Genetic Profile
The reported background of Master Kush Ultra places it in a indica lane with clear seed-bank relevance.
For growers, the important question is how those genetics may translate into flower density, stretch behavior, terpene depth, and harvest timing once environment and phenotype enter the picture.
Potency and CBD Balance
Master Kush Ultra is generally listed around 22%–26% THC with below 1% CBD. That range gives shoppers a useful strength marker while leaving room for phenotype, harvest timing, curing, and testing variation.
Potency reads best alongside terpene balance and flower maturity, because two cultivars with similar THC numbers can feel very different in real use.
Sensory Profile
A sharp, spicy earthiness balanced by a bright, citrus-forward finish.
Live flower, late-flower resin, and properly cured buds can each reveal different layers, so growers often watch terpene development closely as harvest approaches.
Terpene Profile
| Terpene | Grower & Enthusiast Notes |
|---|---|
| Myrcene | Often adds earthy, herbal, musky, and body-heavy aromatic depth. |
| Caryophyllene | Can bring a peppered edge that sharpens kush, gas, or earthy profiles. |
| Pinene | Often supports a fresher, sharper nose with classic pine influence. |
