How do you make a greenhouse out of egg cartons?

You can create a mini greenhouse using egg cartons by filling the egg cups with soil, planting seeds, watering them, and using the carton as a small greenhouse structure. Here's a step-by-step guide:

Steps to Creating an Egg Carton Greenhouse

Here's how to transform your empty egg cartons into miniature greenhouses, following the steps provided in the reference:

1. Prepare the Egg Cups:

   • Fill each empty egg cup with soil. This creates a small container for each seed.

2. Plant the Seeds:

   • Drop a seed into each soil-filled egg cup.
   • Cover the seed with a small pinch of additional soil.

3. Water the Seeds:

   • Water each seed gently.
   • A spray bottle works best to avoid overwatering and disturbing the soil and seeds.

4. Labeling the Seeds

   • Use a permanent marker to write the name of the seed on a halved popsicle stick.
   • Place the labeled popsicle stick near the corresponding egg cup.

5. Greenhouse Setup:

• Close the egg carton lid.
• Place the closed egg carton on a sunny windowsill. The transparent or semi-transparent lid will help retain moisture and create a warm environment, perfect for seed germination.

Benefits of Using Egg Cartons as Greenhouses

• Eco-Friendly: Reuses materials that would otherwise be discarded.
• Cost-Effective: Reduces the cost of starting a garden, since you reuse egg cartons.
• Compact: Saves space, ideal for small gardens or indoors.
• Easy Transplanting: Once seedlings are ready, you can plant the individual egg cups directly into the soil (if the egg carton is made of biodegradable material) by cutting away the top portion, minimizing root disturbance.
