Maybe I just had a bad bag of RO. What was happening didn't make sense. It was cool and windy yesterday but when I added briquets, the temp. came up to 275. I am new to the WSM but have been smokin for alot of years now. It should have burned hotter than it did. I am still learnin the WSM and controlin temps, but loaded with RO and all vents wide open, what was going on? It just didn't make sense. Maybe I'll give it another try with a different bag of RO. Thanks for everyone's input on this.
