Many of you might have seen Riparium Supply shop 9http://ripariumsupply.com/store.html), where he sells Hanging planters, like this one: The idea is fantastic, as allow you to have emmersed plants on a normal tank if you so wish, just check what can be done on this blog (http://hydrophytesblog.com). It took me a while to track who in the UK would sell hanging boxes, and after a while I managed to track a company that would do it, actually they may be the ones that supply Riparium, as this is made on the USA. Check them out on http://www.blisshome.co.uk/product.asp?product=966. I ordered 10 units, it came at Â£36 including posting. They are slighly bigger, but will do the job, and as they have larger holes on the front it is perfect to use with clayballs, as nutrients will flow in and out thru the roots. This is what I have: I will set up two or three on my tank and then see what happens, but at least we have a way to get the kit in the UK without having to import it ourselves.
