When to use each kit type

Short-term kits

Use these for a quick decision point, home purchase timing, or your first baseline result. They are low-cost and easy to deploy.

Long-term kits

Use these when short-term results are borderline, after mitigation to confirm seasonal stability, or when you want a more representative average.
