Total beginner on Orchids.

[demosthones]

I thought I'd introduce myself. I've been doing some indoor gardening for a few months now for vegetables, herbs, etc.

I'd really like to start growing some Orchids. I would like to plumb the depths (or explore the heights) of the indoor Orchid growing hobby.

I will search on this site, but could someone guide me towards a good beginners tutorial on growing Orchids? What is an easy variety to start with (and where can I get some rarer varieties once I know I'm not going to kill them.)

Here's my equipment. At the moment I have a 400 watt High Pressure Sodium grow light (puts out 55,000 lumens mainly at the lower end of the kelvin scale). My grow room temperatures this time of year range between 58 F at night to about 78 during the day. Will I need to warm the night time temps up with a space heater?

My RH runs around 50%.

Will this grow room work for Orchids? If not what should I be shooting for? I'm hoping to set up a grow tent just for Orchids in the next few months, but I want to experiment on the periphery of my current grow room.

Well I have a thousand more questions, but I've asked more than enough for one post.
