To grow hydroponic strawberries successfully, choose a day-neutral variety like Albion or San Andreas, set up a nutrient film (NFT) or vertical hydroponic system, maintain a pH between 5.8 and 6.2, provide 10–14 hours of daily light, and ensure pollination and pest control. Regular monitoring of nutrients and temperature keeps the plants healthy and ensures sweet, high-yielding fruits.
Step 1: Select the Right Strawberry Variety
Day-neutral and ever-bearing varieties such as ‘Albion’, ‘Evie2’, and ‘San Andreas’ thrive in hydroponic setups. These cultivars can produce fruit continuously under controlled indoor conditions.
Step 2: Choose Your Hydroponic System
Several systems work well for strawberries:
- NFT (Nutrient Film Technique): A thin, continuous flow of nutrient solution passes over roots.
- DWC (Deep Water Culture): Plants float in the nutrient solution, allowing root immersion.
- Vertical Towers: Great for small spaces — strawberries grow in stacked layers, maximising space and airflow.
Tip: For beginners, NFT or vertical systems are easiest to maintain and scale.
Step 3: Prepare the Seedlings
Start from runners or purchase clean seedlings.
- Remove all soil from the roots carefully.
- Rinse roots in lukewarm water.
- Use Perlite or a coco-perlite mix as the growing medium for excellent aeration.

Step 4: Mix the Right Nutrient Solution
Hydroponic strawberries need a balanced solution rich in nitrogen, phosphorus, potassium, calcium and magnesium.
- Maintain pH between 5.8–6.2.
- Keep EC (electrical conductivity) around 1.4–2.0 mS/cm for optimal uptake.
- Monitor weekly to prevent nutrient lockout.

Step 5: Provide Optimal Light
Strawberries need 10–14 hours of light per day.
- Use full-spectrum LED grow lights.
- Ensure even distribution across all plants.
- Keep lights about 12–18 inches above the canopy.
Step 6: Manage Temperature and Humidity
Maintain:
- Temperature: 60–75°F (15–24°C)
- Humidity: 60–75%
Too much humidity encourages mold and mildew. Use fans or dehumidifiers for airflow.
Step 7: Ensure Pollination
In indoor setups, hand-pollinate by gently shaking plants or using a soft brush to transfer pollen. For larger setups, introduce bumblebees or fans for natural pollination.
Step 8: Prevent Pests and Diseases
Watch for these common issues:
| Pest/Disease | Symptoms | Solution |
|---|---|---|
| Spider mites | Yellow spots, webbing | Neem oil or predatory mites |
| Aphids | Curling leaves | Ladybugs or insecticidal soap |
| Powdery mildew | White film on leaves | Increase airflow, use fungicide |
| Gray mold (Botrytis) | Soft, gray fruit | Improve spacing and airflow |
Preventive tip: Sterilise tools and clean reservoirs regularly.
Step 9: Harvesting
- Pick berries once they are deep red and fully ripe.
- Twist gently or cut with scissors.
- Expect harvests about 4–6 weeks after flowering.
Step 10: Maintain the System
Regular maintenance keeps the system productive:
- Check pH and nutrient levels weekly.
- Clean and disinfect equipment between cycles.
- Inspect plants for signs of stress or pest activity.
Step 11: Post-Harvest Storage
Fresh hydroponic strawberries last several days in cool, dry storage. For longer keeping, freeze or make preserves.
Final Thoughts
Growing hydroponic strawberries can be an incredibly rewarding experience. Not only does it allow for year-round cultivation in controlled environments, but the produce often tastes sweeter and more flavorful due to the precise nutrient delivery. With careful attention to detail and a passion for gardening, even a beginner can enjoy the fruits of their labor in no time. Whether you’re aiming to produce a small batch for personal consumption or scale up for commercial purposes, the hydroponic method is a sustainable and efficient way to enjoy fresh strawberries.
FAQ: Growing Hydroponic Strawberries
How long do hydroponic strawberries take to grow?
Hydroponic strawberries typically take 90 to 120 days from planting to the first harvest. Once flowering begins, fruits are usually ready within 4–6 weeks. Day-neutral varieties may produce berries continuously under stable indoor conditions.
What is the best pH level for hydroponic strawberries?
Maintain a pH range of 5.8 to 6.2 for optimal nutrient absorption. pH levels outside this range can lead to nutrient lockout, reducing plant health and yield.
Which hydroponic system works best for strawberries?
The Nutrient Film Technique (NFT) and vertical tower systems are most effective. These setups ensure consistent oxygen and nutrient delivery while maximising space — ideal for home or commercial growers.
How often should I change the nutrient solution?
Change the nutrient solution every two to three weeks, depending on plant size and water quality. Always clean reservoirs before refilling to prevent algae and bacteria buildup.
Do hydroponic strawberries need pollination?
Yes. Strawberries require pollination even in indoor systems. You can hand-pollinate using a soft brush or introduce airflow or bumblebees for natural pollination in larger operations.
Can I grow hydroponic strawberries indoors year-round?
Absolutely. With controlled light (10–14 hours daily), temperature (60–75°F / 15–24°C), and humidity (60–75%), hydroponic strawberries can thrive and produce fruit year-round.
Are hydroponic strawberries organic?
Hydroponic strawberries can be grown with organic-certified nutrient solutions, but whether they qualify as “organic” depends on regional certification rules. Check with your local agricultural authority for compliance requirements.
What are the common pests in hydroponic strawberry systems?
The most common pests are aphids, spider mites, and occasionally slugs. These can be managed using biological control agents (like ladybugs), neem oil, or insecticidal soap.
How do I increase the sweetness of hydroponic strawberries?
Maintain consistent light intensity, avoid overwatering, and keep EC between 1.4–2.0 mS/cm. Slightly lower nitrogen and higher potassium near fruiting also enhance sugar development.
What are the benefits of growing strawberries hydroponically?
Hydroponic systems offer faster growth, higher yields, fewer soil-borne diseases, and year-round production. They also use up to 90% less water compared to traditional soil cultivation.
