Defoliation before flowering

How many leaves should I be taking off before going to 12/12? I don't want to take too many leaves off and I don't want to leave too many on. Any pictures of information for a greater understanding would be appreciated.

Long debated subject. I take leaf anytime throughout the whole grow. If leaf is blocking growth below I remove it.

Some go nuts with it. Just use common sense. Them leave you remove will be replaced pretty quickly. I prob remove a lb of leaf per cycle in my big tent. But looking at them you'd think I don't.

An example of before n after leaf removal. I use floater screens so leaf removal is important for air flow and light penetration.


Cannabis is a super tough plant. You will not stunt growth or harm the plant. If anything your manipulating it to get the most ya can from the plant.
