Cold and Warm Weather Gardening Terrarium Starter Tray Containers

Seed Germination for Garden Planning

These terrariums are small, enclosed shelter containers used to support seed germination indoors when outdoor temperatures are cold. The terrariums are see-through structures because of the light requirements for the seeds. You plant a variety of vegetable seeds that need light reaching the seed during germination. Seed germination takes place with little or no moist soil mixture covering the seeds, or it takes place with just moist soil mixture under and around the seeds. Also, seed germination takes place when you slightly press the seeds into the moist soil mixture or slightly cover them with it. Examples of vegetable seeds include cucumbers, peppers, squashes, tomatoes, melons, and lettuces. Flower seed examples include snapdragons, petunias, begonia, poppies, and impatiens. You press the seed starter mixtures lightly over the seed to have light coming towards the planted seeds. When germinating seeds, follow seed packaging instructions when you are planting seeds indoors in terrarium units, or when you are direct sowing seeds outdoors in the garden, or when you are sowing seeds in warm weather outside in these terrarium containers. 

For seeds that require darkness to germinate, like onions or sunflowers, you cover the terrarium unit with black plastic during germination. When leaves develop, move plants to a sunlit area. 

Seedlings and Seedlings that are Transplanted (Transplants) 

In cold temperatures, keep seedlings and transplants warm and in well-lit spaces. 

Transplant seedlings from a seed starter mixture to a potting mixture into planting vessels after the true leaves have formed on the seedlings. This new soil feeds the transplants’ roots. Also feed transplants with a very diluted organic plant fertilizer. Move transplants to a greenhouse, or to a greenhouse-type setting, or to a much larger type of terrarium vessel to nurse the plants until planting the plants in a garden or in a garden container. Greenhouse-type settings are sunny, warm, and enclosed with moist environments for plants to flourish. Use a plant heat pad and extra artificial lighting when you create the greenhouse setting. 

Seedlings that are not transplanted come from seeds that were sown in an organic potting mixture in a large potting vessel, where they can survive after they had germinated, and their true leaves had formed. 

After plants are well adjusted, feed plants based on the nutritional needs needed for each type of plant sown.
