Making Our Own A & B Nutrients π
At Quality Plants & Seedlings, we create our own A & B nutrients to provide the best hydroponic solutions for our plants. Hereβs how itβs done:
- Part A π§: Contains calcium nitrate and trace elements to support strong plant structure and healthy growth.
- Part B π±: Includes magnesium sulphate (Epsom salts) and other essential nutrients like potassium nitrate for vibrant foliage and fruiting.
π§ Mixing Tip: Always dissolve nutrients in separate containers to prevent reactions, then combine them into your hydroponic reservoir.
π‘οΈ Storage: Keep nutrient solutions in cool, dry conditions to maintain potency and prevent clumping.
