Grow facts
Grow facts come from the breeder first, then seed banks and strain databases. With 2 sources we show the range and the middle; with 3 or more, the range and the median, after leaving out values far from the rest. The breeder's own value is the anchor, unless it is far from every other source (outside their range and more than 20% from their median); then we show the full range and the median of all of them. A fact from a single source is marked "1 source", and a fact no source lists is left out. Yields are converted to one unit: indoor per square meter, outdoor per plant.
CTU writes every profile from these facts; we do not copy other sites' descriptions. Values that are a generic default in the source data are left out. Last checked Oct 21, 2026.

Ghost OG is a hybrid derived from OG Kush and Joe's OG Kush with reported THC levels that vary widely between phenotypes, prized for its dense colas and potent balanced effects. This strain appeals to growers seeking a resilient plant with moderate height and a flowering time of 8 to 9 weeks. Its strong citrus aroma and high resin production distinguish it among Kush varieties. It thrives both indoors and outdoors, particularly in warm, dry climates.
The high onset of Ghost OG starts with a cerebral uplift that transitions to a relaxing body calm, maintaining balance without heavy sleepiness. Effects typically last 2 to 3 hours, with a peak around 45 minutes. Harvesting at the right window helps balance energetic and body effects, making it suitable for evening use without excessive drowsiness.
On opening the jar, Ghost OG presents a sharp citrus aroma with pine undertones. The inhale offers a diesel and earthy flavor profile, followed by a pine-fresh exhale. Proper curing enhances its citrus brightness and smooths the diesel edge, preserving terpene complexity.
Ghost OG grows well both indoors and outdoors, showing moderate plant height and dense bud formation. Indoors, it benefits from training methods like topping and SCROG to manage its moderate stretch and enhance light penetration. Outdoors, it performs best in warm, dry climates with stable humidity below 50% during late flowering to prevent mold. Its high resin production requires careful airflow management, especially in dense colas. Nutrient sensitivity suggests a slow EC ramp starting around 0.8, while temperatures should be kept between 70-80 deg F to avoid terpene degradation. Yield optimization depends on canopy management and early training to prevent uneven growth.
Ghost OG's moderate stretch and strong training response mean that topping and SCROG early in flowering are critical to avoid uneven canopies and maximize light penetration. Its dense, resinous buds require vigilant airflow and humidity control to prevent mold, especially in indoor grows where humidity can spike.
Indoor growers using topping or SCROG will appreciate Ghost OG's strong training response and dense structure for maximized yields. Growers in dry, warm climates will benefit from its outdoor resilience and mold resistance. Those focused on extract quality will find its very high resin production advantageous, while intermediate growers seeking manageable stretch and moderate nutrient needs will also find it suitable.
Compared to OG Kush, Ghost OG has a slightly faster flowering time and higher resin production, enhancing extract potential. Against Ghost Train Haze, it offers a more balanced relaxing effect rather than the energetic haze high. Banana Kush shares Kush lineage but typically has sweeter flavors and a more sleepy body effect, while Ghost OG balances uplift and body calm.
Reported THC levels for Ghost OG vary widely between phenotypes, growers and labs, so we don't list a single figure. If you're buying it, check the lab-tested THC on the product label.
Ghost OG is a hybrid strain derived primarily from OG Kush genetics, which are indica-dominant. It combines both indica and sativa traits to produce a balanced effect that affects both mind and body.
The flowering time for Ghost OG ranges between 8 to 9 weeks indoors. Outdoor growers can expect harvest readiness by early to mid-October in northern climates, requiring attention to environmental conditions for optimal bud development.
Ghost OG is moderately challenging to grow, making it suitable for intermediate growers. It responds well to training methods like topping and SCROG, and its moderate stretch helps manage plant height, but it requires careful humidity and airflow control to prevent mold in dense buds.
Ghost OG features a complex flavor profile with sharp citrus and pine notes on the inhale, followed by earthy and diesel undertones on the exhale. Proper curing enhances its terpene-driven brightness and smooths the diesel edges, resulting in a rich and balanced taste experience.
