Personally i've tried some of alternative QN mods like markers (which is buggy and/or don't work), and laser shooting nirnroot (not really lore friendly), and decided to try my own spinn-off of this.

Basically, this mod will simply reduce the number of red-weed you need to collect and deliver, to finish the quest and get your reward.

There are two version of this mod:
1. You will need to find only 10, instead of 30, which imo, is totally lore friendly and still very simple enough without markers.
2. You will need only 1 plant, which is located in the exact same room, where the quest will start, for those who really really hate the quest.

It is likely, that you will need a new game save, but not necessarily.
