Researching Key Lime Pie at first thought it’s a typo because buds n r are more of a dispo, then i see the word vegetation in wiki.
First time i heard this.
Just like a plant vax, you can trigger a plants sar and immune system at flip to give it memory to be in defense but not ever read cold temps or cold media before 2nd half flower.
To bring out this strain’s eye-catching purple colors, growers may also want to artificially “shock” the plants by exposing them to cold just before flowering occurs.
