    The perlite is necessary because your strawberry plant will need a growing medium to hold it in place steadily. This makes absorbing nutrients more effective and keeps the crown of the plant out of the water.
  • Question
    I'm growing my strawberries using the Nutrient Film Technique (NFT), and they're very small. Otherwise, the plants look healthy, their Electrical Conductivity (EC) is 1.8, their pH is 6.2, and they get 6-8 hours of sunlight each day. What am I doing wrong?

    The strawberry plant variety you are using may have a naturally smaller fruit. If not, consider increasing the amount of sun exposure your plants receive each day. This may help your strawberries grow bigger.
  • Question
    In step 9, do you immerse the whole plant or only the roots?
    Community Answer
    Only the roots. You don't want excess moisture on the leaves, as it can cause disease.
  • Question
    I can't buy nutrients at my location. Can I make own nutrients for hydroponics?
    Community Answer
    You can make your own Miracle Gro at home. Most recipes online require Epsom salts, ammonia and baking soda along with a few other ingredients.
  • Question
    Do I need to use a bubbler to put oxygen in the water?
    Community Answer
    No, but doing so will have a big effect on rate of growth. Roots need oxygen as much as they do water.
  • Question
    What nutrients do I need to grow strawberries?
    Community Answer
    Purchasing a nutrient solution at a hydroponics shop is the best way to ensure you will have all the right nutrients for your plant. According to Garden Culture Magazine, for a fruiting nutrient you will need: 8.00 gr Calcium Nitrate – Ca(NO3)2 2.80 gr Potassium Nitrate – KNO3 1.70 gr Sulfate of Potash – K2SO4 1.39 gr Monopotassium Phophate – KH2PO4 2.40 gr Magnesium Sulfate – MgSO4 * 7H2O 0.40 gr 7% Fe Chelated Trace Elements

  • Question
    How many strawberries will grow on average per plant?
    Community Answer
    This depends on the variety. The average is one quart of strawberries per plant per year, but growing conditions can alter how much fruit your plant produces.
  • Question
    How do I increase the yield with controlled LED lighting? Can I set my timer to specific times to be on and off to speed up the growth process?
    Community Answer
    Most plants are on an 18hrs on/6hrs off cycle for the vegetative state and 12hrs on/12hrs off for the flowering state. Either of these light cycles should be OK for strawberries.
  • Question
    What is the point of the air stone when you use wicks? I fail to see how micro-sized oxygen bubbles are going to go up the wicks to the roots.

    The air in the reservoir is to prevent anaerobic bacteria from taking hold. In practice, if you are replacing the solution and rinsing the reservoir regularly, it can be omitted. If you are like most people and remember to do that maybe monthly, the air stone is a good investment.
  • Question
    Is each plant grown in a 5-gallon bucket?
    Community Answer
    You can grow quite a few strawberry plants in one 5-gallon bucket. If you don't want that many, opt for a 3-gallon container.
