I count from first day of 12/12. But I use that as a estimate and count out 9 weeks. From there ill heck the trichs and overall shape for chopping.So seriously how do all you count day of flower? From switch to 12/12 or when shows flowers? Don't really matter I go by trics anyways. But I want to know. Everyone is different on their ways. Myself I count when I notice flowers but I'm thinking should start from flowers. Reason I come to this conclusion is my girls look farther along then 43 days.
