Which Strain Should You Choose?
For deeper relaxation
Granddaddy Purple

For creativity
Blue Dream
Blue Dream makes more sense when you want your head to stay active. Creativity is one of its standout reported effects, giving it a much more daytime-friendly personality than Granddaddy Purple.
For grape flavor
Granddaddy Purple
GDP is the obvious choice if you want grape, berry, and sweet notes. Its fruit-forward aroma and flavor are some of the strain's most recognizable characteristics.

For nighttime use
Granddaddy Purple
Granddaddy Purple's combination of relaxation and sleepiness makes it much more naturally suited to late-evening sessions when staying productive is no longer the goal.
For daytime versatility
