About this product
A straight magnesium sulphate of horticultural grade, supplying magnesium and sulphur with no nitrogen, phosphate or potassium attached.

No N, P or Kcorrects magnesium without disturbing the programme
Sulphur included32 % SO₃, immediately available as sulphate
Horticultural gradefully water soluble, for nutrient solutions
Straight fertiliserone job, done without side effects
