Indica Dominant · ILGM Genetics
Gold Leaf
Gold Leaf is the ILGM in-house strain bred by Robert Bergman over a multi-year selection program. The cross blends an unnamed indica heavy-yielder with a sativa-dominant hybrid that adds clarity to the high. The strain is sold only through ILGM and its affiliates and finishes in roughly nine weeks with large, dense colas and a citrus-spice terpene profile.

Terpene profile
The aromatic compounds below shape how Gold Leaf smells, tastes, and ultimately feels in the body.
- dominant
Limonene
Uplifting citrus — typically associated with mood elevation and stress relief.
- secondary
Caryophyllene
Peppery and spicy — the only terpene that binds CB2 receptors, studied for anti-inflammatory action.
- secondary
Myrcene
Sedating, musky, herbal — commonly linked to couch-lock effects.
- minor
Humulene
Hoppy and earthy — appetite-suppressing and shared with hops and sage.

Lineage
Gold Leaf traces to Proprietary indica × Proprietary hybrid. The cross sits in the ILGM proprietary family, which influences both the terpene profile and the flowering structure described above.

Feed schedule for Gold Leaf
These EC and NPK targets are starting points calibrated for the strain's Indica lean and easy difficulty rating — not gospel. Drop 15-20% off any EC ceiling on your first run and let the plant tell you where it actually wants to feed.
Suggested feed schedule
- Late veg
- 1.1-1.3 EC
- Early flower
- 1.2-1.4 EC, NPK 2-3-4
- Mid flower
- 1.5-1.7 EC, NPK 1-4-6
- Late flower
- 1.3-1.5 EC
- Final week
- Plain pH-balanced water for the last 5-7 days.

What to expect through the grow cycle
Gold Leaf is documented with a 10-week flower and a compact stretch typical of indica-leaning structure. The visual below maps a documented 14-week cycle built from 4weeks of vegetative growth and the strain's published flowering window.
Published grow reports for Gold Leaf concentrate the most observational notes on the late-flower ripening window. This timeline is descriptive — it reflects what reports document, not a how-to. Actual week-to-week behaviour varies with phenotype, light intensity, pot size, and environment.
Phase details
- Veg (weeks 1-4)
- The documented vegetative period for Gold Leaf. Plants establish root structure, leaf canopy, and node count before flower triggering, with a easy difficulty rating shaping how forgiving the early canopy work tends to be.
- Stretch (weeks 5-8)
- Gold Leaf is documented as having moderate stretch. Reports describe the plant roughly doubling in height during this phase as the indica-leaning structure establishes its final flowering frame.
- Bud sites (weeks 9-10)
- Pre-flowers form at the nodes and calyxes begin to develop. Grow reports for Gold Leafnote this as the window where the canopy's eventual bud distribution becomes visible.
- Bud development (weeks 11-12)
- Flowers thicken and calyxes fatten through this phase. Documented Gold Leaf runs show the bulk of visible flower mass accumulating here, with resin production accelerating toward the end.
- Ripening (week 13)
- Trichomes transition from clear toward cloudy and amber. Reports for Gold Leaf describe the Limonene-led terpene profile maturing through this window, with aroma sharpening week over week.
- Final (week 14)
- Calyx swelling is documented as complete and the harvest window opens. Published Gold Leaf runs end here, within the 9-10 week flowering range reported by the breeder.

Common questions about Gold Leaf
Can I buy Gold Leaf seeds from anywhere besides ILGM?
No. Gold Leaf is an ILGM-exclusive strain. Any third-party listing of it should be treated as suspect.
How much does Gold Leaf actually yield?
Indoor reports center around 550-650 g/m² with a SOG-style canopy. Outdoor plants can clear 800 grams in long Mediterranean seasons.
