Top Crop Top Lemon pH– – Citric Acid Based Acid pH Corrector for Irrigation Water

Frequently asked questions

• What is Top Crop's Top Lemon pH-?

  It's a concentrated liquid citric acid solution formulated to acidify irrigation water and growing medium. Besides adjusting pH, it promotes greater microbial activity in the soil. It's the natural alternative to conventional acid correctors.

• What formats is it sold in and what's its concentration?

  You can find it in a 1-litre or a 250-millilitre format. It contains 41% citric acid monohydrate, so a very small amount adjusts large volumes. Choose the size based on your grow's watering schedule.

• What dose is recommended depending on the water type?

  The recommended dose is 0.2 millilitres per litre for hard water and 0.1 millilitre per litre for soft water. Before applying it, always check the values with a pH meter. This way you adjust exactly what your water needs.

• Can it be used to clean the irrigation system?

  Yes, it can also be used to clean drippers and irrigation pipes once the grow cycle is over. It makes it easier to remove limescale build-up and prevents blockages in the pipes. For this use the manufacturer recommends 0.5 millilitres per litre of water.

• Can it be used throughout the whole cycle?

  Yes, this concentrated solution can be used throughout the whole grow cycle and in any medium. It also lets you adjust pH before spraying your plants with water. One single product covers both watering and spraying.

• Does it affect microbial life or nutrient balance?

  Quite the opposite: its composition regulates pH while keeping the soil's microbial activity levels stable. Also, unlike other acids, it doesn't alter the proportions of nitrogen, potassium and sodium in your crop. It also makes it easier for nutrients to break down so the roots can absorb them better.
