Bud rot indoors? What causes that? RH?
there are a few things that can contribute to bud rot indoors IME,
here are the ones I have experienced.
genetics are one. some strains just seem prone to it, especially
ones that grow huge tops.
high degree of temperature fluctuations from day to night are
another. the more the temperature fluctuates, the more the humidity
fluctuates as well.
leaf die off is a third cause that i have encountered. dead leaves
are fungal food, period. that's the role of fungus in the ecosystem,
decompose material that is rich in lignin and cellulose.
