fast version seeds are popular among growers who want the speed of autoflowers combined with the control and yields of photoperiod plants. Because these genetics flower quickly after the light cycle changes, applying the right training techniques at the right time is essential to maximize yield without stressing the plant. Below are the most effective training methods specifically suited for Fast Version Seeds.

Understanding the Growth Window

Fast Version plants typically have a shorter vegetative phase than regular photoperiod strains. This means training must be done early and gently. Most training should be completed within the first 2–3 weeks of vegetative growth to avoid interfering with flowering development.


1. Low-Stress Training (LST)

Low-Stress Training is the most recommended technique for Fast Version Seeds.

How it works:

  • Gently bend and tie down branches to create an even canopy
  • Allows better light penetration to lower bud sites

Benefits:

  • Minimal recovery time
  • Increased bud sites
  • Ideal for outdoor and indoor growers

Best time to apply:
Week 2 of vegetative growth


2. Topping (Use With Caution)

Topping involves cutting the main growth tip to encourage multiple colas.

Pros:

  • Promotes bushier growth
  • Can significantly increase yields if done early

Cons:

  • Causes short recovery time
  • Not suitable if plants are already stressed

Best practice:
Top only once, above the 4th or 5th node, and only if the plant is healthy and vigorous.


3. FIM (Fuck I Missed) Technique

FIM is a softer alternative to topping and can work well with Fast Version Seeds.

Advantages:

  • Less stress than topping
  • Can produce 3–5 main colas
  • Faster recovery

When to FIM:
Early vegetative stage (around day 14–18)


4. Defoliation (Light and Selective)

Fast Version plants benefit from light defoliation but not aggressive leaf removal.

Guidelines:

  • Remove only large fan leaves blocking bud sites
  • Never defoliate heavily during early flowering

Benefits:

  • Improved airflow
  • Better light exposure
  • Reduced risk of mold outdoors

5. Lollipopping (Limited Use)

Lollipopping involves removing lower growth that receives little light.

Best approach:

  • Light cleanup of the lowest branches only
  • Avoid heavy stripping due to short veg time

Ideal timing:
Just before switching to flowering


6. Avoid High-Stress Techniques

Some methods are not recommended for Fast Version Seeds:

  • Mainlining
  • Manifolding
  • Supercropping (unless very gentle)

These techniques require longer recovery periods that Fast Version plants may not have.


Outdoor Training Tips

  • Use soft plant ties or garden wire
  • Train plants outward rather than upward
  • Start early to keep plants low-profile and wind-resistant

Final Thoughts

Fast Version Seeds respond best to early, low-stress training that enhances light exposure without slowing growth. LST combined with mild topping or FIM can dramatically improve yields while preserving the fast harvest times these genetics are known for. The key is timing—train early, be gentle, and stop once flowering begins.
