@AsNoriu, Thank you for the warning! I certainly can see how a high-powered light could generate enough heat and boil the seedling, but in my case I'm only using a 20W LED light so I doubt it will be a problem. Nonetheless, I will keep an eye on them so thanks again for the warning.
I actually have proper humidity domes but they are all too large to fit on these small pots. I'm only using these glass domes temporarily and will go out tomorrow and buy some plastic cups and simply drill a couple of holes for a bit of air-circulation. I will move the seedlings into their tent in a few days, and I will start using my real humidity domes once the seedlings come under a proper light.
