Plague of the White Fuzz
by Soma
As an avid breeder, grower, and one of the most enthusiastic smokers on this Planet, I must say that powdery mildew is one of my worst enemies.
I have finally vanquished the dreaded powdery mildew fungus.
There are many methods, sulphur, milk and colloidal silver to name a few.
They all help but not as good as something that I grew up with as a kid. Good old hydrogen peroxide. Mixing it and water in a good gar-den sprayer is my weapon of choice these days.
What I did was get 30% hydrogen peroxide. I diluted it 3 parts water to 1 part peroxide. What I had then is about a 7-½ % solution, which I then sprayed on my plants underneath the leaves and on top including all of the stems and stalks. Immediately I could see the powdery mildew bubbling away and dissolving. This stuff is so strong that to see it disappearing right before my eyes was so pleasing.
When you are mixing this stuff up and applying it, I recommend wearing protective gloves and avoiding getting it on your skin, in your eyes or on your clothes, in fact wear old work clothes when you do it. I use a 5-liter pump-up sprayer to spray the plants down. I have noticed when the peroxide drops down on the soil it fizzles and makes a mist, but I have noticed no ill effects from this.
What I have noticed is, no more harmful insects. They split without any poisonous chemicals. The harmful insects like spider mites do not like it at all. The best time to do this is just as the plant starts to flower, it can be done later on as well but it needs some recovery time as the parts of the plant that had the mildew die-off leaving healthy new growth free from the dreaded white fuzz.
Being the smoker that I am, loving cannabis with all my heart and soul, I help many coffee shops quality control their wares. They call me up, make an appointment and I come and taste test they’re best and like a famous wine taster, tell them my opinion, which they value highly.
When I spot the remnants of a crop that had powdery mildew it is very disheartening as it basically ruins the taste and much of the high.
Another good way to use the peroxide
is to clean up an infested grow-room before planting a new crop. Make the same
7½ % solution and spray down the ceiling, walls and floors of the tent and let
it dry overnight with the exhaust fans on. You will then have an insect free
grow space.
I have seen many growers spend much time and money trying to cure this mildew; this working remedy is cheap and easy to use.
With the terrible weather we had here in Amsterdam this summer, almost every outdoor grower I know had a problem with powdery mildew.
I spread this remedy around to everyone I know. Try it out and get back to me with your findings so we can all learn more. Love and Light
