Hello everyone, it's taken a bit of time, but I think I understand how winter sowing is accomplished and why. I would like to give it a try this winter. The thing that puts me off the idea is saving, cutting, taping and moving around jugs. Do the same principles apply using a cold frame.
Can I just sow in regular pots and put in the cold frame? I've never used one and I'm wondering if it's worth the effort to build.
WS in vented containers is very much the same principle as using a cold frame, but you'll have to do your own watering in a cold frame (rain usually provides enough water for WS containers, at least until it starts heating up). Just as people talk about increasing the size of the vents or taking tops off WS containers as it gets warm, you'll want to be able to prop up an end up your cold frame cover for ventilation so it doesn't get broiling hot on sunny, warmer days.
You could also consider getting some clear plastic storage containers, putting holes in the top for ventilation and holes in the bottom for drainage, and then putting pots of seeds inside... I can't remember offhand who did this (very successfully) last year, but I thought it was a good idea.
Since this will be my first year to try WS, I may use the hay bale or large clear container, both great ideas. As I put together my seed list this Summer I'm sure to have lots of questions. Thank you so much for the info.
