Low-stress training (LST) is the top pick for most growers, because it shapes the canopy without cutting the plant and lets a beginner see results in the same week. The techniques below are ranked against five criteria: how much stress the plant absorbs, how long recovery takes, what gear you need, how much light reaches lower bud sites, and whether the method fits an indoor tent, a balcony, or an outdoor plot.

How to compare training techniques

Every method below changes plant architecture, which changes how light and air move through the canopy. Before you pick one, answer these questions.

  • Stress load: bending and tucking keep the plant intact. Cutting, pinching, and crushing open wounds that need time to seal.
  • Recovery window: gentle bending needs no downtime. Topping and supercropping stall vertical growth for several days to a week.
  • Gear: LST needs soft ties or wire. SCROG needs a screen. SOG needs many clones or seeds instead of one large plant.
  • Light penetration: a flat, even canopy exposes more bud sites than a single tall cola.
  • Environment: outdoor plants have wind, rain, and pests working against open wounds. Indoor plants give you control over temperature, humidity, and airflow.

Low-stress training (LST)

You bend the main stem and side branches sideways, then hold them in place with soft plant ties, garden wire, or a trellis. The plant responds by redistributing growth hormones toward the branches that now sit higher, so the canopy spreads instead of stretching upward.

Pros

  • No cuts, so no open tissue for pathogens.
  • Works on autoflowers and photoperiod plants alike.
  • Cheap: ties and clips cost very little.
  • You can adjust the shape any day of the grow.

Cons

  • Slower to build a wide canopy than topping.
  • Stems that are already woody resist bending and can snap.
  • Demands weekly attention to keep ties from cutting into stems.

Use it if: you grow in a tent with limited height, you run autoflowers, or this is your first trained grow.

Topping and FIMing

Topping removes the growing tip above a node, which ends apical dominance and pushes two shoots from that node. FIMing pinches most of the tip and often produces four or more shoots from the same site.

Pros

  • Doubles the number of main colas from a single cut.
  • Keeps plants short in low tents.
  • Creates an even canopy with less tying later.

Cons

  • Stress delays growth for several days.
  • Poor timing during flower can cost you yield.
  • Not a good fit for autoflowers with a short vegetative window.

Use it if: you grow photoperiod plants indoors and want many top colas from one plant.

Screen of Green (SCROG) and Sea of Green (SOG)

A SCROG uses a horizontal screen. You weave branches through the openings during stretch, which levels the canopy and forces lower sites into full light. SOG skips the screen and flowers many small plants at once, packing the floor with single-cola plants.

Pros

  • SCROG gives the most even light distribution per square foot.
  • SOG finishes fast and needs almost no training labor.
  • Both make trimming and inspection easier because the canopy is uniform.

Cons

  • SCROG plants cannot be moved once woven in.
  • SOG requires a steady supply of clones or many seeds.
  • Dense canopies need strong airflow to avoid mold.

Use it if: you have a fixed indoor space and want to maximize grams per square foot. Choose SOG when you want a short cycle, SCROG when you want fewer, larger plants.

Supercropping and monster cropping

Supercropping softens a stem between your fingers and folds it over without breaking the outer skin. Monster cropping takes clones from a flowering plant and revegetates them, which produces bushy, multi-branch growth.

Pros

  • Supercropping controls height late in stretch without removing growth.
  • The damaged bend forms a knuckle that supports heavy buds.
  • Monster cropping turns one flowering plant into many bushy clones.

Cons

  • Bends can snap if you rush or work a dry stem.
  • Revegetated clones take weeks to return to normal growth.
  • Both methods need clean hands and tools.

Use it if: a plant is outgrowing your tent, or you want to reuse genetics from a plant already in flower.

Defoliation and lollipopping

Defoliation removes selected fan leaves to open light paths. Lollipopping strips the lower third of a plant that receives little light and typically produces airy, low-weight flower.

Pros

  • Improves airflow, which lowers mold risk in humid rooms.
  • Sends energy to top bud sites instead of shaded lower growth.
  • Makes harvest and inspection faster.

Cons

  • Over-stripping removes the leaves that drive photosynthesis.
  • Heavy defoliation during flower can reduce final weight.
  • Results vary by strain and light intensity.

Use it if: your canopy is dense, humidity runs high, or lower sites are clearly shaded out. Take leaves in small passes and wait a few days before the next one.

Timing and recovery

Do structural work during vegetative growth. Topping, supercropping, and mainlining all land best when the plant has at least three or four nodes and weeks of stretch ahead of it. Once flowering starts, keep to bending, tucking, and light leaf removal. Give plants a few days between interventions, watch new growth for a day or two, and keep temperature, humidity, and watering steady so recovery is quick.

After harvest: what training does to your material

Training changes the ratio of top flower to lower larf. Tighter, well-lit canopies tend to yield denser flower, while shaded lower sites give you trim. If you grow hemp or high-CBD varieties, that trim still carries cannabinoids and is worth keeping for oil or topical projects. Whatever you make from it, source material from plants you know, and buy CBD only from suppliers that publish third-party lab results for potency and contaminants.
