where you get that badass digital temp/humidity meter? i want one like that... *points*

I, too, am a first time grower.  I recently ordered this thing.  I was thinking of doing something similar as another person with the perlite, air exchange combo.  I was hoping this would work out okay.

I hooked this up yesterday and im not having much luck.  I used a combo of the classic perlite method and this thing and it humidity is staying at 90%

I was reading up on this air exchanger... many of the reviews I've read say that it'll only get to 50-60% humidity...  I am a first-time grower, so I know little about it.  If I get this thing, is it going to be worth it?

not at all dude..its 100% SAFE. u need excellent air exchange to prevent contams on ur cakes..its not too much because it gives  more than enough humidty for ur babies..as u can see on the last pic

I was lookin at the same humidifier/ air exchanger. Im a first time grower do you think that it provides too much air exchange or is it good for the constant fresh air?
