The 5th tier on Riding Intrinsic will mark resources on the map while you’re on the kaithe. And as neooffs said, the resources tends to spawn in specific places. For instance, you’ll find a bunch of Yao Shrubs around snowy area like Titan’s Rest. Connla Sprouts near sources of water. You can look them up on the Warframe wiki.

I also break every resources I spot when I’m on my way to something, so I’m slowly building up my stock over time. It’s a bit tedious but I’ve spent an average of two hours when I play Duviri Experience. I get easily distracted by all the side quests, LOL.

each resource spawns on specific places and decrees give some aswell

I might be biased because I always run resource boosters but I didn’t have much problem getting them other than Pathos Clamps since I buy every arcane in the shop

I had a few random sessions of Duviri Experience. Just exploring, doing puzzles, sidequests and so on. Somehow, I ended up with hundreds of resources of each type.

Warframe thought me not to focus on the grind and just do what I find fun and I somehow arrive at the same destination.

Get the rank that shows them on minimap and the teleport ability. Also run duviri experience it solo as sometimes you will load in to a zone with no resources as theyve been harvested before your arrival.

For jaws specifically you can just spam the same fishing spot over and over, then do a different mission after to save your resources.

Different resources can be found in different locations around Divuri too. https://i.redd.it/drfa1381tdwa1.png

If I need something specific I usually jump in and scour that area for the resource I need :)

But the majority of my resources have come from casually shooting bushes during Pathos Clamp runs or during the multi-hour sessions in “Divuri Experience” running Enigma puzzles. The 5th tier Riding Intrinsic is pretty useful for finding resources in areas as well :)
