Small Cold Frame Inside the Larger One
Despite having the large cold frame there is also the small sized one on the inside. This structure is made from PVC pipes and measures about 5ft wide and 9ft long and is about 4ft tall at the peak. It is covered in a single layer of 6mil clear polyethylene just like the larger structure.
Grower may wonder why have a small cold frame when there is the larger one already in place? Well, the reason is to reduce the size of the area that needs to be heated. This smaller area is easier to warm up and with the nights of March being quite cold reducing the heating area offers energy savings. There are multiple nights of frost/freeze conditions so this smaller area can still be maintained around 75F despite the below freezing temperatures outside.
Heat is added to the small structure via multiple 100watt ceramic Reptile heat lamps that generate no light but do produce heat for the plant. The reason for the no light is so the photo-period can be dialed in without giving the plants 24-hours of light when all they need at night is heat.
