| Dill 🌾 | 0.8 – 1.4 | 5.5 – 6.5 | 60 – 70 | 200 – 500 | Ensure moderate spacing; responds well to consistent nutrient levels. |
Making Our Own A & B Nutrients 🌟
At Quality Plants & Seedlings, we create our own A & B nutrients to provide the best hydroponic solutions for our plants. Here’s how it’s done:
- Part A 💧: Contains calcium nitrate and trace elements to support strong plant structure and healthy growth.
- Part B 🌱: Includes magnesium sulphate (Epsom salts) and other essential nutrients like potassium nitrate for vibrant foliage and fruiting.
🔧 Mixing Tip: Always dissolve nutrients in separate containers to prevent reactions, then combine them into your hydroponic reservoir.
🌡️ Storage: Keep nutrient solutions in cool, dry conditions to maintain potency and prevent clumping.
