So the ph def wasent it.

i don't think so as half of them were foliar fed for 2 days and it didn't make any difference. it would be nice to know how long to chill before trying to find out what "plan b" is..

[Zandor]

when you have a sealed room you sould exchange the air once a day at the very least.

Well then I guess you don't need the play sand then thought they were roots.

[Timdog]

question- if i have proper temp, humidity, and co2, why exchange air?

[Zandor]

To remove stale air and organic gas build up. You want the plant to be as healthy as possible donâ??t you?

[Timdog]

yes of course i do. what i'm asking is exactly what am i removing from the air? i'm just saying it won't get musty from the dehumidifier, heat isn't an issue, and since i'm adding co2 and the plants put off o2 what exactly am i doing wrong? having it sealed keeps out bugs as well as smell. obviously you've been at this longer than I have but what is it that my air is lacking given my situation? i would apprecaite some experienced input as for what the technical benefit is.

thanks!
