I dont understand this whole twelve hours thing. Is there supposed to be a certain point in the year where there's exactly 12/12 and thats what triggers the buds to grow? (in nature) And also, why wouldn't my plants bud? Do they need to be a certain height or have certain style leaves?

I have seen plants about my height have buds and shit. I dont know what trichomes are either. Im willing to give that thing a shot if sumone could tell me what "panda is", and if sumone can also back up the extra potassium idea.

Thanks.
