Shit, and how I deal with it.
As you can see here, with this seasons abundance of moisture 'shit' is just incubating at an alarming rate. Couple that with my ignorance to a well foliated strain, and you have bud rots dream. No that's not a new strain, it's the name of a cultivator's worst nightmare.
Look at this yellowy brown foliage. This is Botrytis for those of you whom have not had the disgust of finding this in your crop. It can devastate the whole crop in days if it isn't caught early. Once it makes itself known, it can't be gotten rid of. The worst of it all, it can make it all the way into the harvest and even ruin your cannabis while its curing.
Here is another angle at it. Notice the browning of the stem. This is how it works its way into your plant. The only remedy I know of that does not involve chemicals is to cut it out.
You do not just want to remove the affected bud node / branch, you really need to cut back to ensure the Botrytis is less likely to spread through the plant. I usually cut two to three bud nodes back, unless I didn't catch it early, then I may remove branches. Anything to buy a bit more time for the plants quality buds to ripen. A lot of sources I have read researching on this issue suggest to take the plant down immediately. I could see this being an absolute must for an indoor grower, however for the outdoor enthusiast, I look at 'shit' as just another opportunity to overcome.
So how does Botrytis occur? From what I have read, Botrytis is a fungus that occurs in different ways, overly wet conditions, susceptible genetics, in adequate sanitation, and my mistake this year, left behind decaying peciolos(leaf stems). That's right, everywhere I have incurred Botrytis this year has been in a location where a inch long brown decaying leaf stem had remained from an earlier pruning.
Learn from my mistake, BE SURE TO REMOVE THE ENTIRE LEAF STEM. The left behind peciolos actually began to decay at their tips. However the part of the stem closest to the stalk was still very much alive. This decay actually worked its way into the stalk before the peciolo falls off naturally. The added moisture this season and dense foliage actually contributed to rotting the peciolos, instead of them normally just drying up and falling to the ground like I am accustom to.
I guess there is still some good here, I learned something about proper pruning thus allowing me to spit some knowledge your way. I think unless an indoor grower is really lacking moisture control, sanitation, Botrytis is more of an outdoor growers issue. Not saying it won't happen, just that indoor growers usually have more control over the humidity / rain / dampness their crops endure.
My silver lining here is two things. First, I get to sample a bit of my crop because I cut off more than the affected area. Though not fabulous, this is a sweet treat. Second, The ONLY plants affected as of right now are the Snow Whites. Both these plants were just loaded with foliage and I know they held rain periodically.
I hope the other strains I have this year stay Botrytis free. As of now I think I will be ok on them as the Vanilla Kush only has a couple weeks to go and the JCExtreme NoName is such a stretchy strain the moisture holding ability of its foliage is practically non existent.
Well tokers, until next time Toe, Toe, Toke it up!
