about this product
Marshmallow OG from Ethos Genetics delivers sour, gassy complexity on OG Kush roots, ready for beginner to intermediate growers who appreciate a properly cured, character-driven harvest.
It sits in the easy-to-moderate range, making it genuinely accessible for growers moving beyond their first grow. The feminised photoperiod format gives you full control over veg time, so you can build the plant up at your own pace before triggering flower. That flexibility is actually a real advantage for anyone still getting comfortable with the process.
Marshmallow OG leads with a sour, gassy character that has real depth, layered with a floral lift and a clean piney finish on the back end. The profile is nuanced rather than one-note, and it genuinely rewards a patient, thorough cure — rushing it would undersell what this cultivar can produce. Growers who take the time to let it fully develop will find the aroma complexity holds up well.
Expect a heavy, relaxing body high that leans firmly into couch-lock territory, consistent with its indica-dominant OG Kush lineage. THC sits in the 16–24% range, so the experience has real weight to it without tipping into extremes. It's the kind of effect profile that suits evening use and genuine unwinding.
Indoors, Marshmallow OG typically comes in at 350–450g/m², with individual plants capable of 200–450g depending on how much veg time you allow. Flowering runs 8 to 10 weeks, which is a fairly standard window for an OG-based photoperiod variety. The six-seed pack gives you enough to run a proper trial and dial in your technique across the phenotype range.
