>> When you say 4" pots, does that mean 4" in diameter?
Yes, or for square pots, width. really, i just mean "pot them up into something bigger".
Pint tub, quart tub, Solo cup, 3" pot, 4" pot, cut-off 2 liter soda bottle ... whatever's handy but bigger than the little cells.
Sorry to hear you're busy, I have the same problem. For several years I tired to garden, getting around to most tasks a few weeks or months late. The weeds got ahead of me, and now I'm counting the years until retirement.
Seed starting can be a very satisfying hobby! Once you find a groove that's convenient for you and meets the seedlings' needs, it's relatively easy to create a SEA of helathy, happy seedlings. the problem then becomes how to give them all away.
Until you find that groove with good habits, it may take some trail and error. I recall one year when EVERY seed in three or four trays rotted or otherwise failed to emerge for me. Overwatering a mix that was too fine, mainly.
Starting small with a small number of plants was really smart.
