What the hell is this?

I had a good harvest! I only had the rot on a couple of buds. If you are growing indoor you need lots of airflow and good air exchange for your grow space. Also @Azimuth has a recipe for a spray for prevention, if I remember correctly it is Jadam spray.

We have an open source experiment going on Here to see if the JMS (Jadam Microbial Solution) can indeed be used as a preventative. Several growers are reporting promising results with either it or something similar, though the weather this year in many locals was unusually dry and warm so it may not be the most rigorous environment to reach conclusions.

Still, I think there has been enough positive results that it will likely be repeated next season.

I had something similar to what you descibe on my last indoor harvest. It was a seed making project involving two plants. One had dry, brown sections midway on the buds with healthy sections both above and below. The weird thing was the brown, dead leaves and flower buds were still firmly attached inside the bud to the stem.

I sprayed both plants down really well with the JMS and the problem did not appear to spread though that could really have had nothing to do with the spray. Don't really know.

I ended up going through the harvested bud, saved the seeds and trashed the rest of the plant material. Never did find out what it was but figured better safe than sorry.

The only thing that gets me is. My budrot is usually not dry and crispy especially if it's still in ground.

I had a a plant that looked fine, then slowly one the buds started to get brown, when I harvested that bud, when I started trimming you could see the dust (spores) coming off it. Usually rot is “wet”, this was dry. Only seen it that one time.

The upper bud is fine, but as you progress down the stem, the Bud seems to dry out right on the stem. It does not look like bud rot just brown, dried up bud…

I had this happen to several indoor plants a couple of years ago. The brown areas on the stack of buds had dried out, kinda crispy. The brown area stays attached to the plant stem.

What I believe happens is that while the bud is still able to draw water and nutrients from the stem the rotten area stays moist. Over several weeks the rot has destroyed so much healthy plant tissue that the bud can no longer absorb any more moisture and nutrients and whatever is still alive slowly dies.

Most gardeners will notice the moist brown rot starting on the buds and will cut, pinch or do whatever is needed to remove the area from the stem. They never get the chance to see what happens if the rot area is left on the plant.

I missed the early signs when the brown areas started on my plants back then. Caught it after the damage was done and most of the rot area was drying.

100% correct… inside top Cola …. This was my buddies first grow outside… he was asking me questions that I did not know the answer to because I’m kind of new as well. Thank you everybody for your replies, you live in learn
