If you have at least one window that gets full sun, you can grow herbs in pots from seed. Grow lights can also be used to supplement lesser amounts of sunlight, but they should not be the sole source of light for sun-loving herb plants. Nearly all herbs require full sun, with the exceptions of sweet cicely, angelica and sweet woodruff. Only water when soil is dry, and apply fish emulsion or other balanced liquid fertilizer to established potted herb plants.
Fill pots with potting soil. Sow herb seeds according to package instructions regarding depth.
Mist the soil with a mister bottle filled with water to avoid disturbing the soil or seeds.
Cover each pot with plastic wrap to create a greenhouse effect. Place pots in a window that gets filtered sun, such as through blinds or curtains.
Mist daily until seedlings emerge. Remove and discard the plastic wrap once seedlings have sprouted. Place pots in a window that gets full sun. Supplement with grow lamps if your windows provide inadequate light.
Water less frequently once seedlings have emerged. Water only when the soil is dry to the touch, and water so that it runs out the drainage holes at the bottom of the pot.
Apply fish emulsion or another balanced liquid fertilizer once a month according to package instructions.
Use insecticidal soap if you notice any pest infestation problems. Spray the plant directly, or hold it upside down and dunk it in a bucket of insecticidal soap to coat the leaves.
Repot your herbs if necessary. As herbs grow, you may notice that they have become root-bound, such as having roots poking out the drainage holes. In this case, repotting is a necessity. Choose a pot one size larger, use a little potting soil and gently loosen the root-bound herb from its old pot to move it to the larger one.
