Which medium to use for my seedlings?
KISS rules with seed. Simple potting soil mix, no extra ferts or amendments, 3.5 inch square pots in a prop tray. No dome usually unless its too warm and dry to maintain a moist substrate for 24 hours. Spray mist with plain water to til the sprouts pop and shed seed coats, then gentle watering with plain water til second set of true leaves.
Seeds need: 1) lightweight, moist not soaked, soil 2) warmth, from 75-85F; 3) veg-level light from the day they break soil 4) some air movement, which is why I usually don't use a dome.
That's it folks. All the rest is folklore, that at best won't hurt anything but at worst will stunt or kill your seedlings. I cringe at some of the techs I see on the boards, paper towels, kelp teas, peroxide, peat pots (!), floating in a glass of water, point up, point down, etc., etc. These techs are for the benefit of anxious humans who can't wait 3 or 4 days for their bean$ to sit out of sight underground, doing what seeds are designed to do. Seedlings just want warmth, water, soil and light.
