on a cold rainy day Bud Rot can and will ruin a whole bud ,overnight is all it takes so you really have to be proactive with it check often cut below infected area save good buds toss any with br on them, if at home cover them if you can at night and uncover them in morning , Im heading out to GH now at 6 13 to start fans and heater , if you cant cover them shake them as early as you can , outside we only grow where we get early sun this helps good luck
