exactly how I do it. I say 60-90 mins cause to get up to 250 after I ash over it climbs really slow for me in the early morning. maybe cause I have it choked off too much when it's lid is closed but like I said one time I closed the lid and opened the vents too much and I was at 600 degrees and it was a mess getting it back down. but again love my egg. I have made some killer food on it. but I do want something automatic for my porch during the week vs going out to the pool house and setting up down there.Regardless of which way you go with the pellet grill, check out Malcom Reed’s video on getting the fire going in 10-15 minutes on the BGE. I’m assuming you went green. If you went red, there are also plenty of videos on the KJ, too. There’s also a great forum on Kamado cooking - Kamado Guru
Just hate to hear you struggling with your egg! I absolutely love my KJ!
