“In order to manage this in a hydroponic system, you should plan to use a pair of garden shears to prune the plant and keep it at about eight inches tall. That will keep the energy flowing into the peppers so that they taste amazing. Bell peppers will take about 90 days after seedlings start to show. During those 90 days, bell peppers require a lot of light, and you can expect to give them a minimum of 18 hours a day. However, bell peppers can actually handle 24 hours of light, and so it is often more effective just to give them a dedicated light that you never shut off. While bell peppers require a pH level between 6.0 and 6.5, making them similar to lettuce and spinach, they should be grown in their own containers. They’ll need more nutrient solution to drink, and so grow bell peppers at a ratio of one plant to three gallons of water.”
