First off, thanks to Super Duper Coley for some useful starting up info and pictures. Here are all the component parts. I don`t know whether the cable heater is really necessary, but it may help to keep the humidity up. Most light will be daylight, but I may supplement it with one or two 11W Arcpods. We shall see about this, plus the photoperiod. The plastic pots are off Ebay, but there must be plenty of these knocking around people`s houses. The rockwool is from TGM, but available from hydroponic sites off the internet. The propagator itself is from Wilkos and cheap. They are cheaper still off ebay, but I wanted to see one in the flesh, so to speak. Here is the cable going under the gravel. This gives me a rough idea of how many pots will fit in there. Lilaeopsis brasiliensis being added to the rock wool. All I did was cut the rock wool in half, which is how Tropica seem to do it. Here is the final product.....grow damn you. And here is the final shot with L. brasiliensis, HM, HC and Ludwigia arcuata. This set up is really for my 120cm Crypts, Anubias etc when it is broken down. The HM and HC were being acclimatised for under water growth in my bedevilled 60cm, but I have taken them out and am now trying to re acclimatise them. So, all I have to do now is figure out water levels, dosing regimes etc. My fingers are well and truly crossed. Dave.
