100% EcoEarth is not a great substrate for plants. In it's place would use ABG soil. Around the plant pots, can use EcoEarth. Cypress mulch is an impaction risk (and could be toxic if exposed to chemicals). Sphagnum moss sold for vivariums should be OK if you feed in bowls and insects never escape. Do be aware that if a frog eats it, there is an impaction risk. Good luck!
