**Report on the Variety “Grandfather’s Wormwood”

Including Genetic Background of ABC, GPP, and Fern-Leaf Mutations**

1. Introduction

Grandfather’s Wormwood is a complex multi-hybrid cannabis variety developed over five years of intensive selection and stabilization. It unites several rare and visually striking cannabis mutations—including ABC (Australian Bastard Cannabis), Freakshow, Superfreak, and GPP lines—combined with hardy outdoor genetics and Ruderalis influence.

The result is an extremely robust, high-yielding, and uniquely disguised outdoor cultivar, known for its fern-leaf morphology, early finishing time, vigorous growth, and sticky, high-quality resin.

2. Genetic Background & Diversity

2.1 ABC – Australian Bastard Cannabis (IBL)

ABC is a rare mutant landrace from Australia, visually unlike traditional cannabis.

Key features of ABC:

• deeply lobed, smooth, non-cannabis-like leaves
• compact and discreet plant structure
• exceptionally short flowering time
• ideal for guerilla growing
• terpene profile: kerosene, fennel, lemon, pine
• indoors: 8–10 weeks flowering
• outdoors: finishes one month earlier than standard varieties
• stabilized as an IBL (inbred line)

Contribution to Grandfather’s Wormwood:
ABC provides the clustered leaf and early-mutation traits, forming the foundation of the fern-mutation development.

2.2 Freakshow & Superfreak (Fern-Leaf Mutations)

Originally popularized by Kalyseeds, these mutations are responsible for the iconic fern-like foliage.

Characteristics of the fern-leaf mutation:

• extremely dissected, fern-like leaves
• significantly increased leaf biomass
• enhanced photosynthesis → stronger growth & higher yields
• improved resistance to storms, rain, hail
• high structural flexibility

Role in Grandfather’s Wormwood:
Through multi-step hybridization, the fern-leaf mutation was intensified and made denser than the original Freakshow.
This leads to a more powerful leaf structure, higher stress tolerance, and better camouflage.

2.3 GPP & GPP-Neon (Ruderalis-Based Mutated Lines)

GPP lines combine Ruderalis traits with leaf-type mutations and strong color expression.

GPP-Neon features:

• single-fingered, serrated leaves resembling lemon or nettle leaves
• up to 30% variegated or albino plants
• intense color transitions: pink, yellow, white, green
• cold temperatures enhance red & rose tones
• floral colors reflect the leaf palette
• large leaf size (adult hand-sized)
• green phenotypes → very high yields
• variegated forms → lower but still good yields
• flavor: fermented forest berries, elderberry, fruit liqueur, wine
• mild, uplifting effect with medical potential
• average THC but likely rich in minor cannabinoids (CBC, CBG, CBD)

Contribution to Grandfather’s Wormwood:
GPP adds:

• Ruderalis-based early flowering
• color enhancement
• increased resin production
• aroma complexity
• enhanced cold tolerance
• additional leaf-mutation traits

3. Development of “Grandfather’s Wormwood”

3.1 Breeding Method

Over five years, only the strongest and healthiest phenotypes were retained.
Selection focused on:

• mutation stability (fern-leaf)
• resistance to mold and cold
• high resin production
• outdoor performance
• uniformity and yield

The final hybrid combines: ABC × Freakshow × Superfreak × GPP × Ruderalis × Outdoor landraces
→ forming a new generation of fern-leaf high-performance outdoor cannabis.

3.2 Morphology & Growth

• large, outward-stretching Sativa structure
• very dense fern-like foliage
• outstanding wind, storm, and rain resistance
• strong branching and stable stems
• high resin production with sticky consistency
• ideal for camouflage in gardens, edges, overgrown areas

4. Agricultural Characteristics

4.1 Flowering & Maturation

Thanks to its Ruderalis ancestry, flowering starts very early.

• fully ripe by late September
• frost nights turn buds deep purple/black
• cold boosts resin quality and terpene strength

Special Feature: Successive Bud Harvesting

If the main buds are harvested gradually from mid-September onwards:

• the plant compensates → secondary buds swell dramatically
• allows multiple partial harvests
• extends plant life cycle
• maximizes total yield

If harvested all at once:

• plant stops growth and dies (Ruderalis life cycle)
• no compensatory budding

4.2 Resin & Aroma

Unlike some old mutation lines with dry, crumbly resin, Grandfather’s Wormwood produces:

• sticky, oily, dense resin
• ideal for hash production
• aromas intensify after cold nights

4.3 Mold Resistance

The fern-leaf structure and hybrid vigor make the plant:

• highly resistant to mold and rot
• reliable in wet northern climates

5. Cultivation Guidelines

5.1 Location

• semi-shade to full sun
• deep, humus-rich soil
• optimized for outdoor growing in Central and Northern Europe

5.2 Sowing Recommendations

• indoor pre-grow: from March
• transplant outdoors: after mid-May (no frost)
• direct outdoor sowing: April–July

Late sowing (July):

Behaves like an auto:

• rapid flowering
• large central cola
• heavy resin production
• very compact growth

Seedlings tolerate –5°C, but pre-grown plants are frost-sensitive.

6. Comparative Overview of Mutation Sources

7. Summary

Grandfather’s Wormwood is one of the most advanced outdoor fern-mutation hybrids to date.
It combines:

• dense fern-leaf morphology
• extreme robustness & weather resistance
• early maturation (late September)
• sticky, high-quality resin
• multi-harvest potential
• low visibility due to leaf shape
• high yields under outdoor conditions

This makes it a uniquely powerful strain for growers seeking stealth, productivity, and exotic genetics in an outdoor environment.
