Lostintheflood, did you ever try the DIY air conditioner? And if so, did it work out for you?this is a great idea for us, i think. we live in nw washington and i'm a little concerned that we are going to have a very warm summer. normally, we don't need ac, but i'd like to be prepared. typically, we only have a few days of really hot temps..."really hot" means anything over 85!...lol.
maybe this would work really well with dry ice and that would add co2 and no moisture to the flowers...
