Kinda up to you.

When the trichomes turn cloudy your at peak THC (from what I gather). As they turn amber, they convert from THC to ???(another three letter acronym)

From what I understand. This second chemical is thought to make the high last longer, but NOT actually get you high on it's own.

Some will answer ZERO percent amber, and cut now. Some will answer 20% amber, cut in a few days. Plus a small percentage will even say 50% amber.

Question is (to me anyway),... Have you been flushing?
