Source for COIR compost?

I'm going to be trying COIR, in combination with seaweed fertiliser, for my next lot of microgreens.

Can anyone recommend a good source for a small order? Say a single 70l bag.

I'm really quite surprised at how variable the prices are.

Thanks

    I've only ever bought the 10ltr blocks from Poundland. Don't think they have it in all year but usually by January once the garden stuff comes back onto shelves.

    That may be confusing.

    Are these compressed blocks? I have only seen those sold by weight, which then "expands" to say 50l.

    I've never heard of it being supplied in bags.  I've bought bricks from the Organic Gardening Catalogue for six years.  You can buy as many or as few as you like.  One brick makes, they say, 9 litres; I've never measured it.  They also supply nutrient granules to add to it.  Easy for storage, ready for use in an hour: less, if you use warm water, and no weed seeds.

    I found a photo of the actual block.  It does come compressed/dry and then adding water makes it to the 10ltr of soil.

    One big drawback with it,  never let it dry out, after the  first wetting as it's very hard to rehydrate. Commercial compost  have wetting agents in them.

    Thanks.

    It will be bottom watered/ fed microgreens, so I should be able to manage that.
