If the intended purpose is root growth, leave them on 24/7.

Also - "Ezi-root gel", and "Auxinone".

Hi Ray, thanks so now I've got the lights and the heating pad set up. Here's the latest update, with pictures.

First of all I was a bit worried about the heating pad, because I don't have a thermostat or temperature control with the heating pad, and I heard they can get too hot if they're on day and night. Well, it's been on for almost two days now and to my surprise it's not that hot as I expected it. It feels warm to the touch and if I touch the bottom of the "green house", the green colored thing it's not cold, it's more like luke warm. OK, so I tried using the thermometer. I have one that just measures the temperature in the living room in general. So my living room was at 19,6C (67,28F) this morning. So I placed the thermometer where the heating pad is, it's 4 hours later and it reads 20,2C (68,36F). That's not very much of a difference is it?

Anyway I have this little "green house" thing that I plant seeds in the spring in, like tomatoes etc. So I have the lid but at the moment I'm not using the lid. Should I place the Schilleriana and the Hieroglyphica with lid on top? I'm only worried about mould in this case.

The heating pad is small, smaller than the "green house" thing, but I got the smallest size because my "green house" thing is first of all small, and because the other heating pads were so large in size it would have been larger than the "green house" thing.

Another question: Is the placement of the lamp good? As you can see I've got a number of other orchids there. I've got an Oncidium, 3 Brassias, the Miltoniaopsis, a Cambria hybrid, a Paphiopedilum Pinocchio in the background. A Paphiopedilum Mauidea and a Callosum, oh and a Phalaenopsis Liodoro. (These are all by the west side window).

I've also attached some pictures of (in total all my orchids :biggrin: ) my regular Phalaenopsis. I've got a three on the window sill east. As it is fall now, days have less daylight, and even in daylight it's kind of dark (thick clouds). But yeah that's what it's like here.
