Great news for your and Horace!
I had to put additional lights on my table - they are all timed to come on at different times and for different lengths, trying as much as possible to replicate what it would be like in their natural habitat.
What is really great is that there are forums around like this one, where we can all get advice no matter how trivial we think the problem is.
Good luck - and keep the lights away from the OH!
