1. Ever-Bearing Varieties: These varieties produce two or three crops per year, typically in the spring, summer, and fall. While not strictly year-round, they can provide a longer harvest season than June-bearing varieties. Examples include 'Ozark Beauty' and 'Quinault.'

Selecting the right variety is crucial for maximizing your yields and ensuring a continuous supply of strawberries.

Nutrient Solution Management

The nutrient solution is the lifeblood of your hydroponic strawberry plants. It provides all the essential elements they need to grow and produce fruit. Here are some key considerations:

1. Nutrient Formulation: Use a nutrient solution specifically formulated for strawberries. These solutions typically contain a balanced blend of macronutrients (nitrogen, phosphorus, potassium) and micronutrients (iron, manganese, zinc, etc.).
1. p H Levels: Strawberries thrive in a slightly acidic environment. Maintain a p H level between 5.5 and

   6.5 for optimal nutrient uptake. Use a p H meter to regularly monitor and adjust the p H of your nutrient solution.

1. EC (Electrical Conductivity): EC measures the total concentration of dissolved salts in the nutrient solution. Monitor EC levels to ensure that your plants are receiving the right amount of nutrients. A typical EC range for strawberries is 1.8 to

   2.2 m S/cm.

1. Water Quality: Use clean, high-quality water for your nutrient solution. Avoid using tap water that is heavily chlorinated or contains high levels of minerals. Reverse osmosis (RO) water is often the best choice for hydroponics.
1. Regular Monitoring and Adjustment: Regularly check the p H and EC levels of your nutrient solution and make adjustments as needed. Replenish the nutrient solution every one to two weeks to prevent nutrient depletion and buildup of harmful substances.
