Pest control with CO2

[turtle420]

Found this:::

Okay so the whole 6 years i've been growing all I've had a problem with in any of my hydro or soil systems spider mites are the only problem. this is how you fix it. Okay first off you could just use nem oil. Spray it in the bottom part of the leaves. Or just for 15 minutes take a propane bottle full of Co2 and bleed it into the room on a high table with fans since Co2 is heavier than Oxygen and the fans will help move it around the room. Nothing liveing after 15 minutes in that room won't live. So be careful. But I've done it and when your done look at the leaves an they will still be there but they will be dead and you just need to brush them off the leaves. If there's anymore questions let me know. Contact info on my pro.

and...

Yes there is a point where the plant will close up and OD on CO². It's very high like 4500 PPM or so but I don't know the exact number.

I did the same thing to mine trying to kill spider mites.

So, I'll give it a try.

15 minutes everyday... hmmm...
