Growing Coriander Without Soil: A DIY Hydroponic Adventure!
Hey there, fellow plant enthusiasts! Ever dreamt of having fresh coriander (cilantro for my American friends!) right at your fingertips, without the mess of soil? Well, you’re in the right place! I’m going to walk you through a super fun and surprisingly easy DIY hydroponic setup specifically for growing coriander. Trust me, it’s a game-changer.
This project is perfect for anyone with limited space, a desire to experiment, or just a general dislike of getting their hands dirty (though, let’s be honest, a little dirt never hurt anyone!). We’ll be using a simple Kratky method, which is a passive hydroponic system – meaning no pumps or electricity needed after the initial setup. How cool is that?
What You’ll Need: The Supply List
Before we dive in, let’s gather our supplies. Don’t worry, most of these are readily available and won’t break the bank.
* A Container: This will be our reservoir. I recommend a dark-colored, opaque container (like a black bucket or a dark storage bin) to prevent algae growth. The size depends on how much coriander you want to grow. A 5-gallon bucket is a good starting point.
* Net Cups: These will hold our coriander seedlings. You can find these online or at most hydroponics stores. 2-inch net cups are a good size.
* Hydroponic Growing Medium: We need something to support the seedlings in the net cups. Coco coir, rockwool cubes, or even clay pebbles (LECA) work great. I personally prefer coco coir for coriander.
* Hydroponic Nutrients: This is crucial! Coriander needs specific nutrients to thrive. Look for a balanced hydroponic nutrient solution formulated for leafy greens. Follow the instructions on the bottle carefully.
* Coriander Seeds: Obviously! Choose a variety that you like.
* Rockwool Starter Plugs (Optional but Recommended): These are fantastic for starting seeds. They provide a sterile and consistent environment for germination.
* pH Testing Kit (Optional but Recommended): Maintaining the correct pH is important for nutrient absorption. A simple pH testing kit will help you keep things in check.
* Measuring Cups and Spoons: For accurately measuring water and nutrients.
* Drill with Hole Saw Attachment (Sized to fit your net cups): To create holes in the lid of your container.
* Lid for your Container: This will hold the net cups.
* Water: Tap water is usually fine, but let it sit out for 24 hours to allow chlorine to evaporate.
* Spray Bottle: For misting seedlings.
* Grow Light (Optional): If you don’t have a sunny spot, a grow light will be essential.
Phase 1: Seed Starting – Getting Those Little Guys Going
This is where the magic begins! We need to germinate our coriander seeds before we can move them to the hydroponic system.
1. Soaking the Seeds (Optional but Recommended): Some people find that soaking coriander seeds in water for 24 hours before planting helps with germination. I’ve had success both with and without soaking, so it’s up to you.
2. Preparing the Rockwool Plugs (If Using): If you’re using rockwool plugs, soak them in water for a few minutes until they’re fully saturated. Gently squeeze out any excess water.
3. Planting the Seeds: Place 2-3 coriander seeds in each rockwool plug (or directly into your chosen growing medium if you’re skipping the rockwool). Gently cover the seeds with a thin layer of the growing medium.
4. Creating a Humid Environment: Place the rockwool plugs (or your seed-filled growing medium) in a tray or container with a lid. This will help maintain humidity and encourage germination. You can also use a plastic bag to cover the tray.
5. Misting Regularly: Keep the growing medium moist by misting it with water 1-2 times a day.
6. Providing Light: Place the tray in a warm, bright location. If you don’t have a sunny spot, use a grow light.
7. Waiting for Germination: Coriander seeds typically germinate in 7-14 days. Be patient!
Phase 2: Preparing the Hydroponic System – Building Our Soil-Free Oasis
While the seeds are germinating, let’s get our hydroponic system ready.
1. Drilling the Holes: Take the lid of your container and use the hole saw attachment to drill holes that are slightly smaller than the diameter of your net cups. You want the net cups to fit snugly in the holes. Space the holes evenly across the lid, allowing enough room for the coriander plants to grow.
2. Cleaning the Container and Lid: Thoroughly clean the container and lid with soap and water to remove any dirt or debris. Rinse well.
3. Mixing the Nutrient Solution: Fill the container with water, leaving a few inches of space at the top. Add the hydroponic nutrient solution according to the instructions on the bottle. This is important: Don’t overdo it! Too much nutrient solution can harm your plants.
4. Checking the pH (Optional but Recommended): Use your pH testing kit to check the pH of the nutrient solution. Coriander prefers a pH between 6.0 and 6.5. If the pH is too high, add a pH-down solution. If it’s too low, add a pH-up solution. You can find these solutions at most hydroponics stores.
5. Placing the Lid on the Container: Carefully place the lid on the container.
Phase 3: Transplanting and Growing – Watching the Magic Happen
Once your coriander seedlings have developed a few true leaves (the leaves that look like miniature versions of adult coriander leaves), it’s time to transplant them to the hydroponic system.
1. Gently Removing the Seedlings: Carefully remove the seedlings from the rockwool plugs (or your chosen growing medium). If the roots are tangled, gently tease them apart.
2. Placing the Seedlings in the Net Cups: Place each seedling in a net cup, surrounding the roots with your chosen hydroponic growing medium (coco coir, rockwool, or clay pebbles). Make sure the roots are well-supported.
3. Inserting the Net Cups into the Lid: Insert the net cups into the holes in the lid of the container. The bottom of the net cups should be submerged in the nutrient solution.
4. Providing Light: Place the hydroponic system in a sunny location or under a grow light. Coriander needs at least 6 hours of light per day.
5. Monitoring the Water Level: Check the water level in the container regularly. As the plants grow, they will absorb water. Add more nutrient solution as needed, maintaining the correct concentration.
6. Maintaining the pH (Optional but Recommended): Check the pH of the nutrient solution every few days and adjust as needed.
7. Providing Air Circulation: Good air circulation is important to prevent fungal diseases. If you’re growing indoors, consider using a small fan to circulate the air.
8. Harvesting: You can start harvesting coriander leaves when the plants are about 4-6 inches tall. Simply snip off the leaves as needed. The more you harvest, the more the plants will produce!
Troubleshooting Tips: Keeping Your Coriander Happy
Even with the best setup, you might encounter a few challenges along the way. Here are some common problems and how to fix them:
* Yellowing Leaves: This could be a sign of nutrient deficiency. Make sure you’re using a balanced hydroponic nutrient solution and following the instructions on the bottle. It could also be a sign of overwatering, although that’s less likely in a Kratky system.
* Slow Growth: This could be due to insufficient light, incorrect pH, or nutrient deficiency. Make sure your plants are getting enough light, the pH is within the correct range, and you’re using a balanced nutrient solution.
* Algae Growth: Algae can grow in the nutrient solution if it’s exposed to light. Use a dark-colored, opaque container to prevent algae growth. You can also add a small amount of hydrogen peroxide to the nutrient solution to kill algae.
* Root Rot: This is a fungal disease that can cause the roots to rot. It’s usually caused by poor air circulation or overwatering. Make sure your plants have good air circulation and avoid overwatering. If you suspect root rot, remove the affected plants and replace the nutrient solution.
Extra Tips for Coriander Success: Going the Extra Mile
* Successive Planting: To ensure a continuous supply of coriander, start new seeds every few weeks.
* Bolting: Coriander is prone to bolting (going to seed) in hot weather. If you live in a hot

Frequently Asked Questions (FAQ)
What exactly is soil-free coriander growing, and why should I try it?
Soil-free coriander growing, often referred to as hydroponics, is a method of cultivating coriander plants without using traditional soil. Instead, the roots are suspended in water or an inert medium and provided with a nutrient-rich solution. You should try it because it offers several advantages: faster growth, higher yields, reduced risk of soilborne diseases, less water usage, and the convenience of growing herbs indoors, regardless of space constraints. It’s a fantastic way to have fresh coriander readily available, even if you have a “brown thumb” when it comes to traditional gardening.
What kind of nutrient solution do I need for growing coriander without soil?
You’ll need a hydroponic nutrient solution specifically formulated for leafy greens or herbs. These solutions contain the essential macronutrients (nitrogen, phosphorus, potassium) and micronutrients (iron, manganese, zinc, etc.) that coriander plants need to thrive. You can find these solutions at most garden centers or online retailers. Follow the instructions on the nutrient solution label carefully, as the concentration needs to be precise to avoid nutrient deficiencies or toxicities. Start with a diluted solution and gradually increase the concentration as the plants grow.
How often should I change the nutrient solution?
The frequency of changing the nutrient solution depends on several factors, including the size of your container, the number of plants, and the temperature. As a general rule, you should change the solution every 1-2 weeks. However, it’s important to monitor the solution regularly and change it more frequently if it becomes cloudy, discolored, or develops an unpleasant odor. Algae growth can also indicate that it’s time for a change. Regularly topping off the water level with fresh water is also important.
