OG Kush

Environment

OG Kush generally favors temperatures in the mid-to-upper range comfortable for most indoor grows — roughly the mid-70s°F (low-to-mid 20s°C) during lights-on, with a modest lights-off drop. Humidity is the key lever: keep relative humidity closer to 40–50% in veg and aim to bring it down toward 40–45% or lower as flower progresses, given how densely this strain tends to pack its buds. Good horizontal airflow through the canopy is especially important — stagnant air is a persistent risk factor. VPD awareness helps, but the practical priority is preventing humid microclimates inside dense bud sites.

Training & canopy

OG Kush tends to respond well to topping early in veg, helping redistribute apical dominance and promote lateral branching. LST pairs naturally with topping to open the canopy and improve light penetration to lower nodes. A SCROG net can work well given its moderate, manageable stretch — filling a net evenly is achievable with adequate veg time. Avoid aggressive defoliation late in flower; the plant tends to need some leaf buffer to manage stress in its final weeks.

Flowering

OG Kush typically flowers in roughly 8–9 weeks, though individual phenotypes can vary. Expect a moderate stretch in the first 2–3 weeks of flower — often 50–75% above its pre-flip height — so manage canopy height before the flip accordingly. Bud sites tend to stack and swell noticeably around weeks 5–6, and resin production usually becomes prominent in the final two weeks. Watch trichome development closely toward the end, as the harvest window can be relatively narrow on some phenos.

Difficulty

OG Kush tends to be finicky about climate consistency and is moderately sensitive to overfeeding and humidity swings — less forgiving than a typical beginner strain.
