An example, I put pro~mix in the butter tub, watered the mix till run off, planted a non germinated seed about 1/2" below and covered. Broke surface after 5 days on May 1st. I haven't watered as of today. Here's how it looks.
I haven't ever grown a plant that the cotyledon didn't yellow dry up and fall off eventually but not that young I should have asked for pics first. I didn't know they were so young and most over watered plants attract fungus gnats, they lay their eggs in the moist soil and the larvae can cause root damage as they hunt for food. Letting them dry a bit between watering is a key to keeping them under control and it helps the roots in two ways it lets them get oxygen and to grow and search for water toward the bottom of the pot.
Lol, yes. Before I planted i ran my pruning shears through the plastic making kind of an "airpot". The mix I use works best with a lot of airflow to it through holes, so I even put vertical slits up the sides of my solo cups to get airflow inside. Helps also with drying out the mix faster and helps the roots develop.
You can see a slit in the clear solo cup I taped up to make it dark for the roots.
Now is a good time to practice the lift method of when to water. Pick them up a few times a day and get a feel for the water weight. It'll get real light before you water again. You will pick it up one morning and go damn! it's time to water. It'll be that light. Another advantage of cutting slits in the solo cup is you can peak in and see if the sides are dry. Also the bigger container won't need water at the same time as the cups. That one will probably go at least double the time before watering.
