse for hanging baskets and tall plants.
