Well, you have to have some discipline. Don't let equipment pile up--since it doesn't stack, it really eats inventory. Also, it can help to not hold on to HQ. It's better when every thing in your inventory isn't doubled because the you have the NQ stack and HQ stack. HQ mats are a crutch anyways..as you level you should be able to HQ your synths without HQ mats.

Which to keep depends on your level in comparison to the material's level. I found it best to keep only the HQ and sell NQ items as long as they were in the highest tier available for recipes that were still difficult to synth, but then to switch to keeping only NQ and selling HQ once I leveled past it enough to reliably make HQ components from NQ materials. But yes, it definitely helps with space if you're keeping only one or the other at any given time.

That switching which to keep pattern is simple enough for things like logs and ores, where there are only a few tiers and a new type at each tier, so they're not hard to keep track of. It's a pain, though, for things like cooking ingredients or reagents, where the wide variety of items makes it a lot harder to keep track of what tier they each came from and what they're used for. That's where I have the most problems myself with inventory bloat. I never seem to be able to keep track of which ingredients and reagents are useful enough to keep so I end up keeping all of them except for those the Material Supplier offers.
