Pepper Hydroponics: The Best System

The most effective hydroponic systems for growing peppers are deep water culture (DWC), ebb-and-flow, and wick systems.

Peppers grow best in deep water culture systems because they are the simplest to set up and maintain. In-depth details are provided in this DWC article.

In terms of space, power, and water requirements, each type of system has advantages and disadvantages.

For instance, you can fit a lot more plants in ebb-and-flow (explained here) and wick systems and only have to maintain one reservoir, but the plants won’t grow as big as they would in a DWC setup.

Starting Hydroponic Peppers: A Guide

Planting your seeds is the first step in starting hydroponic peppers.

This can be accomplished in a variety of ways, including in soil, rockwool or another inert growing medium, or in some sort of seed-starting system.

These rockwool cubes are very simple to use and come in a pack of 24 at a great price.

Keep your seeds in a warm, well-lit, and moist environment. Around 70°F is the ideal temperature for pepper seed germination.

Once two distinct sets of leaves have sprouted on the plants, they are ready to be transferred.

Put them right into the hydroponic system’s grow spaces, then sit back and watch it all happen.

The ideal distance between the lights and the top of the crops when growing indoors in a hydroponic system is between 6 and 8 inches.

According to the type, intensity, and settings, adjust the lights as necessary.

How Long Does Hydroponically Grown Pepper Take?

Depending on the species you are working with, a hydroponic pepper plant can be grown in about 60 to 80 days.

The best method for growing peppers a little bit more quickly than usual is to shorten the germination period.

Two full weeks can be removed from the total time frame by limiting the 7–21 day germination period to no longer than a week.

The seeds can be started in a small greenhouse, hothouse, or seed-starting system to achieve this.

Do Peppers Grown in Hydrogen Taste Good?

In comparison to peppers grown in soil, hydroponic peppers are known to be bigger, tastier, and better smelling.

They taste better than other peppers, so why wouldn’t that be the case?

The pepper plants are given the best lighting, water, nutrients, and other conditions when they are raised hydroponically (not just survive and produce an acceptable crop).

Can Peppers Be Grown Indoors in Hydroponics?

The fact that it can be done indoors adds to its beauty, as it does with most hydroponic crops.

When growing hydroponically indoors as opposed to outdoors, lights and ventilation are required.

Home gardeners frequently prefer indoor hydroponics to outdoor hydroponics for growing peppers because indoors, you have total control over the environment.

You are constantly up against the elements outside.

Whether or not you will want or need a grow tent is another thing to think about when growing peppers hydroponically.

Even more environmental control is possible with a grow tent than with indoor growing in a room.

pH of Hydroponic Peppers

In terms of pH levels, peppers are a relatively simple hydroponic crop.

Depending on the species, they can tolerate pH values as low as 5.5 or a little bit lower, but they prefer a range of 6.0 to 7.0.

It’s also crucial to remember that hydroponic peppers need an EC level of 2.0, which is somewhat high (or even higher in some cases).

The pH level may be exactly where it should be if your peppers have a low EC, but the plants won’t be able to absorb the critical nutrients.

The pH and EC levels of your hydroponic peppers should be monitored daily as a best practice. A good idea is to keep a notebook with the readings.

In our article, you can find a comprehensive guide for adjusting and maintaining these levels.

How Much Light Do Peppers Grown in Hydroponics Need?

When grown hydroponically, peppers need a full day of sunlight. Hydroponic peppers need anywhere from 12 to 18 hours of light per day indoors.

The variety of peppers and the type of lighting power determine how many hours there are in a day.

The lights should typically be positioned between 6 and 8 inches from the tops of the pepper plants.

Twelve inches might be more suitable for certain species and types of lighting.

In any case, keep in mind to raise the lights as the plants develop so that the distance is consistently ideal for encouraging new growth.

These are the same lights I used when I first started out.

Nutrient-rich hydroponic peppers

The following macro- and micronutrients are necessary for hydroponic pepper growth:

  • Ammonium (NH4) (NH4)
  • Boron (B) (B)
  • Calcium (Ca) (Ca)
  • Chloride (Cl) (Cl)
  • Copper (Cu) (Cu)
  • Iron (Fe) (Fe)
  • Magnesium (Mg) (Mg)
  • Manganese (Mn) (Mn)
  • Molybdenum (Mo) (Mo)
  • Nitrate (NO3) (NO3)
  • Potassium (K) (K)
  • Phosphate (PO4) (PO4)
  • Sulfates (SO4) (SO4)
  • Sodium (Na) (Na)
  • Zinc (Zn) (Zn)

Verify the ingredients with the above list before buying liquid plant nutrients to make sure they contain everything your peppers require.

Should You Wash Peppers Grown in Hydroponics?

Peppers grown in hydroponic systems must be washed off just like any other crop, and this requirement is unaffected by the method of growth.

Before being cooked, consumed, or stored, all plants should be thoroughly washed.

Both peppers grown in soil and those grown hydroponically lack harmful contaminants on their fruits.

If there is a contamination, you are likely the one who introduced it (foliage spray or pesticide, perhaps).

Bell Pepper Yield Per Plant in Hydroponics

Bell peppers grown hydroponically typically yield between 50 and 100 pounds.

The difference is astoundingly large when compared to soil-grown bell peppers, which are unable to produce more than 5 pounds.

How long do pepper plants grown in hydroponics live?

Depending on the species, pepper plants can live for up to three years or longer.

However, because pepper plants are so easily replaced with new seedlings, the average pepper plant lives for much shorter periods of time.

Common Issues with Hydroponic Peppers

The following are a few of the most significant issues you might run into when growing peppers hydroponically:


Aphids, spider mites, whiteflies, and fungus gnats are a few of the most frequent insects that might land on your hydroponic pepper plants.

Considered as a whole, spider mites are the worst.


Using preventive measures like organic pest control techniques or pesticide spraying is the most effective way to get rid of pests.

Lack of Lighting

For plants, the best light is always sunlight.

You can be sure that your lights are the problem if you are growing indoors and everything is set up and maintained properly, but your pepper plants never seem to thrive.


You must make the appropriate indoor grow light investments, such as LEDs or strong fluorescents, to grow peppers hydroponically.

Make sure to use lights that are powerful enough by doing some research based on the size and type of system you are running (or will be running).

failing to keep an eye on your plants

You’ll need to continue keeping an eye on things once your system is up and running and your pepper plants are flourishing.

In fact, you need to monitor more to ensure that things keep going smoothly when everything is going well.


The pH, EC, water temperature, and general health of your hydroponic system and plants should all be checked on a daily basis.

If you need a reminder, set an alarm on your phone. You can also use quality testing tools, such as this one that quickly and accurately measures pH, TDS, and EC.

Insufficient Maintenance of Your Hydroponic System

You must maintain your system properly in addition to monitoring it.


You must disassemble some components of your system every two to three weeks, clean them, and then reassemble them.

Additionally, fresh water and liquid nutrients must be added to the main reservoir’s water to replace the existing water. It’s also recommended to clean out grow spaces, pumps, and filters.

Although they are simpler to grow than many other crops, peppers are not perfect. In this article, you will learn about 26 common issues and how to fix them.

Guidelines for Hydroponic Pepper Growing

Here are some excellent suggestions for growing peppers hydroponically:

Put a plant there every 12 inches.

Depending on who you ask, different people will have different suggestions for hydroponic pepper spacing.

While some gardeners space them up to 24 inches apart, others spread them out between 6 and 8 inches.

We advise a 12-inch gap between hydroponic pepper plants. In this manner, they have enough space to spread out and grow enough branches to yield more fruit.

Set the lights on timers.

If you’re already using one, it might seem obvious, but if not, you should definitely think about the advantages of using a timer on your hydroponic pepper plant’s lighting system.

This smart plug is the way to go, so I switched to using it for my timer and haven’t looked back.

An unpredictable lighting schedule will undoubtedly stress a plant out, slow its growth, and possibly ruin your entire harvest.

Daily EC, pH, and PPM monitoring

One of the most important things you can do to guarantee a successful crop of hydroponic peppers is to regularly check the levels of your hydroponic reservoir.

You can determine precisely how many nutrients and other solvents are present in the water and available to the plants by using the pH and PPM readings.

PPM, or TDS readings, are completely explained here.

Due to the water’s electric conductivity, the EC level determines whether or not the pepper plants will be able to absorb enough nutrients through the water.

When growing peppers, make sure the EC level in your system is as close to 2.0 as possible.

Every 14 days, replace the water and nutrients.

Water readings for your hydroponic peppers must be closely monitored, and every exact two weeks, you must completely replace the water.

Some gardeners choose to wait an extra week, choosing instead to add some fresh water and nutrients to the reservoir’s top, but we advise biting the bullet and replacing it every 14 days as scheduled.

To ensure that your pepper plants continue to receive the best conditions for growth and success, remember to rebalance the pH and EC when you change the water.

A Final Word on Hydroponic Pepper Growing

Peppers grown hydroponically are a great crop for both novice and experienced home hydroponic gardeners.

Large yields, low maintenance requirements, and a high level of market demand are all characteristics of this crop.

All you need to get started are a few pepper seeds (or starter plants), your preferred hydroponic system, and a few other small supplies (as mentioned above).
