It's a different world. I keep my potting mix in the basement so it doesn't freeze. And at the hydroponics store it's stored inside so easily available year round. (It's stored outside at Home Depot and Lowes). But I love the change of seasons. Our weather has been perfect the last few weeks- highs in the 70s, lows around 50, with bright, sunny days.
In the past few years I've bought compressed bales of Sunshine Advanced Mix #4, 3 cu ft, which I like a lot. It's very loose and fluffy, and a lot easier to wet or re-wet than promix.
