Feb 8th I topped my peppers in the GH and you can see the new growth already. Not all plants will respond this quick, these took off because the side shoots were trying to develop when I topped it.
Feb 8th before topping
After topping and pruning most of the leaves
Here's today and you can see the new sideshoots growing, these will all produce more peppers than just the single main stalk.
