Step 4: Germination
Keep your trays moist and warm to speed germination. Loosely fit plastic wrap over the tops of the trays, to keep water in but still allow for air circulation. Light is not required to germinate seeds.
In anywhere from 3 to 15 days, you should start to see tiny seedlings emerge.
When your seedlings are up and the first 2 leaves (cotyledon leaves) start to open, you will need to put your seedlings under a light.
Use a cheap fluorescent shop light for your seedlings. I use 4' fixtures that take 2 bulbs each. You can use regular fluorescent tubes, or ones specially made for plants. I use GE "Plant & Aquarium" tubes in my fixtures.
It's very important to keep your seedlings within 4" of the lights, preferably closer. If you keep the light too far from the seedlings, they will get very "leggy" - tall and skinny - and might collapse.
Keep the seed starting mix moist but not soggy, and water whenever the surface becomes dry to the touch (but NOT completely dry).
