Good quality product, arrived on time. Thanks.

No more green slimey mould on my planters. Saved one of my 2 Lilac trees from last years blight arrack too and I have a bit left.

Suitably contained well packaged which made for safe and secure transport and storage.Was used to grow Copper Sulphate Crystals for child education of crystal structures.Excellent experiment performed with the crystals and the aim was successfully achieved.

Bought this so we could grow awesome crystals in a home lab. it contained quite a lot of insoluble material which we needed to filter out, but the dudes are growing now....

Seems OK

Bought this to try and combat rust on my broadbeans. Think I may have just killed the whole plant instead. Use sparingly!!

Thanks to the EU you can no longer buy a solution to eliminate blight from vegetables etc. My partner is a chemist so purchased this as part of the process to make a solution and it worked and we now have lots of potatoes.

I used it diluted in water to paint onto a bare concrete path having previously done the same with iron sulphate. The result after some weathering is a bluey brown stained path that mimics the stonework of the house and I am very pleased with it.
