Relentless Powerdy mildew

[Grojak]

I grow outside and I try to select genetics that deal better with molds and pests. Just takes time, years, but you can buy genetics from places like Oregon Green Seeds, that have been breeding outdoors and selecting for PM resistant plants for decades.

I’ve bred strain for the harsh PNW outdoor, last year it was the only one that didn’t mold. If it can survive PNW it’s safe to say it’ll do good anywhere. Funny one of the OGS breeders did work with the same male strain as me, but I think the secrets in my female.

I'm growing several PNW bred strains outdoors here in Oklahoma this year, and our heat and humidity and an outbreak of leaf septoria is threatening most of my plants. Most of my stuff will be harvested early, if at all. Thats outdoor growing for you. Deb at OGS is a very experienced breeder and I have learned a ton just studying her genetics descriptions and she often tells the details of her selection process.

PNW OD plants need to be mold and pest resistant of course but they also need to be fast! The DJ Blueberry mom in my OD strain finishes in 55 days indoors, you need that here. The longest flowering plant I have Od this year is a 63 day indoor but I will be putting all plants under greenhouse fabric before the rain starts.

I’m glad OGS is giving the details, there is no secret formula for selections, all breeders should offer that info. What PNW strains are you growing?

I have grown OGS's Maxwell's Silver Hammer, a 56 day sativa dominant hybrid that really did finish fast, mid Sept. here for me. I also grew OGS's Sugar Cookies, OGOG, Oaxacan Iranian, (A crowd favorite, also finished mid Sept) . All grown outdoors. I also grew OGS's Double Diesel indoors and it was perhaps the strongest strain I have personally grown. Many of these are not in stock at the moment, but descriptions can still be found on line. This year I have a couple of crosses made by Dutch Blooms, who grows outdoors in far north Washington state. One is a Chem 4 cross and the other is Alaskan Thunder Fuck x Sodo. I also have Coke a Cola x Root Beer Freeze from Dutch Blooms and it began flowering June 20th and didn't reveg, should be done by early Sept.

"Porch misting system" + Drum fans + Zerotol 2.0 used as directed. Set a 1/2 horsepower pump on a 12 hour timer, spray plants every 12 hours followed by running those drum fans ideally tunneling air through canopies while sprayers go off to distribute the mist into the canopies. To hold spray line up you can simply buy some channeled fence posts and connect them using bolts to get them high enough then ziptie the spray lines to them..

100 ft porch misting system or 50 ft depending on your needs, a couple drum fans to move air on wet days or stagnant days, make sure your drum fan is a sealed motor meant for outdoor use then some zerotol. You could probably get away with just zerotol if you have decent airflow in your area, also the zerotol is Hydrogen Peroxide (h2o2) with Peroxyacetic Acid (PAA), the PAA stabilizes the oxygen molecule in the h2o2 so that it doesn't evaporate as quickly as if it were pure h2o2. This allows longer surface contact before it breaks off and turns back into oxygen and water.

Using h2o2+PAA will help prevent mold, mildew, most bugs, good and bad unfortunately (any exoskeleton bugs will get dried out)



If you can't afford a setup like that, your kinda boned, cause that defeats the purpose of outdoor growing imo. At that point, you might as well grow indoors to avoid smoking and inhaling mildew.

Great to hear someone else uses Zerotol! Game changer in my outdoor grow!

Yeah it's good stuff I only grow indoors but it works wonders for cleaning plants without leaving residue. I learned a couple years ago it also works on soft bodied insects, it will put the fatal smackdown to thrips/aphids if they are properly soaked using a fogger. I've cleared infestations using it then following up with something like Lost Coast Plant Therapy (extremely overpriced) BUT works really good as an IPM and smells like peppermint. Just note that plant therapy leaves a shitty coating on everything. I have quit using it for that reason and exclusively use ZeroTol for issues. As for walls and floors I use a 3% bleach water solution to nuke any surface contaminants, dead or alive.

Glad you mentioned Lost Coast Plant Therapy. I inherited a gallon of it but I don't want a residue left on my plants, in flower. I don't worry about insects outdoors, there are always some, but nothing overwhelming, in my experience.

So I've treated my plants 3 times. Twice with milk 1 time with baking soda. It keeps sneaking back. Any suggestions for treatment that may help.

I've been growing our favorite plant outside for about 50 years now. Powdery Mildew is a given in southern California. High PH water once a week will keep it well under control and is the best choice for Organic production as it is.... Wait for it...... Water.

1 tablespoon of Potassium Bicarbonate or Sodium Bicarbonate (baking soda) to 1 gallon of water. Drench spray once a week. No chemicals. No residue. No health risks. This raises the water PH to about 9 and is enough to disrupt the cells of the PM but not high enough to harm the plant.

It is more than past time to start weekly spraying of BT Thuricide for caterpillars. Start that Aug 1st.
