Liquid and solid plant food solutions

Plants grown in water require specific minerals that soil usually provides naturally. This catalog features A&B nutrient sets that you mix into the water tank to support growth from seed to harvest. These solutions are balanced for vegetables, fruits, and flowers.

Proper nutrition prevents yellowing leaves and stunted growth. These listings provide the essential elements needed for hydroponic environments where roots are submerged or misted.

Essential supplies in these listings

You will find individual nutrient bottles and complete starter kits for various system types. Some sets include replacement sponges and baskets compatible with brands like Aerogarden or MUFGA.

Managing water chemistry

Maintaining the correct pH level is necessary for plants to absorb nutrients effectively. Use the pH control kits from GIDIGI or Gardyn to keep the water between 5.5 and 6.5. If your plants look unhealthy, check the nutrient concentration and the water balance first.

When starting a new batch, follow the mixing instructions on the A&B fertilizer packaging. Over-feeding can be just as harmful as under-feeding, so use the provided measuring tools.
