Very common in the trades, or at least with everyone I worked with, we’d have periods where we had a shutdown usually lasting 2weeks but upto 3 months. We’d work 12-16 hour days 7 days a week (sometimes taking the 14th day off, sometimes not). A lot of my coworkers would go tax exempt during these shutdowns then switch back to normal afterwards.
Shade cloths are for hot seasons, hence “shade” in the name. They protect your crops from the sun and can help with pest damage as well. They come in a variety of different shades depending on how much light you want to let through. You can use them during the cold seasons but there are better products that are specific to those seasons, such as cloths that don’t block much sun but hold the heat in.
