First harvest — rain advice?

[Mrs. Weedstein]

Any advice on pre-harvest treatment of outdoor plants growing in Oregon, where it will soon rain? I am too cheap to spend a lot of money on greenhouses or stuff like that, and the plants are too big and unwieldy to cover up each time it rains. Plus, it gets windy. Does shaking afterward usually do the trick? Any other tips?

Good luck . . . I have not heard anyway to battle bud rot in the conditions you are about to face. Pray for a dryer than normal fall!

Shaking plants off will help a little but wont "do the trick." Not really anything you can do now other than pray the weather gods are kind.

Look for discolored leaves that penetrate your buds. Sometimes they can be removed before they bring mold into your buds. If there is mold inside your bud, spray the mold area with alcohol, then remove the infected area. Then another spray at the site where the mold was. Try not to spray good buds with alcohol, might dissolve the resin. Shaking a plant that has active spawning mold spores might not be a good idea as that's how they travel....on the wind.

Don't go touching your good buds with the same hand or tool you used to remove the moldy stuff either.

Nothing can be done, just observe you bud and chop ASAP and pray you have a dry fall.
Windy is good though, it will help dry the bud.
Good luck

If it sets in, chop and run. Better to have bud than a bag of mushy mold . . . Make you cry for sure.

The gamble is deciding when to chop.

Sometimes you can pick a spot or two of mold out and get them to finish with very little subsequent mold. Sometimes it all goes to shit in a couple days.

If the forecast is bad and your schedule doesn't accommodate babysitting the plants to squeeze another few days or week out of them, yup, better to chop.

 

[Mrs. Weedstein]

Yea thanks for all the advice. I will plan on chopping sooner than later, but people do successfully grow cannabis in my part of Oregon so I’m not sure it’s quite as precarious as some may believe.

 

[Coloradoclear]

It's all about the genetics and the early finish before the rain . . . Someone throw this man some strains for next year. Lots of folks on here got it dialed in for your area?

 

[Mrs. Weedstein]

What I’m wondering also is how much rain is too much? It’s supposed to rain off and on for the next few days then clear up next week. Is this worrisome or nah?

I use potassium silicate. Agsil 16h goes the farthest. I use it throughout the season so they're beefy come the rainy, cooler weather. I've also heard of and have used milk foliar spray in a 1:3 water solution for pm and possibly other similar issues.

Thanks I’ll see if my grow shop has that.

Your grow shop will sell you something more expensive that doesn't go as far such as rhino skin.

Don't get don't get me wrong, it works but its pricey. I used to use those products but I switch to agsil 16h because it goes so much farther.

LOL, yeah I’m aware grow shop guys do seem to recommend the priciest options... that’s just business, tho

Agsil/silica will not prevent budrot. You def shouldnt be spraying it on your flowers.

Then I would go with 1 : 3 milk water spray on the flowers. That's IF you have a problem. And yes I would avoid silica during flowering.

 

[Mrs. Weedstein]

Should I avoid spraying copper due to taste/health issues?

I would avoid copper and most things. Prevention is best. I had problems last year in Michigan. If you have cooler temps, a lot of rain and high humidity you're at high risk so prevention is really the best thing you can do especially if you don't want to put up plastic or tarps. I've known people that use fans and shake them off as you mentioned.

 

[Mrs. Weedstein]

Yea I try to be preventative but Oregon is pretty conducive to fungus. I know myclobutanil turns into like cyanide when heated but I’m assuming it’s OK to use on a mother plant with some recurrent powdery mildew? I keep her well ventilated but still see tiny little spots of white fuzz every now and then.
