Growing Wedding Cake with LST

What LST is

Low-stress training (LST) is the practice of gently bending and tying down branches to change a plant's shape without cutting it. The goal is to flatten the canopy so more bud sites get direct light, instead of one tall cola shading everything below it.

Unlike topping or fimming, LST doesn't wound the plant. You're just redirecting growth using the plant's natural response to light — auxins redistribute toward the new highest points, and lower side branches wake up and grow vertically ^[1][2]. It's the lowest-risk training method, which is why it's recommended for first-time growers.

Why growers use it on Wedding Cake

Wedding Cake (Triangle Kush x Animal Mints), bred by Seed Junky Genetics, has a few traits that make LST especially useful ^[3]:

• Strong apical dominance. Left alone, it pushes one big central cola and the lower branches lag behind. LST evens this out.
• Moderate stretch in flower. It typically stretches 1.5-2x its veg height in the first 2-3 weeks of 12/12, which can blow past your light's optimal range in a tent Weak / limited.
• Dense, heavy buds. Side branches that get good light during veg can hold respectable colas — but only if they got the light to develop.
• Slightly brittle stems on some phenos. LST done early, while stems are still flexible, avoids the snap risk of bending a woody mid-flower plant Anecdote.

The "indica/sativa" labels you'll see on seed pages don't reliably predict structure or effects — that's marketing folklore ^[4]. Judge each Wedding Cake pheno by what it actually does in your tent.

When to start and stop

Start: Once the plant has 4-5 nodes and the stem is flexible but not floppy — usually 3-4 weeks from seed, or about a week after a clone is well-rooted and growing vigorously.

Continue through veg: Keep tying down new growth as it rises above the canopy. This is the main work phase.

Taper in early flower: You can keep doing light LST for the first 2-3 weeks of 12/12 (the stretch phase). After stretch ends and buds start forming, stop. Bending flowering branches risks snapping them, and the plant won't redirect growth meaningfully at that point Weak / limited.

How to do it, step by step

1. Prep the pot. If you're using a fabric pot, punch or burn small holes around the rim for tie anchor points. For plastic pots, you can use the rim itself or push small stakes into the soil.

2. Wait for the right stage. Plant should have 4-5 nodes. The main stem should bend without creaking.

3. First bend. Gently arch the main stem sideways and tie it down so the top is now lower than (or level with) the side branches. Use soft plant wire, garden tie tape, or pipe cleaners — anything that won't dig into the stem. Never use bare wire or fishing line directly against the plant.

4. Watch the response. Within 2-4 days, the side branches will start growing upward toward the light. The original tip will also curve back up.

5. Tie down the new tops. As branches rise above your target canopy height, tie them down too. The goal is a flat, even canopy where every bud site sits at roughly the same height under the light.

6. Tuck and rotate. Between tie-downs, you can tuck large fan leaves out of the way to expose lower bud sites. Rotate the pot a quarter turn every few days for even light.

7. Combine with a ScrOG (optional). Many growers run LST into a screen of green (ScrOG) net, weaving branches horizontally under the mesh. This is the most efficient setup for Wedding Cake in a small tent Weak / limited.

8. Stop bending in flower. After week 2-3 of 12/12, lock the structure in and let the buds finish.

Common mistakes

• Starting too late. Once the lower stem turns woody, it will snap instead of bend. If you're past that point, super-cropping (controlled stem crushing) is a better tool than LST.
• Tying too tight. A taut wire will girdle the stem as it thickens. Leave slack and check ties weekly.
• Using thin wire or string. Bare metal or fishing line cuts into stems. Use coated wire, soft tape, or rubber-coated twist ties.
• Bending only once. LST isn't a one-time event. You're managing canopy height continuously for the whole veg cycle.
• Ignoring the stretch. Wedding Cake stretches hard in early flower. If you trained to a flat canopy at flip, expect it to rise 30-60 cm in the next two weeks and plan light height accordingly.
• Defoliating aggressively at the same time. Stacking heavy defoliation onto LST stresses the plant. Pick one major intervention at a time.

Related techniques

• Topping / FIMming: Cutting the apical tip to force two (or more) new mains. More aggressive than LST and can be combined with it.
• ScrOG (Screen of Green): A horizontal net that mechanically enforces a flat canopy. Pairs naturally with LST.
• Super-cropping: Pinching and bending stems hard enough to crush the inner tissue. Higher risk, used on stems too stiff for LST.
• Mainlining / manifolding: A structured topping + LST protocol that builds a symmetrical, evenly-yielding plant from the start.
• Defoliation: Removing fan leaves to open up bud sites. Evidence on yield impact is mixed Disputed.
