i use spawn bags all the time for sawdust blocks. i seal before i pc. it takes quite a long time for bags to cool off. by having it sealed, it's clean and safe.the filter patch does not allow much air to pass thru. you want to get most of the air out of the bag before you pc.you do need to pc longer with heavy bags. mine are over 5 lbs. each. if i do 3 at a time, i pc for 2 hours.even 1 at a time, i would pc for 1.5 hours. i experimented with 3 at a time. 1 hour turned green. 1.5 hour didn't, so i go 2 hours to be safe.for sealing, it's easy. try it on the top of a bag. depends on the bags and the sealer. test the seal by squeezing the bag with air in it if it doesn't leak, ok. raise the temp till it melts thru the bag, then turn it down a bit. on mine, it seals good at 3.5. i only double seal if it looks like i didn't get it nice on first try.bags get kind of brittle after being used. not worth trying to use them again. they're cheap enough. i use sawdust spawn to innoc, but i have done lc without injection ports. inject and tape worked fine. try bags. good luck.
