When I moved to my new home a few years ago I left my Harbour Freight 10×12 greenhouse and the nearly four extra months of growing season (two months on each side) that it provided – a not insignificant boost here in Ottawa given our frost free timeline is generally accepted as the end of May until towards the end of September.
Heavy duty corner brackets installed on the hoop house
So after making due with row covers and some very low tunnels last year I put in some medium hoop houses, that were hinged to open from the base. These worked pretty well – being able to grow taller crops and hold more than the single row hoops but were still a bargain cost and time wise compared to higher walk in hoops.
Heavy duty angle bracket
The base of these was made from 2×6 lumber – which provided strength and weight to keep things anchored down… but unfortunately in the process of opening and closing them the screwed together corners began to pull apart.
I tried reinforcing with 4×4 blocks but the forces were too much for that solution to last long. So now I’ve gone and built some extra heavy duty corner brackets from some flat steel bent up in the hydraulic press and some U steel to provide further reinforcement. With these bolted in place the frames are rock solid and should offer a great long lasting solution – even better, the cost to fabricate these at home was a fraction of what it would have cost to buy them would have been. That’s the advantage of having some solid tools… now it’s time to get everything into the ground!
