Cannabis Cultivation Methods: SCROG, SOG & More

SOG – Sea of Green

Principle

Many small plants are placed close together, switched early into flowering, and each forms one dominant main cola.

Characteristics

• Approx. 10–25 plants per m²
• Short vegetative phase (often 1–2 weeks), ideal with cuttings
• Little to no training

Advantages

• Fast harvest cycles
• Very high yield per area
• Minimal shaping work

Disadvantages

• Many plants (legal risk depending on country)
• Less control per plant

Best for

Growers with many clones and a focus on speed.

SCROG – Screen of Green

Principle

Few plants are trained horizontally under a screen until an even canopy of buds forms.

Characteristics

• Approx. 1–4 plants per m²
• Longer vegetative period due to training
• Branches spread under the net, then switched to flowering

Advantages

• Optimal light utilization
• Very high yield per plant
• Fewer plants required

Disadvantages

• Requires more maintenance & experience
• Plants are difficult to remove individually

Best for

Growers with limited plant counts focusing on quality and efficiency.

LST – Low Stress Training

Principle

Branches are gently bent and fixed to distribute light evenly; no cutting involved.

Advantages

• Minimal stress, low risk
• More usable bud sites

Disadvantages

• Requires regular adjustment

Best for

Beginners and low-height grow spaces.

HST – High Stress Training

Principle

Intentional intervention (topping, fimming, supercropping) to promote bushy growth and multiple main colas.

Advantages

• Dense, high-yielding canopies
• Uniform bud size

Disadvantages

• Requires experience, plants need recovery time

Best for

Advanced growers with good climate management.

Mainlining / Manifolding

Principle

Combination of LST & HST; symmetrical structure creating e.g. 8 or 16 identical main colas.

Advantages

• Very even canopy
• Ideal for SCROG setups

Disadvantages

• Long veg phase, requires precise work

Best for

Perfectionists with time.

Hydroponic Systems (DWC, NFT, Aeroponics)

Principle

Roots grow in a nutrient solution or mist instead of soil; rapid uptake, vigorous growth.

Advantages

• Very fast growth and high yield
• Precise nutrient control

Disadvantages

• Technically demanding
• Errors have immediate effects

Best for

Tech-savvy growers.

Combinations

• LST + SCROG for maximum light efficiency
• Mini-SCROG over a SOG field for even height
• Mainlining as preparation for SCROG
