I sowed a row of carrot last week, Davy, as you describe, following your advice, was it last year? I find this method works well for me here, where the sun, when it finally arrives, can be instantly hot, and the soil dries out very quickly. But parsnips are easier in tubes, as I get the exact amount, and the ideal spacing.
Sowing seeds direct, even roots on my soil is pretty hopeless, so virtually everything has to be sown in containers and then planted out. I used to use modules but found the root crops didn't grow that well. I decided last year to try loo roll tubes for my parsnips and they did well, forming decent roots, although I omitted to thin them so were a it small and congested. This year I decided to try carrots in them too. So far so good, they have just germinated (parsnips not yet, too soon ). Only problem I have with the tubes is they can dry out before germination. Keeping them moist is the key, but not easy in recent weather.
