The garlean guys up by Castrum Novum In Mor Dhonna drop various clusters. They are around level 54 though can be soloed but would help to take a friend. I'm sure there are other places you can get them but I was there last night and noticed them dropping regularly.

You can also get clusters from Elementals. They tend to pop up in a single spawn at random locations with a low proc rate though. There are a couple of leves however, that do have elementals. I know one of the Flames GC quests involes poking elementals and ive gotten a few clusters there.

Apart from that you can buy them from NPC at hamlets though I think they are around 21K

You can earn clusters from gatherer leves, too
And in Black Shrouds there are some caves with elementars
