BatGuanoanswered grow question 4 years ago Dear Angypangy,
If you can take the magnified (50x or more) pictures of the trichome, you can guess the best harvest time for your plants.
Secondly, please don't cut the top of each branch. If the top is ready, probably the bottom is ready, too. Just make sure that you cut off the whole branch and hang it upside-down. You can leave the rest of the branches to grow a bit more. Check my AK47 Diary for harvesting pictures.
P.S.: When the harvest window opens, you will get different effects from the same plant depending on when you harvest. You can check "trichome-method" on many websites to decide on what. In short, if you harvest early, you will have more euphoric effects (with less THC) and if you wait a bit more you will get max THC (all milky trichomes) without any euphoria. When you harvest at the end of harvest window (amber trichomes) this will mean that some of the THC are turning into CBD which will get you more relaxing-anti anxiety effects (by an exchange of some THC.)
Suggestion: As this is your first growth, try to harvest the plant at different times during this Harvest Window and choose which one you liked most and then you can decide by yourself. (Check on my AK47 Glorious growth. As my friend loves more energetic-euphoric effect, I harvest this strain early. If I waited a bit more, probably I would get 20gr more but it is your preference :)
Hope this helps!
