I bought a package of these cheap plastic lunch boxes from Walmart. They are perfect for starting seeds with rock wool cubes.
I was going to throw away a packet of Beef Steak tomato seeds that didn't sprout in my first attempt, but I decided to pour it into a petri dish instead to see if any sprout and I see a few sprouting. I will transfer them into rock wool cubes when I see the white tail come out of the seed. All I need is one or two to survive and then I can clone the plants.
I only use the petri dish if they don't sprout in a rock wool cube on the first attempt.
