I have just received in the mail some channel lock for fastening greenhouse coverings, from a supplier, Northern Greenhouse, in Manitoba. The package included a little personal note from the proprietor, saying he is experiencing some serious health issues.
Northern Greenhouse was our source for the woven polyfilm currently on our hoop house. We put up the hoop house October, 2017. We put on the covering very badly, in a hurry, and it has still lasted 5 years. The better one puts up a greenhouse film, tightly and with even tension, the less wear and tear on it in the wind. Eventually, sunlight makes any plastic brittle, even UV resistant plastic. Our plastic is still sound except where it has worn out due to flapping and abrasion from the wind.
We are due to replace the film this summer and I will be ordering from Northern Greenhouse again. They are a small business and very pleasant to deal with. I have never made a product endorsement before and I may never do so again, but this woven poly is an excellent Canadian developed product that, given the proprietor’s health issues, may not always be available in the future. If you are looking for a strong covering for a green house or hoop house or even an outdoor dining area or hot tub, do check out:
