What You Should Know About Hydroponically Producing Cilantro

Cilantro is a simple crop to cultivate in a hydroponic system. However, like growing other hydroponic vegetables, you would need a couple of fundamentals as you proceed.

Before getting started, you’ll need the following:

  • Your pick of hydroponic setup
  • Seeds of coriander
  • A reservoir of healthy, pure water
  • Supplements or fluid fertilizer
  • Medium for germination
  • Seedling-growing tray
  • Lighting (if growing indoors)
  • Temperature and humidity regulation (if growing indoors)

Anticipate the procedure to span one and a half or two months from seed to yield.

Per the instructions provided, you ought to be eating your fresh hydroponic cilantro within a matter of weeks!

  • For 2 hours, immerse 1-inch broad Rockwool seeding cubes inside a pan of water. Remove any surplus water from the cubes and place 2 or 3 seeds inside the middle of each. Put the tray inside a warm space with ambient lighting and cover using a transparent plastic sack or layer of plastic covering.
  • Keep an eye on their seed sprouting and sprinkle the cubes 3 to 4 times every week using water to maintain them wet. When sprouts develop, discard the cover and place the tray in a bright location. To keep the cubes from drying completely, spritz them once every day.
  • When your cilantro seedlings are 2 inches in height, set up your hydroponics equipment. Power on your system then pump it with water to ensure that things are functioning efficiently.
  • Obey the product directions for the water quantity inside the system when adding fertilizers to the water. Per each gallon of water within the system, use around 3 tablespoons of nutrient solution. To preserve a sufficient quantity of nutrients for crop development, add fertilizer to the water any time you renew it or add extra.
  • Put the 1-inch cubes inside 3- or 4-inch cubes which match the hydroponics setup you’re utilizing to grow the cilantro sprouts. Do not extract the sprouts from the tiny cubes, the layout makes it possible for you to embed them into bigger cubes to avert root injury.
  • Overlay an interior hydroponics setup with a halide grow-light arrangement. Put the bulbs 6 inches above the crops and leave them running for 12 hours every day. Once the cilantro develops higher, adjust the lights to encourage upwards development and keep the plant from burning.
  • When your hydroponics cilantro crop starts to spread out and grows higher beyond 8 inches, cut the foliage off. Trim bloom development to keep the plant from becoming bitter-tasting.

Cilantro Temperatures In Hydroponics

Cilantro is a tough plant to cultivate because it bolts fast, particularly in hot conditions. As a result, this plant thrives in milder conditions (40-75 ° Fahrenheit) plus reduced salt concentrations.

New cilantro growth prefers chilly temperatures, especially temperatures mostly in the 60s leading to better germination chances than those around the 70s and 80s.

If bolting is induced, clip the bolts then change the environmental settings. The taste of the vegetables becomes more sour and unpalatable when the crop has bolted.

Slow bolting cultivars can be purchased to prevent yield losses.

Hydroponic Cilantro EC, TDS, and pH Values

The EC content, overall, influences how efficiently the cilantro roots can absorb minerals and moisture. Cilantro has an optimal EC level of 1.5.

The TDS measurement must be around 800 and 1,000, with adjustments as appropriate. Its pH value should be in the range of 6.0 to 6.8.

Cilantro Hydroponics Spacing

The recommended spread for hydroponic cilantro would be nine to twelve inches.

Crops should be spaced according to these specifications to enable properly grown cilantro once it begins to flourish and require more area.

Hydroponic Cilantro Lighting Needs

Cilantro grows well in low-light environments. Since you simply use cilantro whenever it’s growing and producing leaves, you can grow it from seed to yield with the exact lighting.

While fluorescent lighting system has been the most practical for hydroponic cilantro cultivation, LED or HID illumination may also be employed.

For healthy development, the hydroponic cilantro must be subjected to around 12 to 14 hours of exposure every day.

Hydroponically Grown Cilantro Nutrients

Hydroponic Cilantro Nutrients
  • You should consider the nutritional requirements of hydroponic coriander when growing it. To prepare the formula, you can use both inorganic and organic nutrient solutions.
  • Inorganic nutrients break down swiftly in water but also require only a minimal quantity to satisfy their needs. Excessive nutrients, on the other hand, might induce poisoning inside the solution.
  • The organic solution, on the other contrary, is just a slow-release nutrient that may give all of the minerals in the water. One disadvantage is that when the system is not properly managed, the water purity may suffer.
  • Notwithstanding, you could also end up making the solution even more productive by combining organic as well as inorganic NPK nutrients. The ideal NPK for cilantro/coriander would either be 19-19-19 or 20-20-20. 1 tablespoon NPK nutrients in 1-liter water
  • Urea can be dissolved using water and then sprayed on leaves to help them develop faster. Because this plant is thick and bushy, be sure to apply sufficient nitrogen plus phosphorus.
  • To make a nutrition solution, you could also utilize hydroponic nutrients. These nutrients promptly supply critical nutrients.

Cilantro Harvesting In Hydroponics

  • Your cilantro crop may be plucked properly after it reaches approximately 6 inches in height.
  • To do just that, clip the topmost third of your crop off at the stalk. Clipping using sharp cutters will result in a neat cut that will not harm your plant’s root structure.
  • The above harvesting procedure serves two purposes. For starters, it delivers a crop of healthy cilantro greens.
  • Furthermore, this prunes your cilantro crop, promoting lateral proliferation and plant maturation.
  • Additionally, tiny quantities of cilantro can be harvested for instant application in cooking. It can be achieved by chopping off the upper portion of a couple of stems or clipping off the foliage.
  • This technique of harvesting yields very fresh, flavorful cilantro that is ideal for cooking.

Cilantro: How To Keep It Fresh

For long-term preservation, cilantro could be cooled, frozen, or even dried.


  • Fill a big glass halfway using water to keep cilantro refrigerated. Insert the clipped end of the stalks inside the glass to retain moisture.
  • Cover the cilantro as well as glass with a thick plastic snack bag.
  • To preserve cilantro healthy for 2-4 weeks, place this contraption inside your refrigerator then replenish the water each handful of days.


  • There are a few alternative approaches for freezing cilantro.

  • Cilantro may be frozen lasting up to two months using either approach.


  • Preheat your oven to 300 degrees Fahrenheit (180 degrees Celsius). Strip the leaves off the branch and set them on newsprint or non-stick sheet over a baking pan.
  • Put the leaves in a straight line on the baking pan. Dry for about 30 minutes at 350°F.
  • Remove the baking tray from the oven then set it aside to cool. Place the cilantro greens inside a sealed bag and crumble them.
  • Keep the dried cilantro leaves in the same place you preserve your flavorings.
  • Although dried cilantro lacks the zestiness of new cilantro, it is still a good approach to storing the herb for future usage.

Cilantro Hydroponic System: Which Is The Best?

Hydroponic methods for cultivating incredibly good cilantro include ebb and flow, DWC, NFT, drip, plus aeroponics.

Aeroponics as well as ebb and flow, on the other hand, are perhaps the most preferred hydroponic cultivating techniques for cilantro since they provide the crops more area than typical hydroponic techniques and installations.

If the given depth of your hydroponic nutrient formula is a minimum of 5 inches, you could also utilize float, pond, raft, or raceway formulation growth setups.

Maintaining conditions of at minimum 68°F / 20°C plus providing the plants with mild light conditions for newly sprouted seedlings, progressing to strong light conditions as the plants grow, are required.

The quantity of unstable chemicals and important oils within those herbs is affected by temperature, lighting, and the intensity of a nutritional solution.

Cilantro Cultivars That Grow Well In Hydroponics
