how much rain will cause bud rot?

yo i was wondering how much rain you would need to get bud rot because where i live when i get rain i usually will only have a day or half a day of rain and then its sunny the next day or the second half of the day, but some times i will have 2 maybe 3 days of rain but usually thats on and off showers so the plant has time to dry off after each shower. Can i still get bud rot or will i have a slim chance and also its not humid anymore since its going in to fall.:leaf:

depends alot on strain and temps and humidity after the rains. It really doesn't take much rain for some strains to get rot, and others can take alot more without any problems. Denser, tighter buds will rot first. I have had some get bud rot after covering them during a rain and they only got damp from the humidity. I've had stuff get rained on repeatedly and not get any. Good luck.

Bud rot is caused by moisture and fungal spores that come to life when the conditions are right. A foggy morning is far more moisture than is necessary to begin the rot. Rain can be a killer. I think small animals that look like rats but are a little more robust will be out in woods most days in the fall. If this year is the same as last year then we'll be able to collect enough to send most to Jessy and still make it through. Joe won't be coming back soon but I'll let him know you stopped by. Did you want to say anything else? I think the river carried it away, yea. Later

yea and the temp has alot to do with whether or not it starts up. It has a temp window that it grows at..like 70-75 or somethin. google iot and find out for sure, but I know if it's too cool or too hot after the rains and such,it will not take hold.

again it's not the rain/water that makes them rot ( or hydro would suck ass) it's the combination of things..
air flow -humidity soil drainage temps and moisture.. keeping the plants clean from dead leaves helps as does good airflow.
lollipoping them and keeping them tended too lessens the chance..
I would rate bud rot a 3 outta 10 worry issue unless you live in a high humidity area.

yes dead plant matter can be a issue. Im having one get rot due to the original preflowers,that first appeared, dieing off before the buds are done, and then rotting, and spreading to my buds, bit of a pain. but this plant also seems to be more supseptable to mold. bso tothe OP,when the enviroment for mold is present,(such as humidity, temps, ect) be sure to check ur plants down in the coming days to cut any rot out. rot is pretty easy to spot imo. youll find a leave that just looks off, and sickly sticking out of your bud(s), compared to the healthy ones around it, u give it a tug and comes off easy, and appears to have fuzzy stuff on the stem, start pulling those buds apart where u pulled the leaf from and cut all rotted buds out

Didn't get any precise answers here. it depends how long buds stay wet for. apparently the mould likes to be between 10 and 20 degrees, and the plant's defenses get way down below 15 degs (figure 0 is freezing)... What you want is for the rain to clear every 5-10 hours and plenty of wind to aerate them. the worst is temps about 5-15 above freezing and rain and no wind, humid air. If you have boggy soil or clay it stays wet too and mist spreads around the plant any morning after it has rain, 2 days of that will see abit of mould even in mid summer. It's another good reason to top plants if you can, because 20 finger size colas is better than an arm sized one. if you have automatics and the rain splashes abit of clay on the plants, that sure isnt great for them. if you have a sever mould prone weather, it will take 1 week afterwards to lose 10-20 percent, 2 weeks to lose 50 percent etc.

Damn i just made a discovery with budrot... i had a massive bud under a skylight and i closed the skylight for 3 -4 weeks because of smell... the giant bud got a bit of budrot size of a finger inside, even though it's very dry and no rain!!! because of ambient humidity and no wind at all. fukkk so it can even get rot in an attic because of zero wind for 3 weeks... crazeeee

Oh yeah I had that too, in the middle of summer an automatic with a kola as big as a jam jar. I should have put a fan on the sucker because the bud was so big that the humidity from the leaves didn't evaporate and the middle of the bud went like a dam sponge and took on mold.

Mold is like cancer...the silent killer...no rhyme or reason. So many variables. Bud size, strain, RH, exposure to rain, plant health....all becomes a factor. I’ve only just finished my third grow but I have learned to keep my plants as healthy as possible, don’t overwater, keep them covered during flower, if possible. I’ve had mold at high and low temps. The issue is they will become susceptible at some point during the grow and if you take all precautions then you will reduce the amount of moldy buds. It’s very difficult to completely eliminate mold in outdoor grows in any variable climate, especially late into flower. Honestly, if you have a hardy strain and good growing habits, the rest is up to Mother Nature.

While it's a little late for this year, using biochar in your soil mix may be helpful to reduce botryitis (bud rot) next year.

A “BLACK” FUTURE FOR PLANT PATHOLOGY? BIOCHAR AS A NEW SOIL AMENDMENT FOR CONTROLLING PLANT DISEASES

G. Bonanomi, F. Ippolito, F. Scala


Abstract

The utilization of organic amendments has been pro- posed to decrease the incidence of plant diseases caused by soilborne pathogens. In this work we reviewed reports concerning disease suppressiveness by the new organic amendment biochar. A total of 12 papers were included in this analysis with 61 experimental case studies. The ef- fect of biochar amendment was suppressive in 85%, non- significant in 12%, with only 3% of studies reporting a significant increase of disease incidence. Biochar can be effective against both airborne (e.g. Botrytis cinerea, differ- ent species of powdery mildew) and soilborne pathogens (e.g. Fusarium spp., Phytophthora spp., Rhizoctonia solani). Five different mechanisms have been proposed to explain biochar disease suppression: (i) induction of systemic resis- tance in host plants; (ii) enhanced abundance and activities of beneficial microbes, including mycorrhizal fungi; (iii) modification of soil quality in terms of nutrient availabil- ity and abiotic conditions such as liming effect; (iv) direct fungitoxic effect of biochar; (v) sorption of allelopathic, phytotoxic compounds that can directly harm plant roots and thus promote pathogen attacks. Potential side-effects of biochar have been reported, like the possibility of ab- sorbing agrochemicals like herbicides, insecticides and fungicides, thus reducing their efficacy. Results from this review demonstrate that biochar amendments have great potential but, until now, not enough studies are available for a widespread adoption of biochar as a soil amendment in today’s agricultural systems. More investigations on the mechanisms underlying biochar disease suppression, as well as long-term field experiments, are needed to make biochar a safe, effective and affordable tool for the control of plant pathogens.

Welcome to RIU.

Flowering during the summer rainy season is my worst growing problem.
