Instructions
Acquire a 20-gallon (or smaller) fish tank that is free of cracks and has a removable glass lid. The 20-gallon tank is optimal space for a variety of plants to grow. Make sure that any plants you choose can grow well in an enclosed area. This information can best be found on seedling packages or by doing some simple research.
Place a layer of rocks or small gravel in the bottom of the tank. Place a layer of compost on top of the gravel. This should be 5 inches in depth so the roots of the plants have enough room to settle. If you are unsure if 5 inches will be deep enough, check the planting recommendations for the seedlings. Place the seedlings in the compost so they are at least 5 inches apart.
Pour 2 inches of water onto the compost layer. Place the water in the tank slowly so the seedlings do not become free from the compost. Place the lid on the top of the fish tank so moisture will stay in the tank and heat will better penetrate the seeds. For adequate air circulation, remove the lid from the tank at night.
Set the tank in a location where it will receive at least five hours of sunlight per day. Place the tank outdoors if you live in a warmer climate for faster and more effective results. Make sure to bring in the tank if low temperatures drop into the 50s.
