Modified Mints (GMO x SinMint Cookies) crosses GMO to SinMint Cookies: Garlic Cookies - Chemdog put over the Forum Cookies cut against the Forum Cookies cross that made Sin City's name nationally. Neither is a filler parent, which is why this pairing is worth a pack rather than a look. Sin City have been running these house parents for over a decade. The value in a cross like this is as much in the known half as in the new one.
GMO sits on the seed side here, SinMint Cookies on the pollen side. If you have seen these two names paired the other way round, that is a different pack and not this one.
Genetic Lineage
- Mother: GMO. Garlic Cookies - Chemdog put over the Forum Cookies cut. Parentage: given as Chemdog, often the Chem D cut, crossed to Girl Scout Cookies Forum cut. Credited to Mamiko Seeds, though a breeder called skunkmasterflex is also named as having found the pheno. Mamiko called it GMO; dispensaries were wary of putting those three letters on a shelf and relabelled it Garlic Cookies, which is why the same plant has two names.
- Father: SinMint Cookies. SMC - Cookies over Blue Power, and the strain most people meet them through. Given as given as Girl Scout Cookies, Forum cut, crossed to Blue Power. Bred in the early 2010s, and it is the cross that took Sin City from a Las Vegas name to a national one.
- What to expect across a pack. Two distinct parents means real variation in frame, finish and nose. Select early and take cuttings off anything you would want again.
Flavor and Aroma Profile
The nose is where these two argue hardest.
- The Aroma. Savoury rather than sweet - garlic and onion over the Chem fuel, which is where the nickname came from from the GMO side, against dough and mint with a kush floor from the SinMint Cookies side.
- The Taste. Garlic and fuel with the Cookies sweetness well behind it up front, turning to dough, mint and kush together through the exhale.
Where the parents disagree
- Two different harvest dates. Long for an indica - ten to eleven weeks, or seventy to seventy-seven days for GMO, sixty to sixty-five days, yielding three to five hundred grams a square metre for SinMint Cookies. Judge each plant on trichomes rather than pulling the room together.
- The smell is a negotiation. Savoury rather than sweet - garlic and onion over the chem fuel, which is where the nickname came from on one side against cookie dough with mint over a kush base on the other. Neither wins outright in every seedling.
- Two frames in one pack. GMO is indica-dominant on paper but it stretches like a sativa through early flower, then stacks dense spear-shaped colas under thick wet resin. SinMint Cookies is about sixty forty indica, with dense compact buds under trichome coverage heavy enough that they read almost white at harvest. Decide which suits your room before you flip, because you get both.
Cultivation and Growth Traits
- Plant Structure. The two parents disagree here, so plan for range. GMO is indica-dominant on paper but it stretches like a sativa through early flower, then stacks dense spear-shaped colas under thick wet resin. SinMint Cookies is compact and dense, and it finishes so frosted the buds read pale.
- Vegetative Phase and Training. Open the middle out early. Light reaching the lower sites is worth more than any late correction.
- Flowering Time. The parents are not on the same clock. GMO runs long for an indica - ten to eleven weeks, or seventy to seventy-seven days, SinMint Cookies sixty to sixty-five days, yielding three to five hundred grams a square metre. Judge each plant on trichomes rather than pulling the room together.
Effects and Experience
- The Mind. Growers describe GMO as heavy.
- The Body. Reported in line with that. This is not a plant described as pulling in two directions.
In the pack
Seeds from Sin City Seeds. The house style is a modern flavour plant crossed onto a stable Sin City male, which is why their releases hold together better than most crosses chasing the same trends. Original Sin City Seeds stock.
