My level 30 Breton has 155 pounds of alchemy ingredients ATM.

I have around 300 pounds of ingredients I believe. I hoard all of them. Have to when leveling Alchemy. It can be a grind.

Yep, I store a lot of stuff. Not used much of it (I'm waiting til my Alchemy perk tree is a little fuller) but I have collected a lot of ingredients just in case I might need them for a potion or poison. I have mixed and matched a few different potions, but I'm sure I have many more to discover so carry a lot with me.

My carry weight would be over 1,000 if I only had ingredients in the inventory.
I have them stored away and I'm not on the xbox. I'll get the exact number tomorrow.

About 80 salt piles, 40 longfins, and 40 spadetails. 1 spriggan sap and 1 blisterwort.

= Player level 85, alchemy, smithing, and speech level 100, and a kick-butt long bow.

I used to hoard hundreds of ingredients, but since rehab, have I learned to limit myself.

At first I hoard everything, but when I discover their effects I hoard only the ones with effects like paralysis, invisibility and other big money effects.
