I'm sorry to hear about the accident with your Royal Gorilla plant. When a cannabis plant is damaged, especially a significant branch like a top branch, it can be quite a shock to the plant. However, cannabis plants are known for their resilience and ability to recover from damage, though the success of recovery can vary.
Since you've reattached the branch quickly using a clamp and tape, there's a chance the plant might be able to repair itself. This kind of repair is similar to the process of grafting, where parts of plants are joined together so they continue to grow as one plant. Here are some points to consider:
1. **Observation:** Keep a close eye on the damaged area. If the branch remains green and starts to show new growth, it's a good sign. If it starts to wilt or turn brown, it may not have reattached successfully.
2. **Support:** Make sure the clamp and tape are secure but not too tight. You want to allow for some natural growth and movement.
3. **Healing Time:** It can take several days to a week or more for the plant to attempt to heal itself. Be patient.
4. **Plant Health:** Ensure the plant is otherwise healthy - adequate water, nutrients, and light are essential for recovery.
5. **Clean Cut:** If the branch doesn't recover and starts to die, you may need to cleanly cut it off to prevent any potential for disease or rot to spread to the rest of the plant.
6. **Reduced Stress:** Try to minimize stress on the plant from other sources. This includes maintaining a stable environment (temperature, humidity, light cycles).
7. **Potential for Topping:** If the branch doesn't survive, the plant will likely respond by growing out its side branches more, which can be beneficial in its own way. This is similar to a technique known as "topping," used to encourage bushier growth.
8. **Watch for Infection:** Keep an eye out for signs of infection at the wound site. If the area looks unhealthy, take action to remove the affected parts.
Remember, each plant's ability to recover from damage varies depending on its overall health, the strain, and the extent of the injury. Even if this branch doesn't survive, your plant can still grow successfully with proper care and attention :-)
