Drive by Buckshot. Hey my dehumidifier runs 24/7 almost here in Oregon. Around here seems you get up over 50% RH, PM will nail ya every time. Bud rot is a soil born also, and around here them spores run amuck. Don't take much for them spores to find a nice mature bud and really rain on your parade. Myself I don't reuse my soil, I
donate it to a local community garden.
But next year I plan on using some of this to prevent hopefully, some of them spores,
PRO?MIX BX Biofungicide & Biostimulant - Enriched peat-based growing medium
Suppose to help with afew of the molds and fungus like Pythium, or Fusarium which both are soil born. Gray mold, Botrytis, is some nasty stuff. Nothing I hate worse than going at back to look at some colas and seeing that acouple dead looking withered up leaves growing out of my top cola. You give them the slightest little pull and they pop off in your hand then you see that sick brown looking center. Opp's sorry guess you can tell I've dealt with it a time or two. And I still haven't found anything that really works with it and 'cure's' it And I've tried the book. Oregon, well coastal Northern Oregon, has some wet ass weather that's for sure. And it hits right at prime buddage time of the year. All I can do it cut the offending buds away and watch her close to repeat, Sucks.
Hope you don't mind but I had a pretty good picture of some bud rot so I'll throw it up there. It was on a indoor plant. Since I keep my humidity under 40% I haven't seen it again but some really thick dense buds are pretty moist inside
Hope you get that problem gone.......... Keepem Green
