In all honesty, the reason people think that good quality NZ sphag is so expensive is because the vendors in the US and Europe are guilty of artificially inflating prices. They see that other western vendors are charging exorbitantly high prices, so they jump on the bandwagon and match those prices to maximize their profits. (It's also traceable back to pretty much one single US vendor who started all of this...)
On the side of the growers, way too many growers simply pay the prices without question and just assume that it has to be that expensive. Because of this, and the fact that there aren't very many competing vendors outside of Japan and Korea who import this type of moss, the cost of the moss is being held artificially high.
While admittedly there is indeed a shortage of moss right now due to the current import/export slowdowns around the world, NZ sphagnum isn't normally that much more expensive compared to bark or other typical orchid media when you know where to get the best prices.
I often purchase my moss from Korea or Japan and prices are about
:
- 2A bales, $38 per kilo
- 3A bales, $48 per kilo
- 5A bales, $68 per kilo
- Loose packed hand selected 40cm strands, $18 per 100g bag
Bales are typically 3kg and one of them can remoss hundreds of plants.
In addition to that, there are ways to purchase moss directly from the harvester in New Zealand, and prices are even lower if you do that.
Heck, you can even get small bales of 3A and 4A from Amazon Japan, and they'll ship it worldwide.
Regarding the loose packed strands, western growers often call this 5A, but this is not 5A. These lose packed hand selected strand packages are graded by the moss harvesters as premium grade long strand, and are 1 or 2 tiers above 5A depending on the length. This sort of moss is not at all necessary unless you really want to make absolutely perfect mounds for judging. Normal 4A and 5A bales are more than suitable enough for daily growing. Personally I most often use 3A moss for the inside of the mound and only use 3-5 strands of 5A to keep the mound together on the outside. If I'm out of 5A, I'll occasionally use a few strands of cotton basting thread to keep the mound together.
