"Mushrooms" is a UV (ultraviolet) blacklight fluorescent and glow-in-the-dark phosphorescent
t-shirt / hoodie print, made from the original psychedelic spiritual visionary fantasy
fine art backdrop painting by Symeon Nostrakis, and depicting a Magic Landsape:
An Endless Forest Field of Amanita Muscaria (Fly Agaric) Psychotropic Mushrooms seen in perspective, which stands as a Symbol of the Earth Element in a much larger Composition.
If you don't have a UV black-light, the t-shirt/hoodie will still glow in the dark and of course be visible in normal light.
For better glow-in-the-dark results place t-shirt/hoodie near a bright light source and allow at least 30 minutes for charging.
The brighter the light and the more time the t-shirt/hoodie is exposed to it, the more energy it will absorb and the more it will glow.
Additionally, the darker the room when you switch off the lights, the more pronounced the night glow effect will appear.
A black light source will charge the t-shirt/hoodie better and will make it glow more than a normal light source would.
Alternatively, you can use fluorescent lighting for charging (FT tubes or small CFL economy lamps).
Old incandescent lamps cannot provide sufficient charging as they do not emit UV light.
