diatomaceous earth cannabis

Diatomaceous Earth is really cheap and is an excellent natural treatment and preventative for many pests that plague our plants. It will kill any pests that crawl out of the soil by cutting them up and dehydrating them until they die. You can apply it anytime during plant growth by putting a thin layer atop the soil. It does eventually wash down into the soil which doesn’t do any harm but you will have to reapply periodically. You can apply it directly to the plants as well if you have some kind of an infestation, but make sure you wash it off before harvest. It is actually safe to ingest, so no worries.

Sorry for the long winded post I still can’t get over seeing BD’s grow in person and then seeing it decimated in pics.

You can make a duster by drilling a few holes in the top of a soda bottle and then putting the DE inside so you can puff it out. You can sprinkle it on by hand too. You can buy a duster if you are doing a large area or covering a plant outside.
Anyway, I hope this helps!

This video gives an idea how to make an applicator.
DE will kill spider mites, fungus gnats, slugs, fleas, spiders, and almost any bug it gets onto. You can apply it to your pet to get rid of fleas too.

Great post @GreenLady. I watched the video and I saw that Broad mites were mentioned. @blackdog had an infestation of Russet mites and I believe they are the same or related to Broad mites depending on where you are in the country when I was doing some reading on this awhile back. I think there are identification issues as to what the difference is in the species. Anyway what we have out here are Russet mites that have become a problem in Vineyards and have spread to neighboring cannabis farms. This is near the coastal area of California. Blackdog is in the central valley in the agricultural belt and I read a UC Davis article about mites in the area. From what I gleaned these mites are so small they are an airborne pest so DE wouldn’t be an effective preventive as a soil top dressing.

I’m not posting a problem today, but a solution and preventative.

Diatomaceous earth cannabis

For most any grow, it’s important to try to keep everything as clean as possible. Doing this not only helps prevent pests and pathogens, but also protects your precious buds from being covered in fibers and dust.

When it comes to growing cannabis, everyone strives to provide the best soil to grow the best plants—but there’s always a way to make it even better. Making the soil a better medium is called soil conditioning, which is exactly what diatomaceous earth does. It works by improving the retention of moisture in your potting soil, holding a large amount of fluid and drying at a rate that’s much slower. This natural soil additive also helps to retain nutrients and allows for better oxygenation of the substrate.
Because spider mites flourish in stagnant air, it’s important to ensure proper airflow throughout the entire grow-op. Lots of fresh air going in and out will not only prevent spider mites but fungi and other pathogens as well.

There are many invaders that can ruin your harvest and turn a fun experience into a total nightmare when growing cannabis. Spider mites are by far some of the worst, as they can be extremely hard to get rid of. Employing pest-management protocol helps minimise the risk of an infestation, but may call for the use of harmful synthetic pesticides. Although these help eradicate the invaders themselves, the chemical remnants can be toxic to humans and other animals alike. Luckily, diatomaceous earth is one great natural option that cannabis cultivators can count on to combat spider mites and other critters.
As said before, spider mites are a big problem for growers, thriving more in some environments than others. Fortunately, the conditions in which your plants grow happily are not that great for their arch enemy.
DE is an all-natural, safe-to-use substance that doesn’t harm the cannabis plant with toxic chemicals. The nature of diatomaceous earth makes it useful against most types of insect infestation you might be experiencing; and unlike chemical insecticides, insects can’t develop a resistance to the effects of DE. So once they’re gone, they’re gone for good. DE is an abrasive. and when used as an insecticide, it gradually scrapes away an insect’s exoskeleton, absorbs the fluids, and dehydrates insects and other critters to eventual death.
In a nutshell, DE comes from the fossilised remains of small marine organisms called diatoms. Over a 30 million year period, these hard-shelled algae collected on the bottom of bodies of water, eventually forming into a type of sedimentary rock. Fast forwarding, it wasn’t until around 1836 that a German peasant Peter Kasten discovered the ivory-coloured, powdery substance while drilling a well in northern Germany. Ever since, the usefulness of DE for multiple purposes, including industrial and horticultural applications, has been well-reported. Just sprinkle some diatomaceous earth on top of your soil and watch mother nature’s secret weapon work its magic.
Many things can go wrong during the cannabis growing process, but growers using diatomaceous earth can rest assured that their bud will make it through. Simply put, diatomaceous earth is bad news for bugs.

Hot, dry weather is a spider mite’s cup of tea, so maintaining proper temperature and relative humidity levels is an absolute must.

Highly effective for cannabis cultivation, diatomaceous earth is known to support cannabis plants and kill tiny critters as an all-natural insecticide.
