Curing and how long to keep jar open?

i only ask because when we FINALLY get a cold front thru here, nights are in the mid 60’s days in the mid 80’s and RH is about 60% avg. (even in January our outside RH is about 60%).
But i think i will do maybe one “jar” and keep a close eye on it for mold. But i like your idea.
Did you see the Twins pic? and they are doing good on the scrog that we “fashioned”. the new twins are growing … don’t know what happened to first Quads except for maybe that not shaking the bottle of FFBB fiasco? but glad i don’t have a complete black thumb. (sorry for divergent topic on this thread).
