Spooned Zenyte

Title, spooned my first zenyte on 80kc, is sand/giant seaweed still best method for training crafting? I’m looking at sandstone for 20k sand, farming 3k giant seaweed, and then crafting 2kish astrals. Seems like there should be a better way, but I’m unaware. Any ideas or suggestions would be greatly appreciated.

Update: Spooned another Zenyte 30kc later. Suddenly this crafting grind got significantly longer.
