My S. Wrigleyana doesn't have the nice red coloration. *Does it need lots of light to obtain it? *Mine is only green and white. *[img]http://www.**********.com/iB_html/non-cgi/emoticons/confused.gif[/img] *It looks more like the one pictured in the PFT store Wrig pic. *Any suggestions on how to improve colouration?
