Harvesting - when and why??

[Agewen]

As a new player to eq2.. I was searching to try and find a harvesting mod..

What I was looking for is a harvesting mod which will also tell me what "a root lvl 1 -9" can help me build.. I know with the specialization of classes down the road, I dont' really see the point in harvesting everything I come across and then having to double check to see if it's one compenent in my recipe book ..

Any thoughts/mods/suggestions to this?

Thanks in advance
