What fertilizer to use for hydroponic lettuce?
Lettuce Fertilizer 8-15-36 Plus Micro Nutrients
The fertilizer is blended to offer a balanced ratio of nitrogen, potassium, and phosphorous as well as key micronutrients like boron, copper, iron, manganese and more. Because it’s water soluble, our lettuce fertilizer is also ideal for hydroponic lettuce growth.
What is the best NPK for hydroponic lettuce?
Higher nitrogen levels speed up a plant’s growth rate. This 7-9-5 ratio is a great all around vegetative nutrient for growing hydroponic vegetables.
What is the best fertilizer for lettuce?
Feed lettuce plants every two weeks with a balanced water soluble or granular fertilizer, such as a 10-10-10 or a 5-5-5, diluted to half strength. Look for a fertilizer in which the three numbers separated by hyphens are equal or almost equal.
What is the best pH for hydroponic lettuce?
5.5 to 6.0
Hydroponic lettuce should be grown with a narrower pH range of 5.5 to 6.0, with an optimal target value of 5.8. During germination, hydroponic lettuce should be fertilized with 100 to 150 ppm N, maintaining a solution EC around 1.2 mS/cm. During production, maintain a solution EC of 1.5 mS/cm.
What is the best organic fertilizer for lettuce?
Fish emulsion is an ideal organic fertilizer for lettuces. Apply the fish emulsion at half of the recommended dosage every two weeks. It is best to apply the diluted fish emulsion directly to the soil. You can use it as a foliar feed as well, but be sure to wash your lettuce really, really well before eating it.
What makes hydroponic lettuce bitter?
The bitterness is caused by heat. Lettuce likes cool temps, where they don’t often get over 75F, if you don’t want them to get bitter. When the heat becomes more consistent, certain chemicals are created for flowering, and producing seed. This is what causes the bitterness.

How many hours of light does hydroponic lettuce need?
How Much Light Does Hydroponic Lettuce Need? Lettuce seedlings need around 18 hours of light during the day and six hours of darkness overnight to mimic outdoor conditions. The best way to provide this light is through fluorescent grow lights, which are ideal especially when you are first starting your lettuce garden.
How do you make lettuce grow bigger?
Lettuce grows best in loose, cool soil with good drainage. The addition of organic materials, such as compost or manure, will increase drainage, provide essential nutrients and improve your lettuce growing conditions. If you’ve had trouble with lettuce growth, consider purchasing a soil test kit.
What is the NPK ratio for lettuce?
The most commonly recommended phosphorus ratio for hydroponic lettuce is between 15 and 20 (for example, an NPK of 5-18-20).
Does water lettuce need fertilizer?
Fertilizer. In the event that water lettuce leaves begin to turn yellow, a lack of nutrients may be a possible cause. If the water lacks the right levels of nutrients, you may need to supplement with a fertilizer treatment. There are several different ways to fertilize water lettuce.
How do you maintain pH balance in hydroponics?
Make sure you use products that are formulated for hydroponic systems. For small systems or short-term results, you can add weak acids such as vinegar or citric acid. Automatic pH controllers cost more than pH up or pH down products but they keep the pH at consistent levels.
How often do you change water in hydroponic system?
