Harvest now before you turn amber.
My wife and I recently completed a grow we did to help answer the question ‘Does Amber give couch lock?’
We harvested a portion of each plant with little or no amber and the rest when amberitius had set in. Our results (so far and unofficial) show that Amber gives you 2 things, couch lock and possible phantom pain. The heavier the couch lock, the greater the phantom pain. The plant with little or no amber has no couch lock at all, Sativa or Indica.
