I am going to germ and put my seeds in the soil all in my closet and am wondering once the seedlings sprout should i immediatly get them some light? and when there in the cups before they sprout and once they sprout i am going to have a plastic bag on them to keep it humid,when should i take that off because i am planning to grow them in that cup outside my house somewhere and then when there big enough put them in my actual grow site.
