What type of lighting to put on a vert. ten, I have lots of 18 inch lights but there to big for the top. I was going to make a vertical ten for a temporary setup for a pair of imitator I am getting next weekend, but could I just keep them in a ten instead of a vertical ten until november when I am going to get them a 30 extra high. And how long do you wait between the first hatch of hydei and using them to setup new cultures.
