Sealed room: problem with buds smell pls help!

[Gkkush]

Hello everyone,
New here, looks like I found the right place

Ive been growing for several years and lately moved to a new house where i set up my old setup.

Unfortunately, ive been having issues ever since.
The weight of the crop is lower than what I usually get with the same genetics abd setup (around 550
Grams per meter, under 480w quantum leds and a co2 tank enrichment, 50l per 24h dehumidifier).

But worst than that, the buds come out with a fungy smell after being dried and cured. Smells like there is almost no terpene production or like botrytis (although no visual signs of botrytis)

I imagine this has to do with the air circulation in the room. I keep the room sealed at all times, levels of humidity are well - 45-50% and tampature is around 29-32°. Co2 ppm is 1000-1200ppm.

Im terrified that my next cycle will also be ruined.

Any suggestions or guidance regarding the air flow in the grow room using fans, blowers in any specific directions maybe?

Any tip will be helpfull.
Thanks a lot

Yes it is all old stale carbon from a can and recirculated air conditioner smell without any fresh air. Maximum energy consumption pending math with temp and humidity outside of grow room. Fans on timers with 12 hr light during night (off peak) instead of day will change power consumption. Legal means fans no hiding to me, your setup may vary. I don't have a sealed room, aphids or spiders ate any mites except maybe inside some powder mildew and moths keep attacking

32c normal? I find that inline with charts, that it's the ruin temperature. Especially with such a low RH. I'm talking about the voc's of interest just vapourising.

If you can't find the funky smell, the filter (as mentioned) is a good starting point, and the de-hu's evaporator, which should have a pre-filter to clean. You could spend $20 on some dip slides and check your tank and substrate to. Any drains. You get 10 tests. It's an eBay/Amazon item, or you can get fancy about specific substance slides. It's a future move for me, I'm yet to try them, but almost excited to do so
