GrandDaddy Purp (Subway Scientist) by Aphria (Riff)

Welcome everyone, we’re looking at GrandDaddy Purp today. This offering is by Aphria, they sell it through their brand called Riff. They’ve chosen to call it Subway Scientist, but we don’t make fun of names here on

Aphria’s GDP is one of the first offerings I reviewed on this website, I tried one of their pre-rolls. Go back and check it out, and take note, my review style has changed quite a bit since then.

Let’s first orient with GrandDaddy Purp. The lineage isn’t confirmed, but generally known to be either a cross of Purple Urkle and Big Bud, or a Mendo Purp with a Big Bud. Initially popularized in California, the cultivar has attractive elements for both consumers and producers. Typically, the buds have friendly fruit tastes, and show expensive colours, which is appealing to consumers. For producers, the cultivar has the reputation for providing massive yields. And so, GDP has risen to immense popularity, probably on that simple, self-propagating mechanism; people like consuming it, and growers like growing it.

Now, GrandDaddy Purp was created by Ken Estes. We have more of his work available in the market, it’s over at Tweed (Ken’s Kush, Candyland). Let’s just stay on this point for a moment. It’s like someone bred a new version of arugula that lead to a famous sandwich, which Subway sells. And the person that made the arugula isn’t even involved with Subway, in fact, they’ve since started making new sandwiches for Panera Bread. Which one do you go for? And, how does your answer change when considering ethics, or awareness? Most people know Grand Daddy Purp, but my suspicion is that Ken’s Kush may not be on everyone’s radar.

Anyways, that’s just my round about way of saying some people can grow good, and some can breed good. And, if you like good things, best to be aware of who is actually making that stuff. Not sure if we’ll find either here.

Back to Aphria’s Subway Scientist. Their description prompts us to ‘mellow out‘ with this indica ‘strain’ and its ‘purple hue‘ with ‘bright and juicy‘ berry.

This is a THC dominant offering, content ranges 10% from 15% to 25% THC (CBD makes up <1%). What arrived to me had 19.75% THC, so a hair under the range average.

Dominant terpenes for GDP are listed as Caryophyllene (59.2%), myrcene (31.6%) and limonene (13.6%). There are no ‘other’ terpenes listed for this offering. Also, the relative terpene amounts add to 104.4%, but don’t judge, could be subway math, it’s dark down there.

Aprhia grew this one in a greenhouse over in Leamington Ontario. They packaged it up March 18 2019, sent it to Alberta Cannabis, where it was purchased by little old me for this review, 106 days later.

Visuals on the GDP buds I received are a mix of good and bad. The purple hues promised in the description come through, even on the smaller buds I received. Looks great up close, despite the poor trim job.

Tactually, the buds are fragile. Moisture content is low, the buds have no malleability, a slight force would crumble them.

Grinds to a dust but still maintains the nice purple hue throughout. The dryness will present difficultly for use. I am going to vaporize this, but at a lower temperature. If I had to smoke it, I’d roll it as long and slim as possible (for good vaporization through the cylinder). Applying fire directly to something with this consistency, like in a bong or pipe, would likely be a waste.

Check the video of the grinds, I had a hard time finding premature seed growth to zoom into. They’re well above my idea of standard. Whether it’s attributable to the grow or the cultivar itself, they look great.

I use a Volcano vaporizer, which has a mesh filter at the bottom of the loading chamber. After loading the chamber and moving it to the unit, I see there is a collection of trichomes that has fallen through the filter. Not something I see often.

Scents are fairly benign but the sweet berry note is detectable. A good amount of smokey earths round out the bottom of the profile. Not as described, I wouldn’t call it juicy, the dryness causes it to suffer.

Tastes are light. I perceive the convex of slightly skunked berry over the smooth earthy myrcene. There’s structure here, but it’s only static, the tastes don’t flow or change. GrandDaddy Purp has memorable character, this version leaves much to the imagination.

Pronunciation is disappointing, and longevity is short. Vapour production was light overall, but still enough for multiple cycles.

Price on this single gram was $10.33. The low moisture content led to disappointing olfactory content, the character was there, but in low amplitude. This could be a widespread problem, or could be related to my specific package. Either way, there are a few valuable features to this listing, it has above average cannabinoid content and below average price. Regardless of my experience here, I’d still recommend you be aware of it and do your own due diligence, if you encounter it.

At the time of writing (data current June 2019), Aprhia has been reliably below the average in most markets they operate in, which I expect to continue.

The other note I wanted to mention is Aphria usually duplicates whole flower offerings across two brands. For example, they sell Rockstar as Riff Blue 98 and Solei Unplug. Aphria’s GrandDaddy Purp doesn’t have a duplicate offering, for now, you can only get it as Subway Scientist.

Anyways, GrandDaddy Purp, the stats are good enough to keep on your radar. I’d love to see a good rendition of this legendary cultivar, at the competitive price Aprhia brings. They just need to figure out how to get the quality right, based on what I saw here, I’m not sure they’ve got it yet.

Thanks for reading, see you on the next one.
