How to Select Basil Varieties?

Most basil varieties and types grow well in hydroponics and containers. Nevertheless, which one will meet your demand on growing basil hydroponically?

Taking a look at the following characteristics of basil varieties will help you choose a suitable type of basil to grow.

  • Disease resistances
  • Preferred uses
  • Leaf types
  • Profile of flavor and aroma
  • Growth rate
  • Yield
  • Habit of the plant

You’ll better understand how to grow basil hydroponically, considering each system with unique requirements, and better predict the results that you can expect from each basil variety.

Once again, remember to consider the features mentioned above when choosing hydroponics basil types.

What hydroponics system works best for basil?

Plants grown in hydroponics will generally thrive, but specific setups and conditions (location, temperature, lighting, etc.) will produce greater results.

We suggest utilizing a hydroponic gardening system, making it possible to prune and harvest your plants every single week without much effort. It is best to prune the plants to ensure that they produce a yield.

Different areas, greenhouse sites, ecosystems, and agricultural practices will vary in their capacity to produce the same plant cultivars.

Growers should conduct on-site trials to see how well the crop performs under its normal operating conditions. The common medium used with growing basil in hydroponics is Rockwool blocks.

You can also use vermiculite, peat moss, perlite, and coco coir. Before using these mediums, you want to sterilize them.

Besides, you want to choose hydroponic systems based on operational preferences.

Ideal conditions for hydroponic basil

Unlike other crops, hydroponics basil will benefit from daily attention. The most critical factors are electroconductivity (EC), pH, nutrient composition, daily light integral (DLI), temperature, and light.

How To Grow Hydroponics Basil Effectively (Ph, Growth Rate)?

This herb generally prefers warm temperatures, a slightly acidic pH, a low level of EC, and reacts well to lots of light. However, these factors vary, depending on the season and the other variables.

We recommend these general conditions for basil to make it extra easy for novice gardeners.


If the plants cannot absorb enough water to replace that loss through transpiration, low humidity can cause green leaves to burn. Calcium deficiency can develop if the humidity level rises too high.

Sweet basil thrives in the humidity of 65%, while other plants only require 45 to 75%. The kind of culinary herb dies quickly when exposed to dry air.

The evaporating water will increase humidity in a hydroponic situation, but not always to sufficient levels. You can control and measure humidity by using hygrometers and psychrometers.

For the best results, remember to set a moderate amount of humidity.


Although basil does not require much water or pH, it will grow and produce in a pH range of 5.5 to 6.8, but the ideal basil pH is a pH of 6.5 to 6.8.


What are basil light requirements? Hydroponics basil requires a minimum of 14 hours of light per day, and the Daily Light Integral (DLI) must be at least 12 mol per square meter squared per day.

Basil is a plant that thrives in bright light. It does not require a lot of light and can be grown in a T5 fluorescent light fixture.

We would recommend an LED grow light if you plan on using your grow light for more than just growing leafy greens and herbs like basil. Your crops need 14 to 16 hours of sunlight per day to grow properly.

It can survive with 10 to 12 hours of daily sunlight exposure but won’t thrive in yield and quality.


This herb grows best in an ideal temperature range of 65 to 80 degrees Fahrenheit (18 to 21 degrees Celsius) when grown hydroponically.

A temperature controller can help you better control the basil temperature in your growing room.


The plants grown hydroponically have a higher potassium and calcium mix in their feeding halves.

As a result, choose a calcium and potassium ratio that is well maintained. It’s generally at a high level, with a nearly 1:1 ratio.

It’s important to understand that potassium and calcium are linked to the oil and flavor of the basil leaves and branches.

Additionally, nitrogen is a deciding factor in the yield of leaves. Hence, it’s critical to keep it nearly constant at all times.

Magnesium is another essential element of hydroponic basil nutrients. Because magnesium has a direct link to its composition, it’s best to keep this nutrient at a level of at least 50 ppm.

It aids in the production of essential oils that contribute to the herb’s aroma and flavor.

Plant spacing

The optimal basil plant spacing is between 9 to 12 inches. To maximize yields, you’ll want to encourage lateral growth.

To boost yields, promoting lateral growth is a must. Spacing about 5 to 6 inches apart between the plants is perfect for adequate airflow.

If your greenhouse environments usually are very humid, applying neem oil will protect the plant and stop fungal problems from spreading quickly.

How to prune and harvest basil?

The basil growth rate is about 28 days in hydroponic systems under optimal conditions. This kind of herb is a single-stemmed, upward-growing plant that has been bred. This growth tendency is called apical growth.

A bushier plant is better for most growers, and a well-pruned plant has a good shape, yields more, and can be transported more quickly, according to your method of growth.

Growers can boost the plant’s branch while maintaining the desired shape of the plant by pruning.

You want to lightly wrap the harvested basil and store it at the temperature range between 52 to 57 degrees Fahrenheit.

Hydroponic basil is simply a soil-free version, ensuring it has virtually no soil-crop problems and is the best thing about this herb.

How To Grow Hydroponics Basil Effectively (Ph, Growth Rate)?

It is a popular hydroponic choice because it is ideal for the aroma and taste when used freshly. So, let’s sum up the conditions that help this crop grow ideally:

  • EC: 1.6–2.2
  • pH range: 5.5–6.8
  • Temperature: 65–80 degrees Fahrenheit

You can not find these qualities in dried basil, so it’s not unusual to see greenhouses and restaurants grow their herbs in a hydroponic system.

They have a fantastic ability to grow the most delicious basil, and it is worthwhile to have in your home garden.

Final Thoughts

So you have gone through how to grow hydroponics basil. In short, before starting to grow, you want to choose suitable basil varieties, along with setting up ideal growing conditions for them.
