Obviously the title explains what I'm asking for... I was wondering if this is possible, and if so, how to make it become a different color. Is it possible to put a chemical in it that would make a color come out, or a die... I have no idea. I would be greatful if someone could respond to this quickly, seeing how my plants are 2 weeks in. FYI It's an outdoor plant, just reg. middies, nothin' special... I just wanted to make it a lil' more vibrant... seems cool. I tried googleing it, but all I got was color changing pipes. Links are fine, or and explantion either or... Thanks in advance... Doesn't matter the color either, red, blue, purple, white (that would be sweet) any color would be sufficient.
