I've really only burned Greene Team Gold and Somersets in the last two years and the last year or so its been mostly Somersets cause I can get them easily/regularly at the Menards near me and for a fair price. Picked up a ton on a Sunday about a week ago ($179). Burned for 4-5 days, on both Room/Stove temp mode and noticed my ash pan was almost FULL. I thought, man, that seems pretty fast to fill my ash pan. In past seasons, whether I burned Somersets or Greene Team, I could always burn for at least a week and only have half an ash pan. Now, I'm having to empty the ash pan in between my weekly/bi-weekly deep cleanings. And the ash seems fluffier, where in the past, with the Greene Golds, the ash was very fine. In conclusion, I've definitely noticed the increase in ash produced by the Somersets that I just purchased. I'll try an experiment and dig deeper into my stash to see if Somersets from last season are any better than the ones I just purchased. More ash = less purity in the pellet?
