Hydroponics is defined as growing plants in nutrient-rich water instead of soil. Growing pepper plants in an indoor hydroponics system will provide fresh produce through out the year, even during the winter. The plants will grow quickly, produce large vegetables and have reduced problems with disease and insects. Hydroponics systems are available at garden supply stores or a simple system can be constructed with household products. Deep-water or ebb-and-flow hydroponics systems are popular and easy-to-use types for beginners.
Purchase pepper plant seedlings or start your own from seed. Seedlings can be grown in soil to start and then transplanted into a hydroponics environment.
Prepare the hydroponics system so the peppers can be spaced at 3 square feet per plant. This allows room for the branching foliage.
Rinse the soil off the seedling roots and plant the peppers into hydroponics-netted pots filled with hydroponics medium or rock wool blocks.
Provide at least eight hours of direct light each day. Peppers will grow under natural or artificial light. If the peppers are grown outdoors, place a shade screen over the plants to control the amount of light and temperature around the plants.
Place the hydroponics system in a location that offers warm temperatures of 73 to 79 degrees Fahrenheit during the day and 65 to 66 degrees at night.
Train the pepper plants four weeks after planting. Select the strongest stems of each plant and attach them to support stakes. Adjust the plant attachment every two weeks as the plant grows.
Thin each pepper plant early in the growing season by pinching off the young buds. This will increase the amount of peppers produced. Prune the side shoots of each plant back to two leaves on the branch throughout the growing season.
Hand-pollinate the pepper plants by lightly shaking the plants every other day as soon as the blossoms appear.
