indoor greenhouse in my office

[estación seca]

The Dens and Neos don't need such high humidity, and it greatly increases the risk of fungal diseases. Aim for 60%-70% maximum. As you've discovered Phals really like high humidity, but fungal and bacterial rots are a big risk. You need fans in your tanks. Aim for 70%-80% maximum with the Phals. They won't grow as fast as at 90%-100% but you won't walk in one day to a bacterial rot attack. If your tanks are ever cooler than you would like drop the humidity to the ambient in the room by removing the covers. This will prevent water condensing on cold plants, which can become a fungal disaster.
