Crystal Seeds

Northern Lights Power Meets White Widow Precision

Crystal seeds deliver a hard-hitting 60/40 indica-dominant hybrid with up to 25% THC, bred from two of the most legendary strains in cannabis history — Northern Lights and White Widow. Available as feminized seeds from Homegrown Cannabis Co, ILGM, and High Supplies, and as autoflower seeds from Weed Seed Shop and MNSL, Crystal is one of the more accessible high-THC seeds on the market for growers who want serious potency without a steep learning curve. If you're looking for a reliable, resinous strain with commercial-grade yields and beginner-friendly genetics, Crystal seeds consistently deliver.

Crystal Feminized vs. Autoflower Seeds

Seed TypeFlowering TimeYieldBest For
Feminized8–9 weeks400–500g/m² indoors / 750g/plant outdoorsMaximizing yield, outdoor grows, controlled indoor setups
Autoflower8–10 weeks from seed300–400g/m² indoorsFaster turnaround, discreet grows, multiple annual cycles

When to Choose Feminized

Feminized seeds are the right call if yield volume is your primary goal. Crystal's feminized version produces up to 750g per plant outdoors — figures that make it one of the stronger high-yield seeds in the indica-dominant category. Growers running dedicated indoor seeds setups with full environmental control will also appreciate the 400–500g/m² ceiling. The 8–9 week flowering window is competitive for a strain at this potency level, and the Northern Lights x White Widow lineage is well-stabilized across breeders like Homegrown Cannabis Co and ILGM, meaning phenotype consistency is generally reliable.

When to Choose Autoflower

Crystal autoflower seeds from Weed Seed Shop and MNSL suit growers who prioritize speed and flexibility over maximum yield. At 8–10 weeks from seed to harvest, the auto version is only marginally faster than the feminized — but the key advantage is light-schedule independence, which matters for outdoor seeds grows in shorter seasons or for growers running multiple cycles per year. Expect slightly lower yields compared to the photoperiod version, but the same Crystal genetics and resin profile remain intact.

Buying Guide: Crystal Seeds

Where to Buy Crystal Seeds and What Each Seedbank Offers

Crystal seeds are currently available from six seedbanks, with feminized seeds carried by Homegrown Cannabis Co, ILGM, High Supplies, MNSL, and Weed Seed Shop, while autoflower seeds are stocked by Weed Seed Shop and MNSL — making those two the only options if you want the auto version. Homegrown Cannabis Co and ILGM are the most established names on this list and typically offer Crystal feminized seeds in pack sizes ranging from 4 to 20 seeds, with bulk pricing available at higher quantities. High Supplies tends to be competitively priced on per-seed cost, which is worth checking if you're ordering in volume. If you want to compare autoflower pricing specifically, MNSL and Weed Seed Shop carry different pack configurations, so it's worth checking both before ordering.

Payment, Shipping, and Germination Guarantees

For a strain at Crystal's THC ceiling — up to 25% — genetics verification matters more than it does with lower-potency varieties. ILGM and Homegrown Cannabis Co both offer germination guarantees on their Crystal feminized seeds, which provides a meaningful safety net given that high-THC crosses like Northern Lights x White Widow can occasionally show phenotype variability across seed runs. Most of the seedbanks listed accept cryptocurrency payments with a discount applied, and credit card options are available through Homegrown Cannabis Co and ILGM. Stealth shipping is standard across this list, which is relevant if you're ordering Crystal seeds internationally or to regions with stricter import policies.

Is Crystal Worth the Price?

At its price point, Crystal feminized seeds represent strong value for a beginner-rated strain with a 25% THC ceiling and 750g/plant outdoor potential. Comparable Northern Lights x White Widow crosses — or strains with similar specs — often carry a premium because of the lineage recognition. Crystal sits in a sweet spot: it's not priced as a boutique strain, but the genetics are solid enough that it competes directly with higher-priced indica-dominant high-THC seeds in the same category. If you're deciding between Crystal and a single-lineage strain (pure Northern Lights or pure White Widow), Crystal's hybrid vigor and higher yield figures typically justify the price difference. Buy Crystal seeds when you want the combined resin and yield profile of both parent strains without paying for a limited-edition release.

Crystal Seeds — Frequently Asked Questions

What's the difference between Crystal Feminized and Autoflower seeds?

The feminized version of Crystal flowers in 8–9 weeks and produces up to 750g per plant outdoors, making it the higher-yield option. The autoflower version finishes in 8–10 weeks from seed regardless of light schedule and is available from Weed Seed Shop and MNSL. The core genetics — Northern Lights x White Widow — are the same across both types, but the autoflower format trades some yield ceiling for scheduling flexibility. If yield volume is your priority, go feminized; if you need light-independence or faster outdoor cycles, the auto version is the better buy.

What THC level can I expect from Crystal seeds?

Crystal seeds are rated up to 25% THC, which puts them firmly in the high-potency category. This figure is consistent across the major seedbanks carrying the strain — Homegrown Cannabis Co, ILGM, and High Supplies all list similar potency data. Because THC expression can vary between phenotypes, buying from seedbanks that provide lab-tested or verified genetics (such as ILGM or Homegrown Cannabis Co) gives you better confidence that you're getting seeds selected for that upper THC range. CBD content is negligible, so Crystal is squarely a THC-focused purchase.

Is Crystal a good strain for beginner growers?

Crystal is officially rated as a beginner-difficulty strain, which is notable given its 25% THC potential and high-yield genetics. The Northern Lights x White Widow lineage is well-stabilized and forgiving, which is part of why multiple seedbanks — including High Supplies and MNSL — stock it as an entry-level option. For first-time buyers, the feminized version from Homegrown Cannabis Co or ILGM is a practical starting point, as both offer germination guarantees that protect your investment if seeds fail to pop. The beginner rating applies to both the feminized and autoflower versions.

Where can I buy Crystal seeds online?

You can buy Crystal seeds online from six seedbanks: Homegrown Cannabis Co, ILGM, High Supplies, MNSL, and Weed Seed Shop all carry feminized seeds, while Weed Seed Shop and MNSL are your options for autoflower seeds. For buyers prioritizing germination guarantees and established customer support, Homegrown Cannabis Co and ILGM are the most reliable choices. For competitive per-seed pricing on feminized packs, High Supplies is worth comparing. If you want Crystal autoflower seeds specifically, compare pack sizes and pricing between Weed Seed Shop and MNSL before committing, as configurations differ between the two.
