Hello everyone!
My tip for seed and indoor bulb starting is one I've been using for years. Very inexpensive as well. I use 12 or 16 oz. styrofoam cups to start anything that needs room, or extra growing time, before it gets planted out. Just cut slits about 2" long from the bottom of the cups upward in about 3 places for drainage. Fill er up with sterile mix and plant. When it's time to transplant, just peel away the bottom half of the cup and place your plant, no root disturbance problems and you can "hold over" the plant for a longer amount of time if necessary.
I even have success with this method for items most folks say you can't transplant due to transplant shock. Like moonflowers. I'd never have a moonflower bloom if I could not start them early.
