Use the corresponding to enemy glimmer code: Cabal - Resupply Codes Fallen - Ether Seeds Hive - Wax Idol Vex - Blue Polyphage Farm the area. You may get some items that can be turned into the Cryptarch for 200 Glimmer. They are - Cabal - Network Keys Fallen - House Banners Hive - Silken Codex Vex - Axiomic Beads Put these into your vault. When glimmer is needed, take them out and use the corresponding Glimmer code item before handing them in. Try not to have different pieces to hand in, as it wastes a lot of glimmer addition codes. Hand them in, repeat strategy.
