Description
Bred by Happy Valley Genetics, Sweet 16 Feminised is the result of pairing Ethos Cookies #16, known as The Krux, with End Game #3. The union produces an indica-dominant plant carrying 25 percent THC or above, with an aromatic profile that weaves together floral softness, ripe fruit, and a clean resinous pine note. Effects sit on the heavier end of the spectrum, delivering a grounding, deeply relaxing experience that suits evening use.
In cultivation, Sweet 16 is a feminised photoperiod variety that rewards growers who give it room to perform. Indoor yields push well above 600 g per square metre, placing it firmly in the top tier for productivity and making it a strong candidate for a well-dialled tent or dedicated grow room. Flowering runs 8 to 10 weeks, a manageable window that suits both nine-week schedules and growers who prefer a little extra finish time for peak trichome development. The indica lineage suggests a compact, branchy structure suited to canopy training. For cultivators chasing both volume and quality in a single feminised line, Sweet 16 is a considered, high-return choice.

FAQ
All you need to know
about this product
Sweet 16 brings together Ethos Cookies #16 and End Game #3 in a high-THC indica built for intermediate growers ready to harvest something exceptional.
Sweet 16 sits firmly on the heavier end of the spectrum, producing a grounding, deeply relaxing body experience that pairs well with evening wind-downs. With THC testing at 25 percent or above, this is not a subtle cultivar — expect genuine sedation that eases you toward sleep.
Indoor grows can push well above 600 g per square metre, placing Sweet 16 in the very high yield category for a feminised photoperiod plant. Giving plants adequate space and dialling in your environment will help you hit those upper numbers consistently.
The aromatic profile layers floral softness with ripe, fruity sweetness before a clean resinous pine note comes through on the exhale. It's a nuanced combination that reflects its Ethos Cookies #16 heritage and makes the cured flower genuinely enjoyable to work with.
Happy Valley Genetics rates it as easy to moderate, making it a solid step up for intermediate growers who are comfortable managing a photoperiod plant but haven't yet tackled ultra-high-THC genetics. It rewards attentive care without demanding the precision that more temperamental strains require.
