A hoop house or cloche is a tunnel made of plastic, usually semi-circular, square or elongated in shape. The interior heats up from the sun and warms the plants and soil inside, keeping your plants nice and cozy over the colder months.
Instructions for your DIY hoop house for a wooden garden bed frame
3 ten foot 1/2 inch diameter pvc pipe for the hoops
1 one inch diameter pac pipe for the hoop holders
12 one inch pipe straps
screws to secure straps to wood
10 foot by 25 foot heavy-duty opaque builder’s plastic
12 inches of self adhering velcro.
8 foot lath strip (thin wood strip) cut into eight 1 foot lengths
Tools needed include a vise grip, reciprocating saw, drill, scissors, hammer
STEP ONE: Cutting the materials.Cut the 10 foot 1/2 inch pipes to 9 foot.
Cut the 1 inch diameter pipe into 8 six inch long sections.
Cut lath strip into 8 twelve inch lengths,
Cut rings about 1/2 inch wide from the remaining 1/2 pipe.
Cut 1/4 section from each ring leaving clips to hold the plastic on the hoops at each end.
STEP TWO: Secure the hoop holders.
Attach the 1 inch pipe lengths to the side of the wood frame with the pipe straps.
Use two straps on each pipe. Measure and attach the straps to the wood with with 1 1/2 inch wood screws so that the hoop holders line up on each side of the wood frame.
STEP THREE: Assemble the structure.
Insert one end of the 1/2 inch plastic pipe in the 1 inch pipe holder, bend it across to the other side and insert the other end in the holder on the other side.
STEP FOUR: Cut and attach the plastic covering at each end.
Cut 8 foot of the builder’s plastic for an 8 × 10 section and cut this in half.
Attach one of the plastic halves to each of the hoops at the end, securing the plastic with the plastic clips you made. Take your time. This takes a little muscle and you don’t want to rip the plastic.
Once the plastic is attached, cut off the excess to about 4 inches from the frame
STEP FIVE: Prepare and attach the center plastic cover.
Cut a piece from the remaining plastic that is 24 inches longer than the bed the plastic will cover. Drape the plastic over the hoops and line it up to fall evenly.
Fold the plastic back from the middle and attach 4 inches pieces of self fastening velcro to the very top of each hoop.
Peel off the protective paper and unfold the plastic across the hoops and press firmly to adhere.
STEP SIX: Fasten the cover to the frame
Align two 1 foot sections of the lath wood and drill two holes through both pieces.
Repeat with the remaining lath strips so that there are four pairs with matching holes. Use a peg to hold one set of holes in exact alignment while you drill the second set.
On the bottom of each flap attach the lath strip to the plastic in pairs between the middle and end hoops, two on each side. Roll up the plastic and lath pieces and staple together.
Nail finishing nails through the aligned holes in the lath strips into the wood frame for all four sections.
Once all the lath has been secured, wiggle the lath strips and plastic pieces free of the nail so that the plastic cover can be lifted from either side and then refastened when necessary.
