F2 seeds are simply the second generation of hybrids. You really don't have to do anything special to them as they will grow just as any other seed. Of course, seeds need specific requirements to germinate so you will need to know a little about the parent plant. Assuming that all the requirements for germination have been met, such as stratification and scarification, this is how to plant your seeds.
Plant the seeds into the potting soil about twice as deep as they are thick, as a general rule of thumb. Press the soil into place over them making sure they have good contact with the soil. Water the top of the soil gently, making sure not to uncover the seeds, especially if they are small.
Set the pot or tray in an environment suitable for the type of seeds you are growing. Some plants need a steady heat of about 65 to 70 degrees, while others do fine in 40 to 50 degrees. None really need sunlight until they have sprouted out of the soil. Most will need to be kept moist at the same time.
Give the seedlings enough light so that they don't grow too leggy. Most plant lights can be positioned about 6 inches from the tops of the plants. Let them grow until they have a couple of sets of leaves.
Transplant the seedlings to their permanent home, whether that is a larger pot or a spot outside. They should continue to grow as normal, portraying characteristics from their parent plants and the previous generation.
