A serendipitous day for seed starting, no? After you've considered everything that needs considering:
Step 1: Sanitize containers. Use a 9-parts water, 1-part bleach solution. I then rinsed the containers (I'm using old pots plants came in, yogurt cups and a mushroom container. The last 2 the handy husband punched holes in the bottom for drainage). Cleanliness is key!
Step 2: Wet the potting mix. Easy peasy.
Step 3: Write the name of the seeds & the date you're planting on a tag. Before you forget! I'm using wooden ones, but sanitized Popsicle sticks or even a toothpick with a label flag would work.
Step 4: Plant! Put you moistened soil into the container. Press it down to get out the air pockets. either spread seeds all around the container (if you're using a large one) or place 2-3 only in the pot (if you're using a smaller pot & don't plan on transplanting later). I've done both, but shown here is the latter.
(Notice the 3 little seeds in the middle?)
Step 5: Sprinkle! Sprinkle a bit of dry potting mix over you seeds. Then spray (to moisten) with a misting spray bottle. Next, sprinkle a bit of milled sphagnum moss to keep fungus at bay.
Step 6: Place pots in a waterproof tray, stack and place on seed warming mat. I've got 2 trays, so I covered them in plastic wrap & stacked them so that I just need one mat. At the seed starting class I took, the instructor assured us this would work. Instead of plastic wrap, you could use any vegetable plastic bags (the kind you get from the grocery store for separating produce) on single post.
Another method to starting seeds that works well for peppers, eggplant, tomatoes, & anything of that family is this damp-paper-towel-sushi-in-a-plastic-bag method.
Step 1: Damp paper towel. Fold into quarters, and sprinkle on seeds. Don't forget to label!(Sorry for the poor photo!)
Step 3: Wait. When seedlings emerge, transplant into pots similar to the process of Method One, Step 4. Notice that I still put the paper-towel-sushi-in-a-bag on the heated trays.
