Constructing a Hoop House Greenhouse

For the month of December
I have a greenhouse business that sells bedding plants, veggie plants,  hanging baskets, and small planters.
I have to construct a new hoop house  that has a germination chamber.  The hoop house will only be 12ft X 40ft.
The height in the center is only 6 1/2 ft high.  This hoop house is called the  Seedling House. The germination chamber is a long mini greenhouse inside the hoop house  with heating mats and electric heaters.  After the seeds have germinated and had a chance to grow a few weeks,  they are moved out of the germination chamber  into the bigger portion of the hoop house and grown there until it is time to transplant  in the large greenhouse. (20x96)
Construction starts this week.  At first it is slow going cause we have to prepare the area and lay out commercial ground cover,  measure and set up ground stakes for the hoops to be attached to.  Then set the hoops and set the perlin.  The perlin is just a galvanized chain link fence top railing that is attached to the top of the hoops with galvanized U brackets  which keeps all the hoops in place.  There is actually a lot of hardware detail to constructing the hoop house and there will be a lot of photos posted.
I don't think I can complete the hoop house exactly the way I want it done  right now, but I can work on it and get it operational enough to get my germination chamber up and running.  I would like for the hoop house to have  manual  side curtains that can be raised when temps rise high in the early spring but I might have to wait on those details.   I have to sow seeds the last week of December.  Income is always limited between December and March.  It takes a lot to get the main greenhouse up and running.  My brain is scrambled.
So hang tight,  construction and pics start soon.


I made the hoop house shorter.....but wider 16x24
with a mini hoop inside for germinating seeds early.
double protection.











These little pvc clamps hold my poly onto the   Mini pvc hoops.
The  mini pvc hoops are just slid over a iron rod driven into the ground..
Since it is inside a larger hoop house,  there was no need to anchor it down.
