New Laboratory Results: 12 month analysis on storage
The following report is based on a sample stored over a ~12 month period. Storage conditions were in a glass container, humidity controlled via a Boveda pack, humidity monitored using a Sensorpush, room temperature, low/intermittent light. Temperature averaged 65.8F with a maximum of 82F and a minimum of 54.4F. Relative humidity average 65.8% with a maximum of 68.5% and a minimum of 64.5% after stabilization.

The original sample vs this long-term storage sample shows minimal differences in THC content. Results are subject to statistical sample size error and testing variation.
The green color has certainly changed and the tricomes appear more golden in color. We see a significant conversion of about 50% of the THCa into THC. About 1.6% decrease in CBG having perhaps been converted to THC or CBC. Total cannabinoids remain approximately equivalent while there was a slight increase in the max THC (perhaps as a result from the CBG conversion).
With that noted, this result is a surprise to me. I would have expected to have seen a significant overall decrease in the THC compounds overall. But, it appears possible that the relatively large amount of CBGa in the original sample has decomposed into compounds that have offset any loss of THC by degradation. While about 50% of the existing THCa converted to THC.
This result in no way should be taken as gospel. The sample size is too small and non-homogeneous. But, it may be interesting enough for further study.
See the OP for the original reports on this particular strain (#4). *Terpene analysis is in progress and will update report when completed.

Very interesting results on the terpene analysis. Significant change in the overall profile. The amount of terpenes decreased as expected but it also appears that some of the terpenes that were detected originally have decomposed into different terpenes. I’ll need to research this a bit to understand what is going on here.
