Growing vegetables indoors, either as seedlings to transplant or as part of a complete indoor garden, requires having the proper container and soil, providing adequate light and moisture and maintaining the plants. Seedlings for transplant require a period of "hardening off," or time spent outdoors, before planting.Continue Reading
Small containers, pots and cell-packs are good for seedlings and smaller vegetables. Bigger plants need bigger containers and large pots. Seedlings require delicate soil that allows for the tiny roots to grow. Older and bigger plants need an indoor formula that contains the nutrients plants in the garden get naturally.
All plants need substantial light to grow and produce vegetables. Sunny windows can provide enough light for some seedlings and plants, but others need grow lights. Use a combination of both to give vegetables 16 to 18 hours of light a day. Adequate water is also required. Seedlings need moist soil, and plants indoors need more water than those outdoors. Feel the soil and examine the leaves to determine if more or less water is needed. Mist plants to provide proper humidity levels.
For seedlings you are preparing to put into the outdoor garden, place them outside in the sun for a few hours each day, increasing the time spent outside daily. Begin the "hardening off" process a few weeks before transplanting. For indoor gardens, fertilize as necessary, prune and remove dead leaves and continue to monitor light, moisture and soil conditions.
