Description
Magnetic Marker from G13 Labs is a feminised photoperiod strain built on a foundation of carefully selected genetics. As a photoperiod variety, it moves through vegetative growth on your schedule before transitioning to flower once light cycles shift, giving cultivators precise control over plant size and canopy development. The result is a grow shaped entirely by your timing and intent.
On the cultivation side, the feminised format means every seed is destined to produce a flowering plant, eliminating the guesswork of sexing and making efficient use of your space and resources. As a photoperiod strain, Magnetic Marker suits both indoor setups, where light cycle control is straightforward, and outdoor gardens in climates with a well-defined seasonal shift. Growers who appreciate the ability to extend the vegetative window, train plants, and dial in their environment before committing to flower will find this strain a natural fit. A steady hand and a structured setup are all it takes to see what G13 Labs built into these genetics.

about this product
Magnetic Marker from G13 Labs delivers reliable all-female crops, earthy depth, and a well-rounded indica-sativa high, ready for growers of all levels who want full control over their canopy.
It's genuinely one of the more forgiving places to start with photoperiod growing, rated easy across all experience levels. Because every seed produces a flowering plant, you won't lose time or space to male plants, and the medium height keeps canopy management straightforward. The flexibility to control vegetative length also means beginners can keep things simple while more experienced growers dial in exactly the structure they want.
Indoors, Magnetic Marker typically returns between 350 and 450 grams per square metre under well-managed conditions, which sits comfortably in the average-to-solid range for a feminised hybrid. Per-plant yields run from around 200 to 450 grams depending on how long you allow the vegetative phase to run and how well the environment is dialled in. It's consistent rather than spectacular, which is exactly what most reliable harvests are built on.
The flowering window runs from 8 to 10 weeks once you shift your light cycle to 12/12, which is a fairly standard timeline for an indica-sativa hybrid of this type. That range gives you a little room to observe trichome development and harvest at the point that best suits the effect profile you're after. Earlier pulls tend to lean more uplifting; letting it run toward week ten generally deepens the relaxing qualities.
The flavour profile is grounded in earthy, woody notes — classic, resinous, and unfussy rather than loud or sweet. The effects pair a relaxing body quality with an uplifting mental edge, making it a well-rounded experience that doesn't lean too heavily in either direction. THC sits in the 16–24% range, so potency is meaningful without being overwhelming, and CBD remains low at under 1%.
