Your best bet is to look for a Pothos plant. They don't need much light, hard to kill and safe for your T.
Find a smaller plant.
Remove it from the pot and wash the soil off the roots. Also a good idea to go ahead and clean the whole plant.
Replant it in something a little bigger and use your Eco-Earth. You can place a fertilizer broke in half in the bottom of the pot.
I'll see if I can dig up a good video for you.
