Exactly what I was wondering! I’m using a tank with lid so this will help humidity somewhatI've been looking into this myself. My own plan was possibly to use Epiweb - or Epiweb faced with Hyrgolon sheet - and use a spraybar drip system at the top of the Epiweb, attached to a small pump, to keep it constantly wet.
That said I have no idea if that is sufficient in an open topped tank, or if misting is still required?
If you keep the tank open-top then you could keep e number of regular houseplants in it. The small Ficus sp. could do very well on Epiweb... Some Bromelia sp. and Peperomia sp. also and a couple of undemanding ferns... What you need in relative wet substrate conditions is sufficient light.
But it will significantly limit your choices in tropical bog plants. Read the Emersed Growing forum section to find some inspirations.
Thanks that’s really helpful, I will do some research on these options. would be great if anyone has experience on pros and cons!?There are a number of options Tom, I think traditionally a material called Xaxim made from dried fern was used in panels. You can also get panels made from coco fibres. As I understand these, being natural products, do leach some substances (acids and tannins etc), and do biodegrade over time.
There are now man made alternatives, the main ones I have come across are EpiWeb (Epiweb) which looks to be a thick fibrous material similar in structure to the Xaxim panels which is supposed to be good for plants to root in but don't biodegrade over time, and Hygrolon (EpiWeb - A Better Xaxim!) which appears to be a thinner woven nylon material that is supposed to be very good at wicking and retaining water. As I understand it, both materials can be used together to combined the benefits of each.
I ordered a couple of pieces of each yesterday for my own projects, so I will have a better idea of how they work soon, however I'm sure there must be people on this forum who have used them.
