I'm Jane from Sydney in Australia. After growing a mixed collection, largely our lovely - and tough! - Aussie native spp and hybrids, I am now enraptured by the magical world inside the tiny terrarium in my bedroom. It is a totally low-tech (no fans, auto misters etc) old aquarium lit by two Aqua-One LEDS. Plus light from the window. After running for about 6 months, it houses Angraecum didieri, Macodes petola, Haraella? retrocaella (budding), Bulbophyllum frostii, Mediocalcar decoratum, Lepanthes calodictyon (thriving to my surprise in the current heatwave), Tristadella triglochin, Pleurothallis grobyi, Restrepias, Anoectochilus ?roxburghii, Amesiella philippensis, Epidendrum porpax, Dryadella zebrina, Platystele umbellata (flowers continuously), and a few other non-orchids. Temperature varies widely from around 12 C on winter nights to well over 30 in summer heat. It is partly an experiment to see what will cope with our increasingly extreme climate without expensive and energy consuming technology. The ventilation consists of a couple of holes in the lids plus me blowing on it a couple of times daily . Mist/water by spray bottle 2-3x daily (rainwater with a couple of drops of orchid ferts or seaweed extract).I am a technology idiot but will try to get a photo or two to show the structure. This is basically a false bottom on an old plastic tray with holes to allow water circulation, a couple of inches of water in the bottom, plus an aquarium air stone and aerator to move the water and prevent stagnation. Heating by old aquarium heater if needed, but it was not required last winter. Nice to meet you all!
