- Make sure to refill the water tank regularly to ensure greater stability in plant food concentration. For optimum growth, we recommend not letting your water level go below 50%.
- Change the water with new water and plant food at least every 30 days to maintain a healthy pH balance. >>Learn more about refreshing the tank.
Plant food and germination:
- Plant food can hinder germination if added before you see true leaves.
- It can also burn the tips of your plants' leaves if it becomes too concentrated. Make sure you do not add more than the recommended amount of plant food. Plants can overeat and that will impact their growth.
Topping off the tank with a mix of plant food and water:
Can I use organic plant food?
Mineral plant food provides the same nutrients as organic plant food, but without generating excess waste that will clog your pump. Since there is no soil present in a hydroponic setup, mineral plant food is always preferred because it is cleaner and will prevent biofilm from developing in your tank and columns. Your plants will still be organic, so no worries!
Some Gardyners have received scoops that amount to more than a teaspoon due to supply issues. The guidelines above have been approved by our Master Grower. Because plant food concentration is measured on a spectrum, these guidelines will work for both a true teaspoon as well as a larger scoop. The true teaspoon will put you at the lower end for ppm, and the larger scoop at a higher end. Both will keep your plants healthy and happy!
