Using cold frame to grow seeds

Does anyone have experience in using a cold frame to start seeds in winter and early spring? Until recently I was winter-sowing in gallon-sized milk jugs and that worked well, but a lot of effort is required to tease apart the young seedlings with their roots intertwined so deeply that you end up losing many of the individual plants. I’d like to be able to instead sow directly into 3.5” pots while taking advantage of the same strategy of using plastic to let in solar heat to warm the seeds and seedlings on sunny days in late winter and early spring. I think that’s what polycarbonate cold frames do nicely but I have no experience with them. Thanks for any help.
