Just noticed the activity on this thread . . .
I have not been able to pinpoint the cause of the off gassing but after six months of fresh air I am about to switch back to sealed with an intermittent purge fan going.
I don't think purge fans are normally necessary in sealed rooms; my last sealed room ran for five years without any problems; I think Jackmayoffer runs completely sealed rooms with no purge. But every room is different and maybe sometimes it is necessary?
Co2 is present at roughly 380 ppms or .038% of the atmosphere; 78% is nitrogen 22% oxygen . . . I don't think going from 380 to even 2000 ppms of CO2 would cause there to be a lack of oxygen . . . I don't think that is the problem.

The room is made up of RMAX 1 in ch insualtion board with foam backing. Running 6 k Gavitas in a 15x18x12 room. Like the original post says I am an experienced gardener and my nutes, runoff, ph and temps are on point. I have scoped as hard as I can for root bugs and bugs on leaf with a 40x and no luck. I wish I could find bugs, then atleast I would know what my issue is. I can se the MG deff, but I keep adding mag and nothing happens.@Daggy Can you tell me more about the materials you used. Have you checked the roots to make sure it isn't an infestation of RA or FG?
The thing is couldnt it be a combination of many gasses? I heard wood offgass formaldehyde for month. I also used spray foam. I can look into this because they look cheap.@Daggy Radon tested
yesIs this your first run in this room? First time running gavitas?
Did you use pressure treated? Glue behind the panels? Is this in a basement? Have you grown in this basement before? You pics were invalid.
