I want to start my vegetable seeds inside, then transplant outside when the weather warms. My question is do I moisten the soil in my 72 cell seed starter units or just add the soil and then put the seeds in and mist them? The lady in the garden center at Walmart told me to just mist them after putting them in the soil. I bought the seed starter soil. Will this be good enough or should I amend it with other things like vermiculite and peat moss?
