Our Custom 14' x 26' Greenhouse

As we were assembling our 10' x 26' Planta greenhouse, we came to the conclusion that by if we purchased our own twinwall polycarbonate, we could design and build a wood frame greenhouse of the size that we wanted. Twin wall polycarbonate is not inexpensive and 1/3 of the cost in getting it is freight shipping. Rather than get just what we needed, we opted to go with a 200 sheet purchase which shipped on 2 4'x8' pallets which required a feight dock. This provides us the opportunity to help others get started with their own greenhouse or lean-to.

As can be seen, the structure is completely sealed to keep in warmth on cold days along with ventilators along the roof to keep conditions bearable in Summer months. Without the ventilators, the temperature can easily hit 120 degrees.

About the time that we started construction of the greenhouse, we had also started seedlings in the Planta 26. Once the new greenhouse was mostly framed in, we moved most of the tomatos in and let them go.

As can be seen in these pictures, late in the Summer, we had some that were well over 8' tall!

This is what is involved in building a greenhouse from scratch. From a solid footing to bracing walls during the construction, a single person can do it; however, having an extra pair of hands around certainly helps.
