How to Germinate Lyly Sour x Blue OG Seeds
A healthy harvest starts at germination. The paper towel method is hard to beat: fold the Lyly Sour x Blue OG seeds inside two damp sheets, slide them between two plates, and keep them somewhere dark at 70 to 79°F. A taproot usually appears in two to five days.
Once the taproot is a few millimeters long, move each seed root-down about 1 cm deep into a small pot of light, airy medium. Keep it lightly moist rather than soaked, hold humidity around 65 to 70%, and give soft light while the first true leaves open. Because it is a photoperiod plant, you have the full veg window to build a strong root system before you flip it.
Starter tips
- Use plain, lightly pH-balanced water (pH 5.5 to 6.5) for the first week.
- Keep seedlings warm and humid, but never waterlogged.
- Hold off on nutrients until the second set of serrated leaves appears.
Growing Lyly Sour x Blue OG in the Vegetative Stage
As a photoperiod plant, you control the veg stage with the light schedule. Keep Lyly Sour x Blue OG on 18 hours of light a day for as long as you want it to grow, aim for day temperatures of 68 to 79°F, and hold humidity around 50 to 60%. As a 60% sativa it tends to stretch and reach, growing up to about 1.5 m and often taller outdoors.
This is the stage to shape the plant and set up that big harvest. Topping early and using low-stress training to spread the branches opens up the canopy, tames the sativa stretch, and lifts the yield further. The more even and well-lit the canopy, the more this award winner rewards you at harvest.
Its vigorous sativa frame and October finish make it especially strong outdoors:
- Southern California and the Southwest: the long, warm season lets it reach its full size and push toward that 35 oz-per-plant ceiling.
- Mediterranean-style climates: warm, dry falls suit its October harvest and keep the big colas clean as they finish.
- Large outdoor plots: given root room and sun, it is a true yield monster, so give each plant space to spread.
Flowering and Buds of Lyly Sour x Blue OG
Indoors, flip Lyly Sour x Blue OG to a 12/12 light cycle to trigger flowering, which runs 8 to 10 weeks. Outdoors it ripens through October. As a sativa-led plant it stretches well after the flip, then fills out long, resinous colas, especially rewarding outdoors where it can reach its full size.
Through bloom, drop humidity to 40 to 45% and keep air moving so the big flowers stay clean. The buds build a rich berry and diesel aroma over an earthy, sweet base, the layered signature of its Lyly Sour and Blue OG parents.
At 15 to 17% THC it sits in the medium range, giving a happy, relaxed and talkative effect that stays bright and sociable rather than heavy.
Common Problems and Pro Tips
Lyly Sour x Blue OG is beginner-friendly, but its sativa stretch and heavy yield point to a few things worth watching.
- Manage the stretch: as a sativa it reaches, so top early and use low-stress training to keep an even, well-lit canopy.
- Support the big colas: its heavy outdoor yield means branches can bend late in flower, so stake or net them before they strain.
- Watch the smell: its berry-diesel nose gets loud in flower, so run a carbon filter indoors if odor is a concern.
Expert tip: this one is built to go big outdoors. Give it a large container or open ground, plenty of sun and an early structure of topping plus LST, and this award winner will pay you back with some of the heaviest colas in the garden.
Aroma, Flavor and Effects
The nose is bold and layered: a ripe berry sweetness up front, a pungent diesel bite underneath, and an earthy base that grounds the whole thing. It leans rich and complex rather than one-note, and the fruit comes forward as the buds cure.
The flavor follows the nose, sweet berry and diesel over an earthy finish. On the effect side it is happy, relaxed and talkative, a bright, sociable feel that suits daytime and shared sessions. Because THC runs a moderate 15 to 17%, it stays enjoyable without tipping into heavy.
Dominant terpenes
Lyly Sour x Blue OG carries a deep, complex terpene profile. The most influential are Limonene, Linalool, Terpinolene, Nerolidol, Citral and Eugenol: Limonene brings a bright citrus lift, Linalool a soft floral note, Terpinolene a fresh, complex edge, Nerolidol a woody-floral depth, Citral a sweet, lemony accent, and Eugenol a warm, clove-like spice. Behind them sits a broad supporting cast, including Cedrene, Terpineol, Borneol, Camphene, Fenchol and Phytol, which rounds out its berry-and-diesel character.
Nutrient Schedule
Treat the figures below as a starting map, not a rulebook. Lyly Sour x Blue OG is a hungry, high-yielding plant, so read it closely: tip burn means back off, while pale, slow growth means it wants a little more. All values use EC.
| Stage | EC |
|---|---|
| Seedling | 0.4–0.6 |
| Growth | 0.8–1.2 |
| Early flower | 1.2–1.4 |
| Full flower | 1.4–1.6 |
| Flush | 0.0–0.4 |
Keep the pH around 6.0 to 6.5 in soil and 5.5 to 6.0 in hydro so the roots can actually take up what you feed.
What to Do With Your Trim: Extracts and Hash
Lyly Sour x Blue OG builds a heavy coat of resin and a big harvest, so its trim is genuinely worth keeping. The sugar leaves you take off while manicuring are loaded with trichomes and suit Ice Water Hash, where cold water and agitation separate the resin heads into a clean, solventless concentrate. Pressing that hash into rosin keeps the berry-diesel flavor intact, or you can run a solvent extraction if that is your setup. The bare stems will not extract, but chopped and composted they feed organic matter back into the soil for your next grow.
Harvesting, Drying and Curing Lyly Sour x Blue OG
Timing the harvest comes down to the trichomes. Grab a loupe and watch the heads turn from clear to milky white; a scattering of amber signals peak ripeness. Indoors this lands 8 to 10 weeks after the flip, and outdoors the plants are ready through October.
After the cut, hang the branches in a dark room at 59 to 68°F with humidity near 50% and gentle air movement. Slow beats fast: drying over 10 to 14 days protects the berry, diesel, earthy and sweet aromas that define this strain. When the small stems snap instead of bending, move the buds into jars.
Cure in sealed glass, opening the jars daily for the first week to let moisture escape, then easing off as the aroma deepens. Two to four weeks of patience here is where the ripe berry and pungent diesel really come forward, and it is the step most first-time growers rush.
