  1. Place the lid on your greenhouse. If it includes a humidity dial, increase the humidity by turning the knob. If you are using a to-go container, check if it has holes on the lid. If not, use a safety pin to poke holes in it to help with airflow.Did you know? You can practice conservation through gardening. Limit your water usage by collecting rainwater to water your plants, or water plants in the morning or late afternoon, instead of mid-day to avoid evaporation when the sun is highest in the sky.
  2. After you place your lid on your greenhouse, place it next to a sunny window. You may begin to see moisture inside the lid!Did you know? If you like gardening, there are so many careers out there for you! A horticulturist is a person who is an expert in growing and managing plant production. An environmental engineer works to minimize and manage hazards to the environment. There are many more jobs like these… take a look online to see what might interest you!
  3. Make sure to check everyday if the soil is moist, and water lightly if necessary. Enjoy watching the seeds grow in your mini greenhouse.Did you know? It really does take hard work to make food, and we can appreciate all the gardeners and farmers that are providing food to our table.
