Pyramid Seeds: Spanish Feminized and Autoflowering Cannabis Seeds

Picture the usual setup: a 100x100 tent, a decent light, and no patience for a four month grow. That single decision, auto or photoperiod, splits this shelf down the middle, and Pyramid Seeds is one of the few breeders where both halves are worth your money. If you're weighing this brand against the rest of our cannabis seeds, here's the honest summary: Pyramid Seeds chase weight and speed first, flavour second. Watermelon Zkittlez proves the flavour side has caught up, but the numbers are still the reason growers keep coming back.

Egyptian Names, Spanish Sun

The expert breeders from Pyramid Seeds work out of Spain, and the catalogue reads like it. Auto Alpujarrena is named after the Alpujarra, the run of valleys on the south flank of the Sierra Nevada, and the whole pitch is first-class Spanish bud. You can see what a long Mediterranean season does in the outdoor figures: Gorila can hit up to 1000 g per plant outside, Purple Urkle and Watermelon Zkittlez both sit in the 750 to 1000 g per plant bracket, all finishing in September. Put those same plants in a wet northern garden and you'll get a fraction of that, so read outdoor numbers as best-case Andalusian sunshine rather than a promise.

Half the range wears an Egyptian mask. Tutankhamon, Ramses, Blue Pyramid, all pharaoh branding on plants bred to stack colas. The other half is straight American genetics reworked in a Spanish grow room: Gorila from Chem Sis crossed with Sour Dubb, Purple Urkle built on Mendocino Purps, Double OG Haze for the couch, and Romulan, which got its name from a Star Trek species because the reddish-purple sugar leaves poking out of the buds genuinely look alien.

The name gets mangled in search boxes more than most. Piramide Seeds, Piramid Seeds, Pyramide Seeds with the German plural e, Pyramid Seeda from a finger sliding off the s, or just Pyramid Seed in the singular. Same Spanish breeder, same shelf, so don't worry if you found this page through a typo.

One thing we won't do is hang cups on the brand. Purple Urkle's Cali side of the family made its name through multiple victories at High Times Cannabis Cups, and a classic like Northern Lights had already won countless awards long before any breeder built on it. That heritage belongs to the strains, not to a trophy cabinet in Spain. Anyone telling you Pyramid Seeds itself has a Cup shelf is filling space.

The Packs We'd Actually Reach For

Two lanes here, and they suit different growers. The autos are for anyone who wants a harvest date they can circle on a calendar before the seed even cracks. The feminized photoperiods are for growers who already know how to top a plant, keep a canopy flat and wait out nine or ten weeks of flowering for the extra weight.

Autos That Finish Before You Lose Interest

Auto Tutankhamon is the one we hand to first-time growers. She runs 110 to 130 cm, spends 20 to 25 days in veg, then 45 to 50 days flowering, and still comes in around 450 g with 20% THC and a softer hit than the numbers suggest. Auto Blue Pyramid is the faster autoflowering version of Blue Pyramid, ready 60 to 67 days from germination, and she can genuinely reach half a kilo at 24% THC with 1.4% CBD and 0.3% CBN alongside. Watch out for her height range though: 40 to 90 cm is a big spread, so you can't plan your light distance precisely until she shows you what she's doing in week three.

Auto Ramses is the Haze option, a last-generation autoflowering phenotype of Amnesia Haze that races from seed to harvest in about 70 days. Average height sits at 70 to 120 cm, though she's capable of stretching to 2 m if you feed her, with up to 450 g/m² indoors and 200 g per plant outdoors. At 16% THC the buzz is clean and awake rather than heavy, and the smell is the best part of the run: orange and lemon up front with dank earth and spice underneath. Give her 18 hours of light from seedling to harvest, or full sun outside. One honest caveat for all three autos: no topping, no revegging, no fixing a bad first fortnight. If a seedling sulks in week one, that's weight you never get back.

Feminized Photoperiods Worth the Extra Weeks

This is what people are looking for when they search fem Pyramid Seeds, and it's the stronger half of the range. Gorila was bred for tolerance breakers, crossing Chem Sis with Sour Dubb to land at 25% THC. Indoors she gives roughly 400 g/m² after 56 to 63 days of flowering, and the small dark green and purple buds smell of pine, wood and lemon with enough resin on them to gum up your scissors within one plant. The stone is a fast body weight that lingers for hours, then brings the munchies with it.

Purple Urkle is the show plant. Built on Mendocino Purps, 80% indica, 20% THC, and colas that turn genuinely purple thanks to high anthocyanin levels, the same pigment behind blueberries and red cabbage. She gives 350 to 400 g/m² indoors after 55 to 60 days, and the terpene mix runs tropical fruit, ripe grapes and skunk. Evening smoke only, unless you like doing nothing.

Romulan is the pick if you value strength over volume, at 75% indica and 24% THC, though be realistic about her indoor return: around 300 g/m² after 50 to 60 days is modest next to Gorila. Outdoors she doubles up to about 500 g per plant. If you're chasing indoor bulk instead, Purple Chem at 700 g/m² is the better bet. Watermelon Zkittlez sits at an exact 50/50 split, made from Watermelon Zum Zum #3 and OG Eddy, giving around 400 g/m² after 60 days of flowering, with a sweet watermelon flavour that comes through properly in a vaporizer and gets lost in a joint. Worth knowing that other breeders cut the same cross differently: Watermelon Zkittlez from Barney's Farm chases maximum weight, while the Pure Instinto version is a small-batch take on the same watermelon genetics. And if you want to sink into the sofa and forget the day, Double OG Haze is the indica-dominant, high-THC one that does that in minutes.

Auto or Fem, and How to Keep the Spare Seeds Alive

Quick way to decide. Pick an auto if you're growing in a small space, sharing a tent with plants at different ages, or want two runs in one season. Auto Tutankhamon and Auto Blue Pyramid both finish in roughly nine to ten weeks from germination and need nothing clever from you. Pick a feminized photoperiod if you can control your dark period, want to veg a plant to fill the tent, and care about the extra 100 g or so per square metre. Gorila and Purple Urkle both reward a proper veg and a flat canopy, and both need 55 to 63 days of flowering before you get near a harvest. Outdoors in southern Europe the photoperiods win by a mile, since September finishers can put on several hundred grams that an auto simply doesn't have the time for.

Seeds arrive in the breeder's own sealed pack with the strain and genetics printed on it, and they travel in plain packaging with nothing on the outside naming what's inside. Popping the whole pack at once is the most common mistake we see. Germinate what fits your space and keep the rest properly:

• Cool, dark and dry. A drawer away from the radiator is fine, the fridge is better.
• Keep them sealed with a silica sachet so humidity swings don't tire them out.
• Skip the freezer. Repeated thawing is what kills viability, not the cold itself.
• Write the date on the pack. Two years on, you'll want to know whether slow germination is the seed or your method.

So, one pack this month. Never grown before, small tent, want a harvest date you can trust: Auto Tutankhamon. Already know how to top a plant and want the strongest smoke on the shelf: Gorila at 25% THC. Growing outdoors in a warm garden with room for one big plant: Purple Urkle, harvested in September, purple colas and all.
