Dr Who by SubCool
1 other breeder's version of Dr Who — compare flowering times side by side →
Dr Who is a brilliant nod to the golden era of Subcool and TGA Genetics, originally bred in the Pacific Northwest by the crew at Homegrown Natural Wonders. It's a gorgeous 60/40 indica-dominant cross of Mad Scientist and Timewreck. This strain is a perfect example of what happens when you combine heavy resin producers with high-energy terpene profiles. The aroma is incredibly complex, hitting your nose with an overwhelming blast of sweet grape candy and tropical fruit salad, but grounded by a sharp, earthy citrus finish that lingers in the room.
In the garden, Dr Who is a resilient, fast-finishing workhorse that usually wraps up right around the 60-day mark. She throws four distinct phenotypes, but all of them are absolute frost monsters that naturally take on deep violet and purple colorations toward the end of flower, regardless of temperature drops. Growers absolutely love this plant because it shows an incredible natural resistance to powdery mildew, which is a lifesaver in humid basements or damp outdoor climates. You've gotta support those branches, though, because the colas get so chunky and dense they’ll snap themselves right in half.
The high is where the 'time-traveling' name really makes sense. It delivers this wildly uplifting, clear-headed euphoria right out of the gate, making you feel completely engaged and creative. But give it an hour, and that Mad Scientist lineage creeps in, washing a deep, comfortable body relaxation over your muscles that melts away aches and joint pain. With Subcool's tragic passing and the loss of so many mother plants in the California fires, finding authentic Dr Who genetics has become a real treasure hunt on forums. Anyone still keeping this clone alive is doing God's work for the medical cannabis community.

Growing Dr Who: what to expect
As an indica-leaning plant, expect a modest stretch after the flip (roughly 50–100%) and dense bud structure — which makes late-flower humidity discipline the main risk: keep RH in the 40s once buds fatten to stay ahead of mold. Growers familiar with MadS or Timewreck will recognize much of its behavior. Whatever the listing says, the cut in YOUR tent is the ground truth: log feedings, readings, and photos, and let the trends — not the label — drive decisions.
