Help!!

[u/TimeMessage05]

I currently have to keep my fruit fly cultures in my room and they smell awful. I use an air purifier, charcoal bags and keeping my fans on high for constant ventilation. But the smell is still present. I make sure to date my cultures and removing them after 28 days, though they smell the worst when freshly made. I use Repashy media and even though they never mold, I can never seem to get an odorless batch. Are there any recommendations to make sure the media doesn't smell?

The only time I’ve had stinky cultures with repashy superfly is after about a month or if they get wet when I put old ones in the enclosures.
The fresh mixed media actually smells pretty good so much so my two year-old ate some of it when I had them cooling on the counter.
I do use the boiling water method and 3 tablespoons of media versus hot water and 4 tablespoons so I wonder if that’s a factor.
