Sea of Green (SOG): Many small plants for quick harvests

Sea of Green (SOG) is one of the most efficient cultivation methods for fast, frequent harvests:

**SOG basic principle:**

*Concept:*

- Many small plants instead of a few large ones

- Short vegetative phase (2-4 weeks)

- Early flowering cycle

- High plant density

- Fast harvest cycles

*SOG advantages:*

- Harvest every 8-10 weeks

- Less training required

- Consistent canopy height

- Efficient light utilisation

- Risk distribution

*SOG disadvantages:*

- More plants = more seeds/clones

- Higher initial costs

- More pots and space

- More complex irrigation

- Legal aspects (number of plants)

**Optimal plant density:**

*Standard densities:*

- 16-25 plants per m² (small pots 6-11L)

- 9-16 plants per m² (medium pots 11-15L)

- 4-9 plants per m² (large pots 15-19L)

- Depending on variety and vegi time

*Pot sizes for SOG:*

- 6-8L: Very fast harvests, minimal vegi

- 8-11L: Standard SOG, good balance

- 11-15L: Larger SOG plants

- Over 15L: No longer true SOG

*Spacing calculation:*

- 1m² = 100cm × 100cm

- 16 plants = 25cm × 25cm grid

- 25 plants = 20cm × 20cm grid

- Enough space for air circulation

**SOG timeline:**

*Week 1-2 (germination/rooting):*

- Germinate seeds or root clones

- Low light (200-300 PPFD)

- High humidity (70-80%)

- Careful watering

- 18/6 or 20/4 light cycle

*Week 3-4 (Short vegetative):*

- Minimal training (LST only)

- Medium light (400-500 PPFD)

- First light fertilisation

- Humidity 60-70%

- At 20-30cm height in flower

*Week 5-12 (flowering phase):*

- 12/12 Light cycle

- Full light (600-1000 PPFD)

- Flowering fertiliser programme

- Humidity 40-50%

- Minimal further interventions

**Variety selection for SOG:**

*Ideal for SOG:*

- Indica-dominant varieties

- Uniform growth

- Minimal stretch

- Uniform flowering time

- Compact structure

*Recommended SOG varieties:*

- Northern Lights: Very uniform

- Critical Mass: Heavy flowers

- White Widow: Proven for SOG

- Afghan Kush: Compact and dense

- Skunk #1: Uniform growth

*Less suitable:*

- Sativa-dominant strains (too much stretch)

- Strains that grow unevenly

- Very training-intensive genetics

- Slow flowering strains

**Clones vs. seeds for SOG:**

*Clone advantages:*

- Identical genetics

- Uniform size and timing

- No gender risk

- Predictable results

- Optimal for SOG

*Clone procurement:*

- Own mother plants

- Local grower community

- Commercial suppliers

- Check quality and health

*Seeds for SOG:*

- Feminised seeds only

- Same strain from the same breeder

- More variation in size/timing

- Higher initial cost

- Backup plan for failures

**Optimise SOG setup:**

*Lighting:*

- Even light distribution important

- Several smaller LEDs better than one large one

- PPFD mapping for uniformity

- No hot spots or dark areas

*Irrigation:*

- Automatic systems recommended

- Drip system or flood & drain

- Consistent humidity important

- Drainage for all pots

*Air circulation:*
