HP 13 S1 Feminized Seeds – Legendary Hash Plant Power for Effortless Relaxation

Ready to Grow a Living Legend?

Ever looked at your grow tent and thought, "Damn, I wish this was easier"? HP 13 S1 feminized seeds are about as close to autopilot as you’ll get while still actually growing weed. CSI Humboldt, those mad scientists of sticky green, cooked up this indica-heavy hybrid so both newbs and old-timers can grow fat, stanky buds with zero drama. HP 13 S1 = deep relaxation, a wave of hashy throwback aroma, and a creative boost when you least expect it. Whether the day’s been a canyon of misery, you want pain relief, or you’re just after an easy win, this strain is your one-way ticket to low-maintenance high grade.

Quick HP 13 S1 Stats

  • Parentage: Hash Plant 13 x Hash Plant 13 (yes, that’s double trouble)
  • THC: 18% to 22%
  • CBD: Less than 1%
  • Indica/Sativa: Indica-dominant hybrid
  • Flower Time: 63 to 70 days
  • Yield: Moderate but mighty
  • Seed Type: Feminized
  • Grow Difficulty: Stoner-proof
  • Best Use: Evening chilling, creative doodling, pain obliteration

HP 13 S1 Genetics and Lineage

  • Mother: Hash Plant 13—think dense, resin-caked colas and hash funk that would make your dealer’s head spin.
  • Father: Hash Plant 13 (selfed)—basically the plant started dating itself for maximum stability and old-school punch.
  • Breeder: CSI Humboldt—masters of West Coast weed wizardry and bulletproof seeds.

HP 13 S1 is about genetic lockdown. No wild surprises. Just resin, more resin, and uniform killer buds. It’s like the Henry Ford of weed: any color you want, as long as it’s gorgeous green and sticky as a mafia bribe.

Strain Breakdown

  • Indica/Sativa Ratio: Heavyweight indica hybrid
  • Hybrid Benefits: Couchlock deluxe with a side order of, “hey, let’s make some art,” if you can find the crayons.

Growing HP 13 S1 Seeds

What It Takes

  • Skill Level: Beginner-magnet. Screw-ups forgiven. Lost interest for a week? Plant won’t care.
  • Indoor Specs:
    • Size: Short, bushy, fits tight corners—good for nosy neighbors
    • Lighting: Photoperiod; just flip the damn lights, you’ll be fine
    • Temps: 70–80°F is the sweet spot. This ain’t rocket science.
    • Nutes: Doesn’t whine—just give it basic food and bloom juice near the end

How She Grows

  • Structure: Chunky monkey—fat stalks, huge fans, dense buds, and did we mention barely any trimming needed? That’s right, lazybones.
  • Flower Time: 63–70 days—about the length of a bad summer job.
  • Trains Easy: Top, bend, scrog—she’ll flex but won’t flop.
  • Pest Resistance: About as tough as they come—bugs, mold, whatever. HP 13 S1 shrugs it off unless you throw her in a swamp.

Yields to Expect

  • Indoor: 350–400g/m²—solid stash, easy win
  • Outdoor: 400–500g/pl—harvest parties encouraged
  • Pro Tip: Slightly spoil her with Cal-Mag and she’ll lay down thick, greasy colas

Climate Game

  • Loves long, mellow summers but won’t throw a fit in less-than-perfect spots. Indica backbone = survivor.
  • Warning: If humidity spikes in late flower, just vent it out and chill.

TIP FOR FRESH SPROUTERS: Never started outdoor cannabis indoors before? Don’t wing it and end up with limp seedlings. Check out our no-BS guide right now: Starting Outdoor Cannabis Seeds Indoors. Your harvest will thank you. So will your sanity.

HP 13 S1 Effects and Experience

Physical

  • Body high that spreads like hot fudge—melts tension, wipes out pain, and yeah, the couch will get its use.
  • Medical types swear by it for crushing aches, stress, and vicious insomnia. THC hits 18–22% but keeps things functional (mostly).
  • Effects rumble on for a couple hours, then let you drift down smooth instead of dropping you off a cliff.

Mental

  • Upbeat, slightly goofy euphoria (the “I love you, man” kind). Good for coloring outside the lines or quality movie marathons.
  • Not pure knockout—save it for after work, but don’t expect to write the Great American Novel after two joints. Enjoy the moment.

Flavor & Aroma

  • Terpenes: Myrcene, Pinene, Caryophyllene, Limonene, Humulene
  • Scent: Old-school hash, pine, and earthy spices—library of dank.
  • Taste: Spicy, hashy, a little woody. Makes your tongue say, “hell yes.”
  • Stink: Heavy-duty. Put a filter on that tent unless your landlord already likes you.

HP 13 S1 Seed Specs

  • Type: Feminized—basically means every bean turns into a bud factory. No dudes to toss.
  • Germ Rate: 90–95% if you can handle a wet paper towel. Seriously, you got this.
  • Looks: Big, striped, mean little beans built to sprout strong.

Packaging & Storage

  • Discrete, ninja-level shipping. Neighbors will never know.
  • Stash ‘em in the fridge in a pill bottle with some rice, and you’re set for years of gardening glory.
  • Fast replacement if your seeds punk out. You grow, we got your back.

  • Derek G.: “Old-school head here—this is like time travel. Smells like the 90s, only better. Greasy, fat nugs and I pulled almost a half pound in a tent. Buy this.”

I just wanted to tell you guys thank you! Got my gear today and I really appreciate that freebie. I was actually looking at that pack so now I can try it first. The stickers are awesome. Your box is amazing. Didn’t know you guys have auctions also I told my dispensary about a year ago to send everyone to you guys. Hopefully they have been because they ask me where people can get seeds and I told them you guys. That was Beyond Hello the goose Lake Road location in Sauget, Illinois. Also, thank you for the pineapple high chew! Love it all! Thank you so much!
