Introduction: Hello gardeners, today we are back with a great information of growing hydroponic peppers. Peppers can be grown using hydroponics at any time of the year. It has been proven that growing peppers hydroponically will not only result in an increased yield when properly done but commonly a better quality and larger fruit size as well. In hydroponics, the pepper plants theoretically receive a steady food source from the nutrient solution, and they incur have fewer attacks from insects and soil-borne pathogens.

A step by step guide to growing hydroponic peppers

You can produce more pepper plants with less space precisely because hydroponics systems can be modified to fit the available space. You can use hydroponics to grow peppers at any time of the year. It is possible to increase pepper size and production with this hydroponic type of indoor growing system. The plants get a constant food source from the nutrient-rich water, and they have few problems with pests and diseases that are often found in soil-grown plants.

Types of hydroponic systems those are ideal for growing peppers

Several styles of hydroponic systems are obtainable. Best for beginners are the deep-water system, Wick systems or ebb-and-flow types, which are ideal for growing green peppers.

Deepwater culture – Deepwater Culture (DWC) is also known as the reservoir method, is by far the easiest process for growing plants with hydroponics. In a Deepwater Culture hydroponic system, the plant roots are suspended in a nutrient solution. An aquarium air pump oxygenates the nutrient solution, and this keeps the roots of the plants from drowning. Remember to prevent light from penetrating your culture system, as this can cause algae to grow. This will wreak havoc on the system. The primary advantage of using a Deepwater Culture system is that there are no drip or spray emitters to clog. This makes DWC is a good choice for organic hydroponics, as hydroponics systems that use organic nutrients are more prone to clogs.

Wick systems – Wick systems are the simplest system mechanically and easiest to set up because there are no moving parts. The system consists of a reservoir filled with water and nutrients; above it, there is a container filled with a growing medium. The two containers are connected by a wick, which draws the nutrient-filled water up into the growing medium where it is absorbed by the roots of plants. This system is great for learning the basics, but it could not work well with large plants or with water-hungry plants like lettuce because the wick cannot supply water fast enough.

Ebb and flow systems – Ebb and flow systems are slightly complex in design, but they are extremely versatile. This system works mainly by flooding the growing medium with a water-nutrient solution and then draining it back into the reservoir. To do this, the system wants a submersible pump with a timer. One of the greatest benefits of ebb and flow is that you can use the timer to customize your plants’ watering schedule based on their size, number, ambient temperature, humidity, etc. You also have the option of potting plants individually for simple customization or filling the entire tray with growing medium and planting directly in the tray.

Space required for Hydroponic peppers

Hydroponics is the process of growing several plants without using soil. In the traditional sense of growing plants, the soil is one major way that plants get the nutrients they want to grow, along with the sun and water. With a hydroponic system, alternatives to those nutrients are directly fed to plants instead of being absorbed by the plants through soil. This way, the use of soil can be erased.

If you are planting bell pepper plants hydroponically, they need to be 18 to 24 inches away from each other. If you’re aiming for smaller chili pepper plants, then the plant spacing requirement is half. We’ve even seen pepper plants that are quite close to each other, but to ensure that the plants are getting enough light, a massive LED grows light is directed toward the plant leaves.

A simple, homemade tank hydroponics system holds the water, or growing solution, the growing medium, and plants, such as pepper plants. A plastic storage tote supplies a watertight container for the reservoir. Pond baskets, which are mesh pots that allow water to pass through, work well for holding the growing medium and the pepper plants. Hook up a hydroponics pump or a fountain pump to the reservoir with plastic tubing thus the water moves and doesn’t become stagnant. The hydroponic pump sits in a bucket of water outside the reservoir. Freshwater and the nutrient solution want to be added to the bucket and then pumped into the reservoir.

Planting medium for hydroponic peppers

Rock wool gives a sterile growing medium for peppers in a hydroponics system. It is made from spun basalt rock that’s turned into a fibrous material this is similar to fiberglass. You can germinate pepper seeds in rock wool and produce the resulting plants to maturity in the same medium. Fill the pond baskets with moistened rock wool, and then cut slits in the rock wool for planting each pepper seed.

Light for hydroponic peppers

Pepper plants, in general, require a lot of sunlight to thrive, so to be on the safe side, allow your plants to be exposed to 14 to 18 hours of light per day, with the remaining hours (eight to ten hours) for the nighttime cycle.

Nighttime is just as important as the daylight cycle as plants undergo vital processes that take place in the absence of light.

Optimal pH for peppers growing hydroponically

Assuming you are growing a variety of plants in addition to peppers you must be using a general nutrient formulation. Any nutrient suitable for Tomatoes or eggplants is also suitable for pepper plants.

The optimal pH level for peppers growing hydroponically is between 5.5 to 7.0. A low pH level can be corrected by adding sodium hydroxide or potassium hydroxide to the water. Small amounts of one or the other must be used. Never touch hydroxides with wet hands and handle them as little as possible and when you do, use sturdy water-resistant gloves. If possible, test any pH level adjustments on a single plant before you continue to make adjustments to your entire nutrient solution.

Germination stage in growing hydroponic peppers

The germination stage of pepper plants will likely take 7 to 14 days, fourteen being the upper limit. It takes an average of 50 to 80 days for pepper plants to be fully mature and ready for harvesting. Before this period, you will see a lot of flowering and vegetative growth, with pods growing bigger and redder with each passing day.

Simply maintain the formula you have been using for your pepper plants and wait for the right time to pick the pods from the stems. If your first batch of pepper plants does well, you can just keep the system or begin cloning from your best-performing plants.

  • Fill the hydroponics unit with water, and let it run for 2 or 3 days before planting the green peppers. Then add hydroponics nutrients to the water, using the package instructions for the volume of water in the system.
  • Remove the green pepper seedlings from their growing pot. Dip the root ball in a room-temperature bucket of water to gently loosen the soil around the plant roots. Remove as much soil as possible without damaging the roots and you can leave a small amount of soil on the roots when planting into the hydroponics system. Plant each soilless green pepper plant into a netted pot that containing a soilless hydroponics medium.
  • Set the pepper plants slightly deeper than they were growing in the original container. Plant one pepper in each netted pot, and space the pots 9 inches apart in the hydroponics system.
  • Set up indoor grow lights over top of the hydroponics so that the bulb is 6 to 8 inches above the top of the pepper plants. Place a timer on the lights so that they stay on for 10 to 12 hours each day. Raise the lights as the pepper plants produce taller to prevent burning the foliage. Monitor the water level in the hydroponics.
  • Add water as wanted to keep enough water in the system for proper growth. Add nutrients to the hydroponic system each time you refresh the water or add more to the reservoir, to provide proper nutrition for growth. Use the package instructions for the hydroponics nutrients based on the quantity of water you are adding.
  • Prune the pepper plants by pinching off 2 or 3 stem buds when the plants are about 6 to 8 inches tall to limit branch growth and force the plant energy toward pepper production.
  • Remove one or two buds from each pepper branch as they appear, which will increase the size of peppers formed from the remaining buds.
  • Shake the pepper plants 2 or 3 times a week when the buds open, to help with pollination. Place a small household fan near the hydroponics system and set it to low, to assist with pollination.

The best thing about using a hydroponics system is even if crops become hungry for more nutrients down the line, you can simply adjust the nutrient levels of your hydroponics setup to suit the requirements of your plants. Here are tips for planting hydroponic peppers.

  • Healthy pepper plants can be germinated from viable seeds. You can use cuttings and transplant them to hydroponics setup, but you will have to grow a viable root system first, which means you will still be using start plugs to accomplish this.
  • Starter plugs are necessary for most hydroponics projects so it is a good idea to have a steady supply of reliable starter plugs at home so you will always be ready to germinate seeds.
  • During the germination stage, the grow tray would want to be kept at around 26°C, so we highly recommend getting a heating mater. Otherwise, an additional grow light might help give the extra boost of heat to ensure that your pepper plants will sprout viable seedlings, and on time. The germination stage is so critical because if you obtain robust seedlings, you will likely get robust mature plants later on.
  • Your hydroponics setup should provide support to the pepper plants once they mature, so they do not tip over once they are heavy with foliage and pods.
  • Assemble the hydroponics unit in an indoor location with a daytime temperature of 73 to 78°F and an evening temperature of about 65°F.

Growing bell peppers in hydroponics

Bell pepper plants are a slightly more advanced hydroponic plant. Don’t let them grow to their full height, instead, prune and pinch plants at 8 inches to spur pepper growth.  A deep water culture system or ebb and flow systems are best for peppers.

Grow time of bell peppers will be about 90 days. The best pH level of these peppers is 5.5 to 7.0. Plan to provide up to 18 hours of light for these pepper plants each day, and raise light rack as the plants grow, keeping plants about 6 inches from the lights. Different bell pepper varieties suitable for the hydroponic system will be Ace, California Wonder, Vidi, and Yolo Wonder.

  • One of the best things about hydroponics is that less land is required to grow plants, compared to traditional farming methods.
  • Growing plants with hydroponics come with many advantages, the biggest of which is a greatly increased rate of growth in your plants. With the proper setup, plants will mature up to 25% faster and produce up to 30% more than the same plants grown in soil.
  • Plants grow faster and experts suggest that plants grow at least 20 percent faster in hydroponic systems than they do in soil.
  • Plant yields are 20 to 25 percent bigger with hydroponic systems compared to growing in soil.
  • No soil is required, which can be a distinct benefit in areas where existing garden soil is poor or for apartment dwellers that don’t have access to garden plots.
  • Your plants will produce bigger and faster because they will not have to work as hard to obtain nutrients.
  • A hydroponic system will use less water than soil-based plants because the system is enclosed, which results in less evaporation. Believe it or not, the hydroponic system is better for the environment because it reduces waste and pollution from soil runoff.
