Xpie77 Week 1 report – Girl Scout Cookies (Spliff Seeds) 🌱🍪
5 seeds germinated in 0.2-liter pots, under a propagator with LED setup
This week was purely focused on germination and the first seedling stage. The propagator kept the RH high (ideal 65-80%), protected against dry air, and maintained stable temps. The LED provided soft light without heat issues – perfect for delicate seedlings.
General setup details
Propagator: closed or half-open for high humidity, light ventilation from day 5-7
LED: full-spectrum, low intensity (dimmable or low wattage), cycle 18/6 or 20/4
Distance from LED to propagator/plants: 60-90 cm (24-36 inches) – prevents stretch or stress
Temp: 23-26 °C (root zone warm, air slightly cooler)
RH in propagator: 65-80%
Water: pH 6.0-6.4, minimal doses around the stem, substrate moist but not wet
Day-to-day overview
Day 1-2
Seeds placed directly in pots or after taproot. Pots lightly moistened, propagator closed. No visible growth above ground.
Day 3
First action! 3 of the 5 pushing hypocotyl up with cotyledons splitting the soil. The other 2 show bulging – they’re catching up quickly.
Day 4
Full 100% germination! All 5 through the soil. Cotyledons slowly opening. Heights starting at 0.5-1.5 cm. The fastest plants are already showing the first true leaves.
Day 5-6
Even progress under LED + propagator.
4 plants: cotyledons + 1 set of true leaves (mostly 1-3 fingers)
1 seedling: cotyledons dominant, but growing through
Heights: 2-4 cm. Leaf color fresh light green to dark green. No leggy stretch thanks to good LED distance. Stems strengthening due to light airflow.
Day 7 (end of week 1)
Strong standing after week 1:
3 strong plants: 4-6 cm, 1 full set of true leaves + beginning of the second set
1 average: around 4 cm, cotyledons + 1 set of true leaves
1 slightly slower: 2.5-3 cm, cotyledons open, first true leaves visible
No losses, no damping-off or moisture issues. Leaves healthy, substrate balance perfect in small pots. Roots developing well – likely already visible at the bottom.
Conclusion week 1
5/5 germinated and healthy – Spliff Seeds quality proves to be top-notch again. Propagator + LED combo worked ideally: compact growth, no stress, strong root development. This sets the tone for a solid veg phase.
For week 2: slowly ventilate the propagator further (RH to 60-70%), keep adjusting LED distance as plants grow (closer if they stretch, further if leaves turn pale). Water still minimal, focus on roots filling the pot. Transplanting approaches as roots reach the bottom (around day 10-14).

Xpie77 Current status: Week 4 (end of pre-flower / late stretch)
Height: 40-65 cm (depending on training; without LST/SCROG it can be higher due to ×2.0-2.5 stretch)
Development: First pistils visible everywhere (since day 18-25), nodes closer together, small flower tops forming at the top and side branches. Stretch is now slowing down significantly – most plants stop growing in height.
Smell: Starting to become creamy/fruity (vanilla ice cream + citrus + light gas/diesel). Not super strong yet, but carbon filter is already essential.
Leaves: Dark green, thick, resin starting on sugar leaves. Possible light purple hues in stems (typical Gelato).
Nutrients: EC 1.2-1.5 (bloom nutrients), pH 6.2-6.5. Water generously with 30-40% runoff – plants are drinking a lot now.
Light: Hang at 40-50 cm (adjust if leaf curling/bleaching occurs).
Tips now:
Finalize LST/tie-downs for a flat canopy (now or never – stretch is almost over).
Check for Mg/Ca deficiency (yellow edges/spots in stretch – Gelato can be sensitive).
Lower humidity to 50-55% to prevent mold.
Week 1 flowering (first real flowering week – buds starting to bulk)
Week timing: ± Day 28-35 after starting 12/12 (or week 5 total if you call week 1 = seedling; here as "week 1 flowering" after stretch).
Height: Stabilizing around 50-90 cm (stretch is over – +0-5 cm max still).
Development:
Bud sites swelling: calyxes getting thicker and pointier, clusters forming.
Pistils exploding: lots of white hairs everywhere (buds becoming fluffy).
First real trichomes visible on sugar leaves and calyxes (clear → milky beginning).
Plants are now focusing 100% on flower growth – no new nodes anymore.
Smell: Becoming noticeably stronger: sweet creamy dessert (vanilla/ice cream), fruity, with a gassy/mint undertone. Odor control crucial from now on!
Leaves: Still healthy dark green, but lower fan leaves may start to yellow slightly (normal nutrient shift). Sugar leaves starting to be sticky/resinous.
Nutrients: EC 1.4-1.7 (bloom peak), introduce light PK boost (e.g., 13/14 or Plagron Green Sensation half dose). Stay at 30-40% runoff.
Temperature / humidity: 23-26°C day / 18-21°C night, humidity 45-50% (lower = more resin).
Light: 35-45 cm distance – BestVA can now penetrate well for thick buds.
Water: Larger volume per feeding (pots dry faster due to flowering stress).
Tips for this week:
Light defoliation: remove large fan leaves that cast shadows on bud sites (not too aggressively!).
Watch for nutrient burn (tips brown) – Gelato loves higher EC but don’t overfeed.
Increase ventilation – smell + humidity = mold risk.
Lower branches low & slow? Remove popcorn buds now for better airflow and top bud focus.
What to expect in the coming weeks (short preview)
Week 2 flowering: Buds double in size, trichome layer thicker, smell extreme.
Week 3-4 flowering: Bulk phase – buds harden, resin everywhere, pistils 50% brown.
Total flowering: 56-63 days (8-9 weeks) → harvest around week 8-9 flowering.
Expected yield: Still 300-425 g total (5 plants), provided the canopy is well filled.
You’re at a peak point: stretch is over, buds are really starting – this is where Gelato shows its magic (those thick, frosty colas!). Keep the EC stable, train down, and enjoy the smell development.
Xpie77 Current status: Week 6 flowering
Height: Around 60-90 cm (depending on training; with LST/SCROG in 11L pots, it remains well manageable and fills out the canopy nicely).
Development:
Buds are swelling nicely and becoming compact/dense. The tops (as seen in the close-up) are already heavily covered with trichomes – a thick, white “frosty” layer on sugar leaves and calyxes.
Pistils: Still mostly white and numerous (plants keep producing new hairs while the buds bulk up).
Leaves: Dark green with light purple hues (typical for GSC), especially on stems and fan leaves. Lower leaves are starting to yellow slightly (normal nutrient shift).
Smell: Now strongly creamy-vanilla ice cream with fruity and gas-like/mint undertones. Carbon filter needs to run 24/7 – Gelato is really loud at this stage!
Trichomes: In the photos, you can already see many reliable to milky trichomes. This is perfect for week 6; resin production is high (ideal for hash from extracts).
Nutrients: EC 1.5-1.8 (flowering nutrients with PK boost). Ensure 30-40% runoff to prevent salt buildup. Gelato loves stable EC but can be sensitive to overfeeding.
Environment: 23-26°C day / 18-21°C night, known 40-50% (lower = more resin). Good air circulation prevents mold in the dense buds.
Lamp: BestVA 415W at 30-40 cm distance – the plants seem to be capturing light well, considering the dense tops.
What does week 6 flowering mean for GSC?
This is the bulking phase where the tops really gain volume and density. Stretch is long gone, and the plants are fully focused on flower development. With setup (12/12 from seed, 11L pots), you now see the typical Gelato traits: your compact, sticky colas with a thick layer of trichomes. The purple accents and orange hairs often start to become more visible.
Compared to interim weeks:
Week 1 flowering: First pistils and small bud sites.
Week 4-5: Start of identified + smell development.
Week 6: Tops almost double in size, resin everywhere, smell at its strongest.
Tips specific for week 6-7
Defoliation / lollipopping: Remove some large fan leaves and the buds' shadows (not too much combined). Also, remove the lower popcorn buds for better airflow and energy to the tops.
Watering: Plants are drinking a lot now – give generously when the pot is half light. Never let them dry out completely.
Nutrients: Keep PK boosting (e.g., half dosage Bloom booster). If leaves yellow too quickly, check for Mg/Ca (box in flowering).
Humidity & temp: Keep it cool and dry for maximum resin. Nighttime dip helps with color development (purple).
Training: If there's still space, light forward light penetration.
Problems to watch for:
Too much moisture → botrytis in dense buds (prevent with good ventilation).
Nutrient burn (brown tips) → lower EC slightly.
BestVA hotspots → check for bleaching.
Outlook
Week 7-8 flowering: Buds further harden, pistils start to appear slowly and color to orange/brown. Trichomes go more milky → amber.
Week 8-9 flowering: Ripening. Flushing starts around week 7-8 (last 10-14 days pure water).
Total flowering time expectation: 56-63 days (8-9 weeks) from start of 12/12. Harvest likely around week 8-9 flowering.
Yield: With this development and 5 plants in 11L: still a stable 300-425 g dry total (60-85 g per plant). Good canopy + frost = potential on the higher side.
The plants look strong and resinous – that close-up shows exactly the “sugar layer” look that Gelato is known for. Beautiful purple stems and thick tops!
@SpliffSeeds, hey toppers! Yeah, they're doing great. Next week they'll be in a new environment. Thanks for the seeds and we're aiming for success! I'll do a weekly update starting next week, right now you can't see much because they're in small pots. ☀️☀️☀️
