Seedlings-in-a-Toilet-Paper-Tube. Cut the tube in half, squish it flat, then open and squish it flat again so you have a 4-sided tube. Cut 1/4th the way up the tube and fold in the bottom. Perfect for small transplants. Put them together inside a recycled plastic container- I am using the plastic containers that spinach and salad come in. The ones from Costco are big enough for a bunch of these.
Homemade "Miracle Grow": Get a clean glass jar, put a little water in it. Add egg shells and coffee grounds until it's about 3/4 full. Top it off w/water and allow to sit in a cool, dark place for about a week, gently shaking once daily. Strain pop the discarded shells and coffee grounds in the bonrashi and use the liquid when ready to feed plants.
