Areto Research estimateNot published by the breeder. Areto Research estimated this with AI-assisted review of the strain’s name, reported parentage and commonly described traits; it is not a source, a lab result or a prediction for any product. Details marked “general guess” have low confidence. Each estimate is replaced as soon as a breeder publishes that detail.
Source access date not recorded. Fields without supporting records remain unknown. Potency and terpene composition vary by product batch; use that batch’s COA for tested values. View sources.
Indica, sativa and hybrid are retail shopping labels, not genetics. Parentage is breeder-reported and not DNA-verified. Use your product’s batch COA for tested potency. How Areto sources this page.
