Here is a list of some of the materials that we do not supply, but you most likely will need to complete your build.
Ground stakes / posts
2x6 Lumber- enough to go all around the base of your greenhouses. This will be used to create what we call the “base frame”.
2x4 Lumber- enough to span the length of your greenhouses on each of the long sides. This will create your “hip board”.
2x4 lumber- enough to frame out your end walls. End walls range from very simple to framed out like a wall in your house. Please look at pictures on our site for some end wall inspiration.
4x4 posts- you will need 2 for each end you plan to put a door in.
Doors- screen doors make excellent “man” doors. if you would like a larger door, building one out of 2x4 is also an option.
3” Deck screws- enough to screw together your end walls.
Concrete- (1) 60lbs bag of concrete per ground stake. You can also just pound the ground stakes into the earth, but concrete is recommended.
2’-3’ stakes used with a string-line to establish the perimeter of you greenhouses in the beginning.
