Needing some help. I am building two movable high tunnels. The steel tubing is ordered and should be here are Monday. They are going to be 16 by 32. This is as big as they can be for the space available and for the plastic I have on hand. These 512 square feet houses are going to be used three times on two plots of garden. They will cover 3000 square feet of indoor growing space in one year.
My question is making them movable and able to stand up to the wind. I was going to make rails out of 2 by 4 or 2 by 6's. This rail would be screwed, bolted, lagged into 4 by 4 posts in the ground. I would then attach a 2 by 6 base board on the hoops and then attach a 2 by 4 on to this that will actually allow the structure to slide, with some force.
I thought about setting a 2 by 6 on the ground and using it like a sled, with the base board attached to the top of it. THis method would have a lot of friction with the soil.
I thought about using small wheels used on chainlink fence gates and a metal pipe/track on the ground.
Most of the ideas are from Coleman's books. I even thought about rounding up a whole bunch of old drill press wheels and have the structure "roll" on these. I can't make up my mind what to do? Maybe one of each?
Can anyone think of any other ways I could make these structures movable?
I will include pictures once they are done. I am hoping to get them finished by mid to late February.
Work the ground and start planting in them by early March.
I am using a Potatoes, Pickling Cucumbers and Cucumbers, and Spinach rotation in one and Broccoli, Zucchini, and Carrots in the other. Just FYI. The structure will be over the potatoes and Broccoli until early April, then the structure will move to the next location and the summer crops of cucumbers and Zucchini will be transplanted into it and then the other crops will be finished off outside. Once they are done and all residues removed, I may plant a crop scallions or green onions and then in Mid August/ late I will transplant/start a crop to over winter. When it starts to get too cold, I will move the hoop back over the other crop.
