Making Mealtime Meaningful: Discover how we're giving back with the 12T Cares program →

You know those clamshell containers that are used to store your takeout meals? There are probably more than a few of them laying around your house, right? If the answer to both questions is a resounding yes, you are definitely going to want to read on and learn more. While some of these containers are disposable, there are others that are meant to be reused afterward.

Turns out, these containers can easily be used as miniature greenhouses when you’re looking to start seeds indoors. All it takes is a smidgen of ingenuity to bring your true gardening skills to the forefront. Best of all, the cost of starting is extremely low.

All you need to get started are some seeds, some potting soil, and a clear plastic container with a cover. Individual or sectioned seedling cups are optional. Those who rely on these cups tend to use egg carton bottoms for best results. Wash and dry the plastic container as soon as you are getting ready to get started.

Anyone who is planning on using seedling cups inside their miniature greenhouse will want to fill them 3/4 of the way with their potting soil. The same goes for anyone who is using a larger plastic container as well. Follow the directions on the packet when the seeds are being planted and water them just enough to provide the proper amount of moisture. Spray bottles work well for misting purposes. Shut the lid once the watering is done.

The greenhouses can be stored outdoors or indoors, depending on your weather conditions. In mild conditions, the mini greenhouse should be outside during the day, in an area that receives bright sunlight. If the greenhouse needs to stay indoors, be sure to place it in a section of the home that receives plentiful amounts of natural light.

Does the soil dry out during the day? If so, add enough water to moisten the soil once again. Any greenhouse that stays outside during the day should also be brought in at night. As soon as the seedlings outgrow the lidded space, use a popsicle stick to prop the container open. Re-pot the plant once it has exceeded its horizontal space and plant in the ground after the frost dangers have passed.
