Mold is a living organism and, therefore, has conditions needed to support that life. So before committing to the time, money, and effort to build a greenhouse-enclosed home, I researched the potential for mold in the home. Once I knew what conditions mold needed to grow, I could try to find ways to maintain the home’s environment in such a way that it did not support mold growth. I figured this couldn’t be an impossible task because even in the perpetually damp Pacific Northwest I’ve never had a mold issue in any home of my previous 60 years.
Before construction I documented the plan in this post: But What About Mold? Now that I’ve been living in the home for 4 months, this is the start of what will be a periodically recurring update on any signs of mold. Although I will be looking all over the house and greenhouse throughout the month, the following are the most likely places for mold to first appear so I will provide the monthly update on the locations in the table below.
During the month, the average temperature and relative humidity:
| Location | Ave Temp | Relative Humidity |
| Kitchen | 65 F 18.3 C | 42-50% |
| Greenhouse | 44 F 6.7 C | 58-100% |
Current Conditions
| Shower | No visible sign of mold |
| Toilet | No visible sign of mold |
| Laundry | No visible sign of mold |
| Kitchen Sink | No visible sign of mold |
| Metal Siding at West Pool | No visible sign of mold |
| Metal Siding at South Potting Bench | No visible sign of mold |
| Cedar Siding at East Pond | No visible sign of mold |
