Bud Rot: The Killer That Works From the Inside Out
Of all the ways to lose a crop, this is the cruellest, because it waits until the very end. You have done the whole long summer, watered and fed and fussed, and now the colas are fat and heavy and a week or two from the chop, the finish line close enough to taste. Then you squeeze a big top and it gives, soft and wrong, and you pull it open to find the horror at the core: a nest of grey fuzz and brown mush where the densest, proudest part of your best bud used to be. Botrytis. Bud rot. It hollowed out your winner from the inside while the outside smiled at you.

Why it goes for the best buds
That is the sick genius of it. Bud rot loves exactly what you spent all season building: the fattest, densest, most tightly packed colas, because deep in that dense flower the air never moves and the moisture never leaves, and that dead still damp pocket is a five star resort for the fungus. Add a cool humid night, a rogue rain shower on a maturing outdoor plant, dew that sits in the canopy till noon, and you have laid the table. It starts as a single browning sugar leaf or a limp patch on a cola, and by the time you see it the rot is already eating outward.
Move the moment you see it
There is no cure, only removal, and it is a knife job, not a spray job. The second you find rot, cut it out. Take the whole affected section well back into clean healthy flower, get it out of the grow space entirely, and do not let that mush brush against a single other bud on the way out, because every spore you scatter is next week’s outbreak. Be ruthless. A cola you hesitate over is a cola you will lose anyway, plus its neighbours.
Then attack the conditions, because rot is a humidity crime. Move air through the canopy, run a dehumidifier through those cool damp nights, and open dense plants up so wind and light can reach the middle. Outdoors, shelter maturing plants from rain and shake the water off after a storm, because buds that stay wet are buds that turn. And when a plant is ripe and the weather is turning against you, take the win: an early harvest of clean dry flower beats a heroic wait that hands the lot to the mould. The grower who checks the dense colas every day in late flower is the grower who still has a harvest when the rot comes hunting.
