Diatomaceous Earth: Yay or Nay?

Diatomaceous earth is usually applied as a layer on top of the soil, for fungus gnats and the like. I used the powdered stuff and it mixed with the water to form a weird paste, so dont use that, use granules or whatever other form it comes in

I actually use it in my soil mix (1tbsp/ga of pot). It is a good source of silica, which helps strengthen the plants tissue/cell structure, It also makes it more resistant to disease and environmental conditions (heat/frost/dehydration)
So 1 tablespoon of D. Earth per gallon of soil (or soilless mix) is OK? I mean, it will not interfere with the plant's roots at all? Could you exaggerate a bit more my friend?:D

I was just about on my way to buy some DE. Still going but it's Neem Oil instead.
I don't think you want to inhale tiny silicas....soil ya....but not on my plants.......MIW
Thanks for mentioning that tid-bit. Hadn't ran that through my thoughts yet.
Yeah, that stuff is tiny little bits, that are little razors. Probably not really good on tissue.

You WANT the powdered form of diatomaceous because it's the food grade type, all-natural and safe for plants. The coarse stuff wouldn't kill a pest unless it ate it, where as the powdered can physically cut into their bodies and either kill them quickly or slowly. Most of the course diatomaceous is for pools, and is heated much higher during processing and is much more dangerous to plants and humans, especially if you grind that type into a fine powder. And the best thing to do for getting as much as you can of the leafs is use a dust can, the same you use to spray out your pc, just barely pull the trigger and get off as much as you can. Just use a air mask or bandana so no powder gets into your lungs.
The powdered stuff is what you want.

This stuff is used in food friend, and it's fed to animals we eat. It is harmless unless it is inhaled in powder form in quantity, which is the type you SHOULD be using. Water renders diatomaceous useless when it comes to harming humans, so unless you're using it in your last day of flower which is silly, or you don't plan on watering your plants for the duration of your grow which is impossible, there is NO DANGER in using this product of nature. It does ZERO damage to marijuana at every stage, whether it be a seed in soil, a tiny seedling just sprouting, a 12" vegged plant or a mid flowering plant, which is the latest stage one should use it above soil, it will not hurt it or you. As a matter of FACT, it HELPS your plant and soil by protecting it from disease and other ills, it's great to use if you over-water, and it's actually a useable substitute or addition to perlite.
Facts first, assumptions never.

Another thing I was wondering about last night was since DE is basically 80% silica could someone use powdered silica the same way they use DE? IF so would I be able to just spread a nice thin layer of silica on the top of my soil to get rid of the soil mites?

Chunk their are way to many of them at this point that I feel uncomfortable in my garden.
Go with Spinosad then...............
Get Captain Jack's Deadbug Brew (Spinosad) because it's undiluted therefore more effective than pre-mixed products.
I forget to add Spinosad to discussions about biopesticides not because they don't work but because I don't have to venture out much of the neem and karanja deal so it slips my mind.
Spinosad is extremely effective. Our dog gets an oral version of Spinosad (Comfortis) at the beginning of each month to prevent fleas. She started Spetember 2010 and has not had a single flea or tick. Pretty amazing colony of bacteria.

The Capt Jack sell $40/qt
I need some
DE and neem have helped my dogs; but I think I need some spinosad.
These systemic mites are bad on a weak dog.
