Growing strawberries using hydroponics is a smart and efficient way to enjoy sweet, juicy berries year-round—even without a traditional garden. This guide from Start a Garden walks you through every step of growing hydroponic strawberries, from system setup to harvest, along with common problems, solutions, and beginner FAQs.
What Is Hydroponic Strawberry Farming?
Hydroponics is the method of growing plants in a nutrient-rich water solution without soil. In strawberry hydroponics, plants are grown in systems that deliver water, oxygen, and nutrients directly to the roots. This enables faster growth, cleaner produce, and higher yields compared to traditional methods.
Best Hydroponic Systems for Strawberries
- Nutrient Film Technique (NFT) – A thin stream of nutrient solution flows over plant roots in a shallow channel. Best for lightweight crops like strawberries.
- Ebb and Flow – Periodically floods and drains a grow tray. Great for larger setups.
- Drip System – Nutrient solution is dripped slowly onto each plant. Offers precise control.
Recommendation: NFT is ideal for hydroponic strawberries because it supports small root systems and allows continuous nutrient flow.
Step-by-Step: How to Grow Hydroponic Strawberries
1. Choose Strawberry Varieties
Day-neutral or everbearing types like ‘Albion’, ‘Seascape’, or ‘San Andreas’ are best for hydroponics because they produce fruit continuously.
2. Prepare Your System
- Install trays or channels (for NFT or ebb and flow)
- Connect the reservoir and air pump
- Add a water pump and timer if needed
- Ensure proper lighting (LED grow lights for indoor setups)
3. Mix the Nutrient Solution
Use a balanced hydroponic nutrient mix with key elements like nitrogen (N), phosphorus (P), potassium (K), calcium, and magnesium. Maintain:
- pH: 5.5–6.5
- EC: 1.2–1.8
4. Transplant the Strawberry Seedlings
Use net pots filled with a growing medium like coconut coir, rockwool, or clay pellets. Gently insert the seedlings so roots reach the water flow.
5. Provide Light and Temperature
- Light: 12–14 hours daily with full-spectrum LED grow lights
- Temperature: 60–80°F (15–27°C)
- Humidity: 60–70%
6. Pollinate Flowers Manually
Since there are no insects indoors, use a soft brush or shake the plant gently to transfer pollen from flower to flower.
7. Monitor and Maintain the System
- Check water levels and nutrient strength every few days
- Clean the reservoir every 2–3 weeks
- Watch for leaf color changes or root discoloration
8. Harvesting
Strawberries are ready to harvest when they’re fully red and slightly soft to the touch. Pick them every 2–3 days during peak production.
Common Problems and How to Fix Them
Problem 1: Yellow Leaves
Cause: Nutrient deficiency or incorrect pH.
Solution: Adjust pH to 5.5–6.5 and use a complete nutrient solution.
Problem 2: Root Rot
Cause: Poor aeration or stagnant water.
Solution: Increase oxygen with an air stone and clean water weekly.
Problem 3: Small or Misshapen Fruits
Cause: Inadequate pollination.
Solution: Use a soft brush to pollinate manually every few days.
Problem 4: Algae Buildup
Cause: Light exposure to water.
Solution: Cover all water containers and use opaque materials.
Problem 5: Weak Growth or No Fruit
Cause: Insufficient light or nutrients.
Solution: Ensure 12–14 hours of light and adjust nutrient levels accordingly.
FAQs About Hydroponic Strawberries
Q1: Can I grow strawberries year-round in hydroponics?
A: Yes, hydroponic systems allow you to grow strawberries indoors regardless of the season.
Q2: How long do strawberries take to fruit in hydroponics?
A: Typically 6–8 weeks from transplanting, depending on the variety and conditions.
Q3: Are hydroponic strawberries organic?
A: They can be, but certification depends on local regulations. Always use organic nutrients if certification is a goal.
Q4: Do strawberries taste different when grown hydroponically?
A: Hydroponic strawberries often taste sweeter and juicier because you control nutrients and conditions.
Q5: How many strawberries can I grow in a small hydroponic setup?
A: A compact NFT system can grow 10–20 plants in just a few square feet.
Final Thoughts
Hydroponic strawberries are a fun, sustainable, and productive way to grow delicious fruit at home. With the right setup, regular care, and attention to details like nutrients and pollination, even beginners can enjoy fresh strawberries straight from their indoor garden.
