Yes I ordered the Geopod (smaller version) and in came in a couple of days.It comes with two strip lights, an adjustable thermostat with an attached probe, the base (which contains the integrated heating unit) and the lid (which seems a bit light and flimsy!)
I set it up in our attic which has one small loft window so the light is a bit low. I connected up the thermostat in line with the power plug for the base and fed the probe through the lid via one of the two vents. I set up the lights but did not initially switch them on. The first problem I had was getting a high enough temperature. I set it for 28C (for pepper and tomato plants) but struggled to get to more than 22C. I emailed the company and they replied promptly. Turned out I need to have the probe about one inch from the base. There were no instructions supplied with the Geopod (I had to download them) and this was not clear in these instructions! I still struggled a bit to get right up to 28C but had no problems when I switched the lights on as they generate a fair bit of heat.
Apparently the maximum "uplift" you can get with this is 12C above ambient temperature (this is said to be better than conventional heated propagators). This is going to limit its use early in the year in a greenhouse with a power supply (depending of course on what sort of seeds you are trying to germinate). I haven't got that luxury so I have to do this indoors.
Currently I have the lights permanently on and have a good germination of the seeds. They don't look straggly so it's going fine so far.
What I need to do when the seedlings get a bit bigger decide when to switch off the lights and for what period. I have bought a power timer from Argos that I can programme for that purpose. What one would like ideally is lights with a sensor that detects the background light level and gradually adjusts the light to deal with variations of light. I suspect the big commercial growers do this!!
In summary, a bit of a fiddle to set up and get right but so far so good.
