Topping vs FIM: topping removes the shoot tip completely for 2 main shoots, FIM removes 75% for 3–4 shoots — timing, technique and recovery explained.
Topping: Complete removal of the shoot tip, produces 2 main shoots. FIM (F*ck I Missed): Remove 75% of the shoot tip, produces 3-4 shoots. Timing: 5-6 nodes for topping, 4-5 for FIM. Recovery: 7-14 days. Topping more precise, FIM higher yield but more unpredictable. Never apply during flowering.
Topping removes the entire shoot tip, resulting in two main shoots, while FIM removes 75% of the tip, thereby promoting 3–4 shoots.
Both techniques should be used when the plant has 4–6 internodal segments, typically during the vegetative phase.
The recovery time varies, but is generally 1–2 weeks, depending on the plant species and growing conditions.
