Genetics: White Runtz ร Jet Fuel Gelato โ an Indica-dominant hybrid with strong early stretch but a compact final structure.
Stretch phase: Usually lasts until day 21โ24 after switching to 12/12.
Stretch factor: About 1.7ร to 2.2ร the height at the flip.
โ Example: if your plants were 50 cm tall at flip, theyโll likely finish around 85โ110 cm.
Final height (indoors, 1.2 m tent): Typically under 1 m if topped and trained properly.
Side branches: Very vigorous โ they create thick, even tops, ideal for SCROG or SoG setups.
Recommendations for your current stage (Day 16 of Flower):
1. Final defoliation window:
This is your last opportunity to thin out large fan leaves that are completely shading lower sites. After this week, avoid major defoliation โ youโll want to keep as much photosynthetic surface as possible for flower development.
2. Light intensity & distance:
Jokerz can handle strong light but dislikes excess heat.
Target around 850โ950 ยตmol/mยฒ/s PPFD, keeping a 30โ40 cm distance from the canopy.
3. Nutrient transition (now in mid-stretch):
Gradually reduce nitrogen to about 75 % of your veg level.
Increase phosphorus and potassium as you enter week 3.
4. Height management:
If your tops are around 60โ70 cm tall right now, expect another 10โ20 cm of upward growth.
Keep at least 25 cm of final clearance between the light and canopy.
If it gets too close, you can supercrop (gently bend the tallest tops).
Big up to all you ganja farmers ๐๐ keep growing and be nice ๐๐
