CO2 to Kill Mites???

I ran across an old Ask Ed article that suggested that you could kill mites with 10,000ppm CO2 for 15 minutes, and eggs with a second dose 5 days later. Do you think that 5 hours of 2500ppm (during darkness) would have the same or a similar effect? Or is 2500ppm not a high enough concentration to effectively suffocate the life sucking critters. I grow organic and refuse to use chemicals, but I'm looking for a way to regularly maintain the mite popluation (as a complete mite-free room has evaded me for years) or the amount of damage they are able to do during the plants life cycle. If I was to get a CO2 cylinder, how would I be able to regulate 10,000ppm for 15 minutes? Anyone ever tried using CO2 to control mites? Thanks

 

The only way to BE SURE of the ppm's is with at atmospheric ppm meter and they cost $500.

There is probably a estimate you could get by using a certain type of tank & regulator/emitter, factoring in the cubic feet of your growspace.

Prevention is the key to being mite free.
Mites don't travel very far on their own. Indoors, they almost always get in by you bringing them in.
Introducing an infested plant is the #1 way they get in. Another way is to hitch hike on you/your clothes after you've brushed up against or handled infested plants.
Once they're in, you need a major overhaul to completely rid yourself of them. After harvest break down everything & wash it in bleach/water, vacuum the room completely and wipe down the walls since mite eggs are tiny and can hide anywhere.
Put linolium on the floor AND THEN put in a bathtub-style tarp (covers the floor and extends 8" or so up the walls) and keep it clean.
Whenever you bring a plant into your grow area, keep it away from other plants. Put sticky tape around the base of each plant and make sure the leaves don't overlap.
And use a preventitive like a light spraying every 10 days with a pyrethoium/neem oil based insecticide. I use a homemade garlic/soap & hot pepper spray every 10 days.
