Milk for powdery mildew

[Mastajay]

Outdoor grow, 2 days after Using lactose free 2% milk 1 definitely slowed, if not stopped the spread. Killed most that was present. This leaf was not well coated and is the worst one on the whole plant. Any other spots I see seem
To be in sparsely coated areas. Going to re spray sparsely coated areas and report back!

Thanks Mastajay! I look forward to seeing how it goes.

I'd cover the leaves to dripping, tops and undersides, to make sure it's a solid experiment.

Yeah you're right! Just don't want to get the buds full of rotting milk.

Bud wash! Almost everyone here does . No one should be smoking buds with castille soap spray, BT, spinosad, or Bacillus amyloliquefaciens on them. Not to mention dust, bugs, bug poop, or PM.

I wash with 50/50 H2O2/water because it kills the bugs and gets rid of the PM as well. Some folks use baking soda and lemon juice. Either way, it's a good idea to wash your harvest at chop indoors or out.

 

[Mastajay]

So H2O2 is hydrogen peroxide right? How often do you specifically wash buds?

 

[InTheShed]

As soon as I cut the plant down. Branches come down and get swished around a bucket (without touching the sides or bottom) filled with hydrogen peroxide and water. I put them on a wicker table to drip dry while I do the rest, then spray them gently with a hose to rinse them off. Some folks use two additional buckets of water for rinsing but I'm outside so the hose is easier for me.

Then they get shaken out and hung on a line in the shade for 4 or 5 hours, the fans get stripped, the buds get trimmed, and they get hung inside to dry for as close to a week as I can get.

Some folks dry trim but I prefer to wet trim. That way I can find any rot or caterpillars before any more damage gets done.

 

[Mastajay]

Sounds like quite the procedure!

Wash rinse trim dry burp cure. Easy peasy.

Update! Yesterday's pm infested leaf is looking good! At certain angles you can faintly see some remnants. Now to see if it comes back!

 

[InTheShed]

So the milk doesn’t leave any residue after spraying? Nice!

 

[Mastajay]

It does, but it's clear.

And shiny .

Hey Shed - what are your recipes for these mixtures - I like this idea!! Thanx

 

[Mastajay]

Just had to post this. Just cause

Love those flowers! I can see why you felt the need to post .

Here is a link to a great Lemon Juice/Baking Soda wash tutorial from Dutchman. I just go with a bucket of water 50/50 with H2O2 and a hose to rinse. Same principal all round though. Swish, rinse, drip dry.

2 days after milk. Slight remnants of pm. Still not sure if it's a live or dead. Been 4 days since first spraying of whole plant. No new pm on the rest of the plant. Definitely seems to stop the spred.

Bud wash seems like a good idea. Any links on hom to make a drying box?

PM leaf day 2

Looks good! Depends on how complicated you want the drying box to be. Some folks make them with computer fans and screened vents, I just used string and vent holes. Give me a minute and I'll find a pic...
