Step 1: Tools
1. Pots (3 pots at $0.78/pot=$2.34)
2. Seeds (3 packets at $1.34/packet=$4.02)
3. Potting soil (One 4-quart bag at $2.00/bag)
4. String ($1.39)
5. A tray or plate that is non-permeable to hold the pots and water ($7.19)
I spent $16.94. Depending on how much you value aesthetics, you could spend more or less. For instance, you could use clean cottage cheese or yogurt containers with a hole in the bottom instead of a pot, or you could buy actual pot trays to match the pot instead of a plate. Three pot trays would be about half the price of the plate.
Step 2: Prepare String
Step 3: Soak String
Step 4: Set String in Pot
Step 5: Fill Pots With Potting Soil
Add water and mix until that the soil is evenly moist.
Step 6: Plant Seeds
Put a few seeds from each packet in the center of its own pot. Follow the directions on the seed packet to know how many seeds to plant. On some packets, directions will say to "sow seeds thinly." I interpret "thin" as about four seeds. If directions do not explicitly state how to plant the seeds, I plant no more than ten seeds.
Step 7: Cover Seeds
Step 8: Water Soil
Step 9: Fill Tray
Step 10: A Few Last Tips
1. Before seeds begin to sprout, cover the pots loosely with plastic wrap to retain moisture. Cover loosely so air can still get to the soil.
2. Keep the plants somewhere warm like above a refrigerator until seeds sprout. When they sprout, move the plants to your window sill where they will receive sunlight, and also remove the plastic wrap.
3. Remember to water the tray as needed to keep the water level above the bottom of the pots. Also occasionally monitor the surface of the soil to make sure it does not dry out.
