Vermiculite- 2litres

Vermiculite is a naturally occurring hydrous phyllosilicate mineral, it undergoes significant expansion when heated. It is lightweight, non-toxic and does not deteriorate over time. Like LECA it has a neutral pH.

Benefits of Vermiculite:

-Improves water retention, it soaks up the water and expands, and as the soils around it dries out the water is released to keep the soil hydrated.

-It can absorb up to 4 times its volume of. water.

-It has great insulating properties, making it handy to protect seedling roots.

-Can be used to germinate seeds (we recommend using a finer grading than this particular variety)

-Attracts various plant nutrients such as potassium, magnesium and calcium.

-Aerates soil
