About Dr. Who Auto
The most common mistake growers make with Dr. Who is treating it like a simple "set and forget" cultivar. While ${name} is forgiving, the ${indica}/${sativa} balance means it responds noticeably to feeding adjustments at the veg-to-flower transition. Growers who continue veg-ratio nutrients into early flower miss 10-15% of this strain's yield potential by not switching to bloom feed when the first pistils appear. At 20% THC with caryophyllene-dominant terpenes, the quality ceiling is high, but you have to manage the specific characteristics of this cultivar to reach it.
Growing This Strain: Where Things Go Right and Wrong
The three most common issues growers report with Dr. Who:
1. Nutrient timing at the flip. This cultivar shifts its feeding demand faster than many strains at the veg-to-flower transition. Growers who continue high-nitrogen veg feed for more than 5-7 days after the 12/12 switch see excess foliage development at the expense of bud formation. Switch to bloom nutrients within the first week of seeing pistils.
**2. Training timing. Topping too late or too early both cost yield. The sweet spot: top at the 4th node when the 5th is just emerging. This gives you 4-6 strong laterals that develop into even colas. Earlier topping produces weaker branches. Later topping wastes veg time.
3. Harvest timing. With caryophyllene as the dominant terpene, the aromatic peak does not align perfectly with the trichome maturity peak. Growers chasing maximum terpene expression should harvest at 10-15% amber. Growers prioritizing potency should wait for 15-20% amber. These are different windows, know which one you are targeting.
Flowering: 8-10 weeks. Yield: 400-500g/mΒ² indoor / 400-600g/plant outdoor. Height: Short-Medium (2-3.5 ft). Difficulty: intermediate.
Effects and Use
At 20% THC, Dr. Who delivers euphoric, relaxed, uplifted effects with a caryophyllene-influenced character. The onset is balanced, head and body arrive together and remain proportional throughout a 2-3 hour duration. This makes the strain adaptable to different situations depending on dose. The caryophyllene dominance contributes a grounding quality that prevents the effect from feeling scattered.
Terpene Profile
Dominant terpenes: Caryophyllene (primary), Limonene (secondary), Myrcene (tertiary). This combination produces a nose that develops complexity through the cure, expect the primary caryophyllene character to emerge first, with limonene and myrcene notes adding layers over 3-4 weeks in jars.
Who Should Grow Dr. Who
Best suited for growers who value speed and simplicity, autoflowering genetics mean no light schedule changes, compact plants, and harvest in 10-12 weeks from seed. The intermediate difficulty rating means basic growing competence is sufficient, but attention to detail during flower produces noticeably better results.
