## Questions & Answers

**Q: Once i apply this to my heavy clay soil will i ever need to keep buying this product ? or is it a buy once fix ?**
A: My veg patch is 4 metres x 4 metres I turned it over and spread 25kg over it and then rotavated the area, three days later I did the same again. The clay soil had definitely improved and was more manageable. Cannot see the need to add more gypsum.

**Q: Does this bag of gypsum come in a cardboard box?**
A: No it came in a bag, it’s very heavy

**Q: Is the bag plastic or paper please? I'd want to store some for later use**
A: Paper / thin card bag same as plaster. Was delivered in a plastic bag though so I’ve been able to store it without issue

**Q: What is the magnesium (Mg) content of this product, if stated?**
A: Sorry the spec sheet doesn't specify the Mg. It is Calcium sulphate dihydrate, 85% minimum gypsum purity, 7 pH and its Chemical Composition is CaSO4.2H2O.

Good delivery time, great that this can be delivered as had no idea how else to source locally . Using to mix with my clay soil as advised it will help with water clogging. If using of this it’s meant to be a game changer, stop using sand or gravel, they make it worse!
