Before explaining the treatment to fight it, we will know more as it develops:
White powder is a fungus parasite who attacks the aerial parts of the plants.
This fungus grows on the surface (cannot penetrate the leaves), and therefore can be fought with fungicides.

Leaves are covered (typically by its axial portion) with a layer of white powder, similar to the talc. The fungus initially manifests in isolated plants, and can cover the entire crop later.
Optimal conditions for powdery mildew appears often hated themselves of Spring.
Its propagation is optimal between 25/28 ° C, reaching its development stop temperatures above 35 º C, and being lethal to the fungus temperatures above 40 ° C.

As it is spread by wind, in indoor growing is a dangerous enemy, as they usually have some fans often emulate the wind in the rapidly growing area and can spread to other plants.
As says the Spanish adage , "prevention is better than cure", the best and the most effective weapon against powdery mildew is prevention.

To do so, cleaning spotlight before planting, avoid waterlogging in irrigation, and cleaning with bleach and water in the area of culture is essential to prevent mildew.

Many growers use sulfur as a preventative, I must say that you can leave certain knowledge in the grass, and also that at temperatures below 18 ° C does not work, and that with a temperature above 35 ° C can burn plants.

For preventive is recommended propolis in growing phase, once sprayed, and other foliar on day 10 after spraying.
It is also advisable to place a small cloth filter on the air intake to prevent both entry and all kinds of dirt.
Highly recommended also using an ozonizer, it prevents against fungal attack, because they have antibacterial qualities, microbicides and sterilants, and itâ??s help to mitigate the smell of plants.


I couldnâ??t prevent it, what can I do?:

The favorable conditions for propagation are:
High humidity, low temperature, bad air, low light levels, plants crowded together, that prevent good air circulation between them.

If you've found the fungus ... try to keep humidity below 50%, as this will cost spread to powdery mildew, this helps to control its spread while you're trying to get rid of the mildew.

If you can, try turning off the ventilation, as the air from the fans make the wind necessary for propagation of our culture.
You have to keep in mind that plants may show early signs (whitish stains, similar to talcum powder) a few weeks after infestation.
If the state is not very advanced, the first thing we suggest is VERY discard infected leaves (not recoverable and will avoid its spread).

The second is to remove the affected plant rest of indoor growing, to prevent its spread to other plants.

If powdery mildew is not very advanced, we can use home remedies like baking soda: Mixing two spoons with one liter of water, add a little potassium soap and sprayed onto the foliage wetting the whole plant.

If the fungus is advanced, and yet our marijuana plant is still in its growth phase or early weeks of flowering, the important thing is to act quickly and eradicate the outbreak, since as we have noted, the mildew spreads with astonishing rapidity. Systemic fungicides like Penzocanol, Cyproconazole, pyrifenox are very effective.
The market offers products against powdery mildew as: Fungicide Dino Greendel Gree 35, Combo or Bayleton Meltatox Bayer CA. Chemicals are not advisable, but to combat this fungus, whenever we are in growth or early weeks of flowering is the most effective way.


Hope this info will be useful for everyone!
Enjoy Friday :)
