Nutrients are liquid fertilizer readily absorbed by the plant, provided to the plant directly via the roots. You will need to create a balance based on your water (is it hard or soft? or are you providing rainwater?).
All nutrients will include calcium nitrate, potassium sulphate, potassium nitrate, mono potassium phosphate and magnesium sulphate as these are essential for plant growth.
We suggest you take some time to research your particular needs. Our range of nutrients are all top quality but you may still need to undertake some experimentation.
