I ordered coir seed pellets, (first time I have used them), the order process was easy and the pellets arrived promptly. Reading the instructions it suggested using a covering of vermiculite and indicated that this could also be bought from green gardener, however I could not find any reference to the item on their web site. I sent an email via the web site pointing out the issue and if they could advise. I received a very prompt response explaining the item was currently out of stock but they offered to notify me as soon as it came back in. In the meantime I have bought vermiculite from the local garden centre. So all in all a very positive experience with green gardener. Its too early to tell if the coir pellets will prove better than conventional seed sowing but my initial feeling is that they are much easier. I am doing a side by side trial as you will see from the photo,
