There is a new product in the shops from the Gardening Success range called "Seed Blanket".
This product is just fine grade vermiculite, which is find, good even, for covering seeds to assist germination. However, one can buy vermiculite for around £8 for 10 litres, but this product is charging £2.99 for just 600ml - which makes it six times the price!
Vermiculite is excellent for covering seeds: it reduced temperature fluctuations, holds moisture and is sterile, so fewer problems with damping off and fungal issues. It is also very light, so seeds to not need to waste energy pushing through the covering.
But why pay six times the normal price for a small quantity in a fancy tube?
