Step by Step Guide to How to grow Cilantro in Water
Method 1. Hydrophonic Cilantro
Hydroponics is a method of planting in a water-based, mineral-rich nutrient solution instead of soil. It is a very effective method that minimizes water wastage and water usage in farming. Besides, hydroponically grown greens are equally nutritious as those produced in the soil.
1. Choose your seeds
There are seven different varieties of Cilantro namely Slo Bolt, Caribe, California Long-Standing, Delfino, Leisure, Lemon, Moroccan, Jantar, Santos, Terra, and Costa Rica. Varieties like long-standing, Calypso Santo, Marino are slow bolting and ideal to grow hydroponically for cilantro leaves while for coriander seeds, all varieties of cilantro are considered good.
The seeds of cilantro are small and round. Each seed has two seeds within the follicle that germinates. So when you plant one seed you are actually planting two seeds. It’s best to soak hard seeds overnight before using them.
2. Soak your medium
Grow seeds in a Hydroponic grow cube, or a 1-inch wide net pot to avoid interrupting the seedlings and replanting them. Soak a Hydroponic grow cube in a tray filled with water. Squeeze out excess water so it remains damped. Put 2-3 seeds into the hole of each Hydroponic grow cube. Spread a thin plastic sheet or wrap to cover its top and then position it near a warm area with indirect sunlight to provide it a greenhouse effect.
3. Keep the medium moist
Spray the medium with water 2-3 times in a week to keep it moist and avoid it from drying. Focus on the germination of seeds. Lift the plastic cover once you see germination has begun. Move it to a sunshiny area to avoid legginess and poorly produced plants.
4. Set up the Hydroponic system
Once the cilantro plants grow 5cm in height, place them in a hydroponic system. The hydroponic system is a hydroculture medium that allows precise control over environmental requirements in the indoor planting. Before placing the cilantro plants, check whether the hydroponic system is operating correctly. Use a low concentration nutrient and provide the light on for a least of 12 hours. Start the wind and allow it to circulate gently through the crop.
5. Add nutrients
Add water-soluble or liquid fertilizer to the water according to the instructions given on the fertilizer. Repeat this step every time you restore the system. Assure the system does not dry out and also examine for bacterial leaf spots. Make sure your plants do not starve out.
6. Trim the cilantro
When the crop is about 20 cm in height then start harvesting the outer leaves. After 20 days of the plantation after planting of the first crop, you can start a second batch to continue the supply of Cilantro. Remove the bud to prevent the plant from turning bitter in taste. You should start harvesting the main cilantro leaves after 35 to 40 days. Once harvested use them as early as possible.

Method 2. In a Mesh Basket
- Take cilantro seeds and give them pressure treatment so the seeds will split half into two which will help them germinate properly. Even if you are growing them in the soil, you must use pressure treatment for seeds. Remember you just have to split the seeds and not crush them. Now Seeds are ready.
- Next, you will need a patila (pot or vessel) and fill it completely with water. Note that the vessel should not be transparent. Place a 1- inch wide Mesh basket over it. Spread few seeds over the mesh basket. Do not spread all the seeds at a time.
- Spread them, in an interval of 3 to 5 days to harvest cilantro in different lots. Note that seeds should remain in contact with water in the vessel. If needed pour some water from above without disturbing the seeds.
- Seeds should never get dry so make sure you sprinkle water regularly to keep them, moist. You can also place a moist cloth or a tissue paper over the top of the seeds to keep them damp. Now, place this set up in a sunny area but avoid extreme sunlight. Seeds will germinate in 10 to 12 days.
- After some days you will see roots growing downwards. Use a mineral-based liquid or solid water-soluble hydroponic fertilizer to add in water. Change water every 15 days and add 1/4 teaspoon of water-soluble fertilizer in the water.
- You should obtain the first harvesting of cilantro in 40 to 50 days then every 6 to7 days. Growing cilantro in water is difficult in case of TDS in the water you use is more than 400 and also the high concentration of salt in the water. In that case, you can use RO water.
