Positronics Seeds: 12 Feminized Strains Built For Flavour

Twelve Positronics strains sit on this shelf, all feminized, eight photoperiod and four autoflowering. One myth to kill straight away: neither Supercheese nor Supercheese Auto has a published CBD figure, so the 0.3% you keep seeing next to "super cheese" belongs to Black Widow, Jack Diesel Auto and Afghan Auto. What you do get here is Somango 47 at 18% THC, Blue Rhino at 1.9% CBD, and a breeder that chases taste before anything else.

What Positronics Seeds Actually Put On The Label

Let's finish off that first point, because it's the thing people get wrong most often. There is no cannabinoid figure recorded for Supercheese or Supercheese Auto in our catalogue, and we're not about to borrow one from another strain to fill the gap. If a CBD number is what you're shopping on, three Positronics strains have one on record.

The CBD Numbers That Are Actually On Record

Black Widow runs 19% THC with 0.3% CBD and finishes in 55-66 days. Jack Diesel Auto matches that 0.3% CBD next to 19% THC, going from seed to harvest in 65-75 days. Afghan Auto also carries 0.3% CBD. Blue Rhino is the odd one out at 1.9% CBD, well up on its Blueberry and White Rhino parents, and there's a CBD+ Critical 47 on the shelf as well.

Flavour First, With Cups To Show For It

Taste comes before yield in this part of our cannabis seeds range. Caramelice's seeds won at the 2010 Spanish Champions Cup, and Super Cheese, the parent behind Supercheese Auto, carries two Spannabis Cup medals. Mellow Jelly is the one to know if you like a house project: it's a Positronics x Zamnesia Seeds collaboration, not a solo release from either side.

The Beast, The Berry And The Spider

Somango 47 crosses Somango with Critical #47, nicknamed The Beast, 18% THC, 82-90 days of flowering and 400-500 g/m2 indoors. The aroma is dark fruity liquor with a burnt, earthy undertone, and the smoke is thick enough to feel like velvet on the way down. Blue Rhino tastes of spicy wood and berry, stays short, and gives up to 600 g/m2 indoors or around 500 g per plant outdoors after eight to nine weeks. Black Widow is floral with a menthol aftertaste, about a metre tall indoors for 400 g/m2, or 1.5-2 m outdoors with roughly 300 g per plant in early October.

Photoperiod Or Auto, Pick Your Timeline

On the photoperiod side you've got Somango 47, Blue Rhino, Black Widow, Supercheese, Jack Diesel, Caramelice, CBD+ Critical 47 and Mellow Jelly. The autos are Jack Diesel Auto, Supercheese Auto, Afghan Auto and Northern Haze Auto. Supercheese Auto is done in about 65 days at 350-400 g/m2 indoors, 500 g per plant outside, and for that old-school skunky cheese we'd take it over Greenhouse Exodus Cheese Auto every time.

Humidity Down, Smell Contained

Somango 47's problem is its own success: the buds get so dense and the foliage so thick that trapped moisture turns into mould if you don't keep humidity under control. Jack Diesel Auto turns pungent as it matures, so run a carbon filter unless you fancy the whole stairwell knowing. Supercheese Auto is worse, it will stink out a fair patch around the grow space near the end. First Positronics grow? Our seed team would start you on Supercheese Auto, no light timer to babysit, then move to Somango 47 once you've got a hygrometer and the habit of reading it.

Frequently asked questions

Does Supercheese have 0.3% CBD?

No. There's no CBD figure recorded for Supercheese or Supercheese Auto, so we won't quote one. The Positronics strains with a documented 0.3% CBD are Black Widow, Jack Diesel Auto and Afghan Auto, while Blue Rhino sits much higher at 1.9%.

What is Somango 47 crossed from?

Somango 47 is Somango crossed with Critical #47, an indica-dominant hybrid nicknamed The Beast. It carries 18% THC, flowers in roughly 82-90 days and gives 400-500 g/m2 indoors. It grows compact with several strong branches holding up big flowers.

Which Positronics strain is easiest for a first grow?

Supercheese Auto, since it flowers on its own clock and is ready in around 65 days. Jack Diesel Auto is also easy going and still gives about 120 g per plant. Just plan for the smell on both, they get loud towards the end.

Have any Positronics strains won awards?

Yes, two we can point at. Caramelice's seeds won at the 2010 Spanish Champions Cup, and Super Cheese, the parent of Supercheese Auto, holds two Spannabis Cup medals. That cheese lineage is the reason the auto version tastes the way it does.

Which Positronics seeds give the biggest indoor yield?

Blue Rhino, at up to 600 g/m2 indoors while staying around a metre of headroom. Somango 47 follows at 400-500 g/m2, and Supercheese Auto sits at 350-400 g/m2. Give Blue Rhino's root system room to spread and plenty of light.
