I have serval philos, most bush, my favirote is a varigated heart leaf that is thriving. i think the t5 grow lights make all the difference in the world. i rescued it from a bach mens, and took it out of its pot, repotted it twice and gave it feeding of mericle grow fertlizer now its growing vines like a weed. i plan on ripping it up a little at the roots to train on a moss pole later on this summer. its leaves are as big as or nearly as big as my hand in some cases.
