About Master Kush Feminized

We have run Master Kush across multiple environments now, and what stands out is the consistency. Whether in a 3x3 tent under LED or a 4x4 with HPS, this indica delivers a linalool-forward flower at 21% THC that matches the genetic promise. The 89/11 profile shows in how the plant structures itself, bushy, compact, eager to fill lateral space. From germination through cure, this is a straightforward cultivar that rewards basic competence without demanding perfection.

What Growers Typically Observe With This Strain

The vegetative phase is unremarkable in the best possible way, steady, consistent growth with no drama in published cultivation reports. After topping at node 4, plants commonly bush out aggressively and fill a 3x3 space by week 5 of veg. The stretch after flipping is minimal, typically a 25-30% height increase.

Flowering completes in 9-11 weeks. Trichome development typically accelerates in weeks 5-6, and the linalool aroma becomes unmistakable by week 7. Typical indoor yield: 300-400g/mΒ² under LED. Height at harvest: Medium (3-4 ft). Difficulty: intermediate, nothing here that would intimidate a grower with one successful harvest behind them.

The one thing to watch: lower branches that do not receive adequate light produce airy, underdeveloped larf, aggressive lollipopping in week 2 of flower redirects that energy to the top colas.

What Users Report

Master Kush at 21% THC produces relaxed, sleepy, happy sensations that users consistently describe as physically comforting without being immobilizing at moderate doses. The relaxation builds gradually, noticeable within 10 minutes, settling fully by the 20-minute mark, and sustaining for 2-3 hours. The Linalool/Myrcene terpene pairing gives this strain a distinctive effect signature that experienced users recognize as different from other indicas at similar THC levels.

Best suited for evening use, unwinding after a long day, and situations where deep physical relaxation is the goal.

Terpene Profile

Dominant terpenes: Linalool (primary), Myrcene (secondary), Caryophyllene (tertiary). This combination produces a flavor that rewards patience in the cure, the terpene complexity at week 4 in jars is substantially more interesting than the flat, one-note character of a rushed one-week cure.

Who Should Grow Master Kush

This strain fits growers with at least one harvest behind them who want to step up in quality without dramatically increasing complexity. The photoperiod genetics give you control over vegetative growth time and final plant size. Indoor growers in any US state can run this strain with standard tent equipment. Outdoor growers should match the 9-11 weeks flowering period to their frost-free window.

Breeding Goal

Restabilize a late-1990s legacy cultivar to modern uniformity standards.
