March is an interesting month here in Northwest Oregon. Brilliant sun one moment, drenching rains the next and then for a little variety sometimes you get both at the same time! Lucky for us we recently had a run of several beautiful dry days in a row so back to the hoophouse project we went.
Picking up where we left off we began by installing bracing on the sidewalls at each of the four corners. Diagonal braces run from the bottoms of the outside bow, past the 2nd wall post and down to the sill board. With each addition the structure gets more & more rigid. With that mission accomplished we turned to constructing the end wall frames. First posts were set vertically into concrete on each side of the door openings and then fastened to the bows at their tops. After letting the concrete set for a day, the top of each post was cut off, with an angle grinder, to the same height as the top of the bow. The rough edges of the cuts were then ground smooth to minimize any chance of catching & ripping the poly covering when it is later pulled into place. Horizontal pipes were then installed on each side of the doorway opening at sill & shoulder level. Once installed the ends of those pipes were cut off plumb at each side of the doorway allowing enough room to center the door frame in the opening. The door frame sides then slipped over the ends of the pipes and were screwed into place, with the sides plumb, the tops level and the bottoms at finished grade level. On the final evening before the rains returned we were able to hang the frames of the doors in place. You can follow the process in the pictures below.
When next the weather cooperates we will move on to installing louvered intake shutters on each side of the door on one end and an exhaust fan on the gable above the door at the other end. Lastly we will install sill boards at the base of the end walls and then install the channels that will ultimately hold the poly covering in place. At that point the frame should be complete.
We are so close to pulling the cover on… which is a good thing as I am quickly running out of room for flats of seedlings under the grow lights in the house!
