Hi Jay,
Glad you enjoyed the photographs. My set-up is relatively simple, individual species are frown in separate pots with the pots placed in fully covered glass tanks. No pumps, fans, misting system, etc are used. The tanks are filled with shallow layer of water up to 1/2 of the pot height (i.e. the pots are half submersed).
The main problem I am facing is the heat built-up in the tanks when my FL lights (15W to 18W per tank) are switched on (about 6hrs daily only due to minimise the heat built-up). There will be no way of resolving this problem unless I air-condition the room. Well, with this situation, the leaves may melt but new leaves grow too so in general, the plants are still surviving (although I believe they could do much better if the temperature was lower).
The substrate I use is mainly ADA Amazonia, mixed with some peat granule. I mix in some sand and leterite too for species found along the banks of rivers with sandy bed. Root tabs are used as fertiliser.
Regards,
T S Wang
