Shelf life isn't really a strain specific thing. If you grow nice tight buds, dry them slow, cure them properly, and keep them in a airtight/light tight container they will last quite a while. I have buds from years ago that will still get you high,, but you usually only have a year or so for full potency. If you don't pay attention to growing quality, and end up with larfy buds they will dry fast and become fragile and fall apart.So, after its cured and placed in storage shelf life?
What makes Blueberry a longer lasting strain?The only strain I know of that is known for a long shelf life is Blueberry. I am sure there are more.
There are also strains that have a short shelf life. My original Trailer Trash Betty has a short shelf life. That is what I have heard anyway LOL. I have never had it last longer then one year. I have had a G-13 Haze for over a year with no major loss of effects. Pretty sure lots will make the 1 year mark with ease. After that you might need to find better ways to store it.
Terpenes make the shelf life thing even worse. I think we've all had great bud that had a THC percentage of 15 or so, and bud that was well above 25 that wasn't as strong. This is called the entourage effect. Terpenes work together with THC, CBD, CBN, and all the other cannabinols making the over all affect stronger.Not sure but I have heard that for years. Could be bullshit. It have something to do with terpene's. D.J.'s strains have a bit different terpene profile then some of the older strains.
Stored at the same level of moisture content, and under the same conditions, in an airtight container, et cetera.... They ought to be the same. Except for the fact that THC (and CBD) does degrade over time, so the strongest strains would naturally retain some potency for a greater length of time than weaker ones, simply because they have more (initial) potency to lose.
