Pro Cal 4 L
Pro Cal 4 L is an exceptional additive of calcium, magnesium and iron. Pro cal is important for growing on coconut substrate as well as for hydroponic systems.
It is used at all stages of vegetation, growth and flowering. It is not added in the last week of flowering as the Green Planet fertiliser programme adds Green Planet Finisher and Liquid Weight in the last week as well as enzymes with water.
Type of fertiliser:
- NPK: 2-0-0
- vegetation/growth: 5ml per 4 litres of water
- Flowering: 7ml per 4 litres of water
Do not add it during the last week of flowering!
WARNING! Over-fertilisation can harm soil and plants! Store in closed and dark places at room temperature! Keep out of the reach of children!
