So I would often play with that depending on what temp I needed.\r\n\r\nWhile I do agree with the \"60-64F ambient is a good temp during active fermentation\" advice, I find that I get faster and more consistent fermentations if I keep the wort temp warmer as fermentation slows.  A condition where the wort heats to 68F, then falls down to the ambient of 62F can lead to extended or incomplete fermentations.\r\n\r\nI have been happy with [this seed mat + controller combo](https://smile.amazon.com/gp/product/B016MKY7C8/) I picked up from Amazon (there are other brands and combos that are similar).  I have used this to keep Kveiks and Belgians in the 80F to 85F range.  A mat and a blanket should be a cheap solution to keep your beer temp above the ambient temp as needed.","subreddit_name":"Homebrewing","author":"CascadesBrewer"},{"body":"Ventilation could definitely be a culprit, but my initial focus is on the temp. 22 degrees is pretty low, by getting the temp up around 26 you'll really speed up the growth (from months to weeks) and can avoid problems like wet rot (can be common when spawn time takes longer than 4-5 weeks because of the excessive moisture in UB bags). \r\n\r\nI normally incubate mine in a box with a small heating pad and a temperature gauge/thermometer. The box should be just big enough to fit your UB bags and the heating pad without the heating pad touching the bags. You just want the pad to be heating the air in the box, as the pad normally gets too hot for the UB bags.

They were planted both at the same time. The ones in the house germinated at about 7 days. The garage had almost no activity, not even a root hook. So I threw the heat mat under it with the thermostat probe dangled in the water reservoir through the little hole they have in the top that you’d normally place the extra water tank tube through. I set it to 85 degrees and after about a day you could see condensation in the domes. I measured the temp of the sponges and they were at around 82-84. All have sprouted and have almost overtaken the ones in my house in size.
