Setup & Growing Conditions

Before you pop those seeds, make sure your grow space is dialed. Slurricane is a medium-height plant with dense, resin-heavy buds, meaning airflow, humidity control, and support are all essential to prevent mold and maximize quality.

🌱 Ideal Growing Conditions

• Light Cycle (Veg): 18/6
• Light Cycle (Flower): 12/12
• Indoor Temp (Lights On): 72–78°F (22–25°C)
• Humidity (Veg): 55–65%
• Humidity (Flower): 40–50%
• Soil pH: 6.0–6.5
• Water pH: 6.2–6.8

🛠️ Recommended Equipment

• 3×3 or 4×4 grow tent (min. 60” height)
• Full-spectrum LED grow light (300W+)
• Clip-on fans + inline ventilation system
• Fabric pots (3–5 gallon) with drainage
• Nutrient line (veg, bloom, and micronutrients)
• Digital hygrometer + pH/EC meter

Germination

To give your Slurricane seeds the best possible start, stick with the tried-and-true paper towel method. It’s easy, effective, and it’s the only method covered under our seed guarantee.

🌱 Germination Steps

1. Moisten a paper towel (damp, not soaked).
2. Fold it and place your seeds between the layers.
3. Set it between two paper plates to maintain darkness and airflow.
4. Keep in a warm area (72–78°F / 22–25°C).
5. Check daily. Taproots usually appear within 24–72 hours.

⚠️ Do NOT seal seeds in plastic or Tupperware. That traps moisture and can cause rot.

When the taproot reaches around ½ inch, carefully transfer each seed into its final growing medium — about ½ inch deep.

• Water: Only when top inch feels dry (pH 6.2–6.5)

⚠️ Tips

• Keep airflow light and indirect
• Avoid touching seedlings or shifting light too early
• Watch for damping-off (slim stems or wilting = too wet)

Week 2: Early Veg & Training Prep

Slurricane begins picking up steam in Week 2, pushing out new leaf sets and establishing a stronger root zone. This is the ideal time to start light LST (Low Stress Training) or prep for topping in Week 3.

🌿 What to Expect

• 3–4 leaf nodes
• Noticeable vertical growth
• Stem begins thickening
• Root mass expanding below surface

🌞 Environment & Care

• Temp: 72–78°F
• RH: 60–65%
• Light Cycle: 18/6
• Water: Increase slightly as plant drinks more
• Nutrients: Start low-dose veg nutrients (¼ strength)

🔧 Training (Optional)

• Begin gentle LST by bending the main stem outward and tying it down
• Or prep for topping in Week 3 by identifying the 4th–5th node

Week 3: Veg Growth & Training

This week, Slurricane kicks into full vegetative gear. Her branches stretch out, her leaves widen, and she starts showing signs of her potential. Now’s the time to top or continue LST to encourage a flat, even canopy.

🌿 What to Expect

• 5–6 nodes developed
• Vigorous branch growth
• Thicker main stem
• Root zone fully active

🛠️ Training Moves

• Top the main stem above the 4th or 5th node to promote two new colas

• Defoliate lower leaves sparingly if they block airflow or light

💧 Feeding & Environment

• Nutrients: Step up to ½ strength veg nutes (N-heavy)
• Watering: Water deeply but less often
• Temp: 72–78°F
• RH: 55–65%
• Light: PPFD ~400–500 µmol/m²/s

Week 4: Late Veg & Pre-Flower Prep

Your Slurricane plant should now be looking strong, symmetrical, and ready to flip. Use this week to finalize training and prepare for the flower stage. A flat canopy = more even bud development.

🌿 What to Expect

• Lush foliage and strong side branches
• Bushy, compact growth with multiple tops (if topped or LST applied)
• Roots filling the pot

🔧 Final Veg Work

• Complete any final LST adjustments
• Tuck or lightly defoliate large fan leaves blocking bud sites
• Ensure pot size is final (3–5 gal ideal)
• Check pH and runoff; dial it in before flip

🌞 Environment & Feeding

• Light Cycle: Stay on 18/6
• PPFD: 500–600 µmol/m²/s
• Temp: 72–78°F
• RH: 50–60%
• Nutrients: Full veg strength

Next step: Flip to flower at the end of this week or early next.

Week 5: Flower Week 1

Time to flip! Slurricane enters her flowering phase and starts stretching. This week is all about supporting that early vertical growth and transitioning her nutrient profile.

🌸 What to Expect

• Stretch begins; plant can double in height over next 2–3 weeks
• Pre-flower hairs (pistils) start forming at node sites
• Aroma begins to build subtly

🌿 Environment & Feeding

• Light Cycle: 12/12
• PPFD: 600–700 µmol/m²/s
• Temp (Day/Night): 75–78°F / 68–70°F
• RH: 45–55%
• Nutrients: Start flower nutes (low N, higher P/K) at 75% strength
• Training: Adjust LST to keep canopy even, no topping now!

🌬️ Maintain good airflow; stretching plants = more foliage = higher risk of mold if humidity spikes.

Week 6: Flower Week 2

Slurricane is officially in bloom. Her stretch continues but begins to slow by the end of the week. Pistils multiply and form early bud sites at each node. Time to keep her dialed in and pest-free.

🌸 What to Expect

• Stretch slows by Day 42
• Bud sites stack along stems
• More pistils = stronger aroma (fruity, creamy funk begins)

🌿 Environment & Feeding

• PPFD: 700–800 µmol/m²/s
• Temp: 74–78°F (Day), 66–70°F (Night)
• RH: 45–50%
• Nutrients: Flower feed at full strength (watch for nute burn)
• Water: Increase volume slightly, she’s thirstier now

🛡️ Tips

• Check for signs of overfeeding or clawing
• Consider light leaf tucking to expose lower bud sites
• Stay clean; flowering plants are sensitive to mold and bugs

Week 7: Flower Week 3

Slurricane shifts from stretch to stack. The vertical growth slows down, and now it’s all about bud bulking. The plant begins to focus energy on building dense, trichome-rich flowers.

🌸 What to Expect

• Buds thicken and take shape
• Pistils grow longer and more abundant
• First frost: Trichomes appear on leaves and sugar tips
• Aroma becomes stronger (berry, creamy, earthy)

🌿 Environment & Feeding

• PPFD: 750–850 µmol/m²/s
• Temp: 72–77°F
• RH: 40–45%
• Nutrients: Continue full-strength bloom feed with CalMag support
• Watering: Regular intervals; avoid overwatering as buds swell

🛡️ Maintenance

• Light defoliation if humidity rises
• Ensure good air movement through buds
• Support branches if necessary; Slurricane gets chunky

Week 8: Flower Week 4

Slurricane is stacking hard now. Her buds grow chunkier, trichome production surges, and the creamy-berry funk intensifies. This is the phase where your grow starts to look and smell incredible but also needs precision.

🌸 What to Expect

• Buds swell and become denser
• Trichomes multiply, leaves look frosty
• Pistils may begin to darken at tips
• Strong, sweet, creamy aroma fills the tent

🌿 Environment & Feeding

• PPFD: 800–900 µmol/m²/s

🛡️ Pro Tips

• Watch for mold in dense colas, good airflow is non-negotiable
• Defoliate if large fan leaves block bud sites
• Check trichomes under a loupe by the end of this week, some might be cloudy

Week 9: Flower Week 5

Slurricane’s buds are getting fat and heavy. Most pistils are curling inward, and trichomes are rapidly developing. You’re now entering the final bulk and ripening phase. Every detail counts.

🌸 What to Expect

• Buds reach peak size and density
• Pistils turn orange/brown and begin to recede
• Trichomes mostly cloudy, some amber appearing
• Aroma is loud and complex (berry, cream, earthy)

🌿 Environment & Feeding
