With the addition of ruderalis genes, these feminized autoflowering seeds ensure a no-nonsense, ultra-quick harvest. They're not dependent on the light schedule, either.
Want to know why Critical Purple autoflower seeds are a must for any beginner grower, veteran stoner, or part-time partaker?

What are Critical Purple autoflower cannabis seeds?

Critical Purple autoflower seeds are the product of crossing the original Critical Purple strain with a ruderalis phenotype. The male chromosomes were then removed, resulting in the Critical Purple auto-flowering feminized cannabis seeds you’ll find at the Homegrown Cannabis Co.
These top-shelf beans have been genetically engineered to:
- Produce female-only plants for guaranteed nugs.- Grow quicker from seed to harvest than their photoperiod counterparts.- Automatically flower after a set period, regardless of the light schedule.
Critical Purple autoflowering plants are also naturally pest-resistant and can withstand colder climates, so they’re versatile and perfect for novice growers. When exposed to chilly conditions, their foliage becomes purple-tinged.
Their indica traits are evident in their structure—short and bushy with broad leaves and lateral branches. They only reach a height of about two to four feet tall, ideal for confined spaces indoors and out.
Don’t let this hybrid’s small stature fool you, though. Famously dense and heavy, their buds are loaded with THC in the 20%–25% region. They’re usually dark green with violet hues and burnt orange pistils. 
Towards the end of the flowering stage, a thick covering of frosty trichomes signals that harvest time is near. You won’t have to wait too long because Critical Purple autoflower seeds grow notoriously fast. 
With their ruderalis genes, they enter the flowering stage on their own. They don’t need uninterrupted periods of darkness like feminized seeds or regular marijuana seeds.This genetic hack means you can germinate and grow Critical Purple autoflower seeds all year long. The result? A continuous supply of sticky bud.

What are the Critical Purple autoflower effects?

As a high-THC indica-dominant hybrid, Critical Purple autoflower is a hard-hitter. Still, it takes some time before it fully kicks in. From the outset, a gentle cerebral buzz massages your mind, releasing those metaphorical knots of worry. A sense of tranquility sets in, lifting your spirits as stress bounces off and away into the ether.
At this point, you may experience elevated mental clarity, paving the way for Critical Purple’s indica traits to manifest. Some time passes before a hearty warmth washes over your body, enveloping you in a cocoon of comfort. 
A slight tingling sensation isn’t uncommon as relaxation reaches your limbs. They become heavy, and before long, settling down into a cozy spot is irresistible. Physical activity is put on the backburner as Critical Purple auto’s sedative effects grow stronger. The profound body high intensifies until you’re left basking in blissful contentment. 
A spot of the munchies may kick in, so keep snacks and beverages nearby. Couch-lock is inevitable, and you’ll likely drift off to dreamland to catch some quality Z’s. Because of these sock-knocking effects, it’s best to keep Critical Purple auto for evenings or a quiet weekend, when you can unwind, relax, and rest.
Dry eyes and cottonmouth are common occurrences, so stay hydrated and keep some eye lubricant handy. More adverse reactions like dizziness, headaches, or anxiety could also manifest if you overdo it. Whether you’re a newbie or if you just have a low THC tolerance, it’s best to stick to smaller doses. 

What does Critical Purple autoflower smell like?

Critical Purple autoflower seeds produce buds that smell like a garden filled with flowers and lemon trees after a storm. Sweet floral notes paired with a citrus zing captivate the nose and entice the senses. 
There’s a slightly earthy undertone that’s more herbal than skunky too. Once lit up, blended aromas of wood and damp earth are also present on the exhale. Hints of lime and freshly-dug herbs play on the tongue, accompanying the sweet, smooth smoke.

How to germinate Critical Purple autoflower seeds

While these Critical Purple seeds are of the auto variety, they still need to be carefully germinated. Follow these effortless steps for best results:
- Step 1: Wash your hands and get everything together. You’ll need your cannabis seeds, purified water, sterilized tweezers, a clean dinner plate, and absorbent paper towels.
- Step 2: Use the purified water to wet two paper towels. Don’t overdo it, though. Make sure you remove any excess water.
- Step 3: Carefully place one paper towel onto your dinner plate.
- Step 4: With your sterilized tweezers, gently place your marijuana seeds onto the paper towel. They should be at least an inch apart.
- Step 5: Place the second paper towel over your cannabis seeds. It should still be moist but not sopping wet.
- Step 6: Gently remove the paper towels off the plate to double-check that there’s no accumulated water. If there is, discard it. You don’t want your marijuana seeds to drown.
- Step 7: Cover your dinner plate with another and store it in a warm, dark place. A drawer or cupboard is ideal.
- Step 8: Leave your cannabis seeds there for 24–120 hours. Make sure they’re moist at all times during this stage. If they dry out, they won’t sprout.
- Step 9: Plant your newly sprouted marijuana seeds once they develop a healthy-looking taproot.

Critical Purple autoflower seeds grow guide

Critical Purple autoflower seeds are resilient, versatile, and beginner-friendly. They’re pest- and disease-resistant and flourish in a grow room, tent, greenhouse, or garden. Plus, they can tolerate harsher conditions and will even develop a purple hue as the temperature drops.
Critical Purple autoflower plants take a fraction of the time to become harvest-ready compared to their photoperiod sisters. With a flowering time of 49–56 days or 7–8 weeks, you can easily produce a few harvests a year, regardless of the season.
From seed, these vixens take a total of about 10 weeks to complete their entire life cycle. Some growers wait another two weeks to enhance yield, flavor, and potency, though. As autoflowers, these crops don’t depend on an adjusted light schedule to enter the flowering stage. Instead, they’ll start producing massive buds according to their internal clock.
With their small, compact size and brief life cycle, they don’t require any training. They’ll also do well in both soil and hydroponic growing mediums. Indoors, you can cultivate Critical Purple autoflower crops continuously, harvesting about 14.1 ounces of bud per meter squared. 
Here are a few indoor cultivation tips for optimal results:
- Make sure your plants get at least 18 hours of light a day throughout their life cycle. If you can manage the heat and the costs, you can keep the lights on 24 hours a day for increased growth.
- Keep the temperature range around 71°F–77°F.
- During the early (pre-flowering) stage, keep relative humidity levels between 40%–70%.
- When your Critical Purple autoflower plants start flowering, adjust the relative humidity levels to below 50%, ideally in the 20%–40% range.
- Because they’re short and bushy, your crops need sufficient space to grow and proper air ventilation.
Outdoors, you can germinate two batches of Critical Purple auto-flowering feminized cannabis seeds—one towards the end of March and one in late June. This way, you can harvest in June and again in October. You can expect to yield about 5.2–7 ounces per plant.
Here are a few outdoor cultivation tips:
- Protect your Critical Purple autoflower plants from extreme cold. While they can withstand cooler conditions, the temperature shouldn’t drop below 66°F. The ideal range is around 71°F–77°F.
- Avoid the rainy season. Too much water can be harmful, and your crops might struggle to get enough sunlight.
- Opt for a secure spot protected from harsh elements. Too much heat, cold, wind, or frost can ruin your harvest. 
Whether you opt for an indoor or outdoor grow, keep these tips in mind:
- Once sprouted, it’s best to start your Critical Purple autoflower seeds in their final containers. Due to their quick flowering time, transplanting them can interrupt growth.
- If you’re a beginner, well-aerated, nutrient-rich organic soil is the easiest growing medium. Soilless mixes like perlite, coco cair, or peat moss are also good options for those with a bit of experience.
- Porous containers like fabric pots are best for optimal root development.
- A 3-gallon pot is ideal for your Critical Purple autoflower plant to reach its maximum height.

What are the Critical Purple autoflower strain genetics?

As mentioned, Critical Purple autoflower seeds are the product of crossing a ruderalis cultivar with the original Critical Purple strain. 
The resulting indica-dominant hybrid contains the following genetics:
- Critical Mass: An indica-leaning hybrid known for its medicinal benefits, high THC content, and skunky citrus flavors. It’s the product of two legendary parents: Afghani and Skunk #1.  
- Big Bud: This crowd favorite is a robust indica-dominant hybrid with Afghani and Skunk #1 parents. Some variations include Northern Lights genetics, while others are said to have a Haze influence.
- Ruderalis cultivar: A strain used to incorporate autoflowering qualities without interfering in Critical Purple’s flavor profile or characteristics.
Breeders initially crossed Critical Mass with Big Bud to improve the latter’s yield and genetic stability. Their offspring, Critical Purple, has since become a classic cultivar in its own right. With the autoflowering ruderalis advantage, these marijuana seeds make it possible for growers of any experience level to cultivate Critical Purple.
