Thanks Shawn, I remember that Lim mentioned this to someone, maybe even suggested it to you or another member to rid of pests. I am almost sure that it will work specially if it is done for more than 4 hours.
However what got me curious is the book I recently read that said that plants actually use O2 and explell Co2 just like all other living things... etc. etc. very new to me!
TTFN
