        One word on halides; They may be more expensive to set up, but they are far brighter than tubes, illuminate a larger growing area, and are much cheaper to run in the long run in terms of the light ouput you get/ unit of electricity consumed.. also an advantage for taller trees, or anything over 10 " tall..

        Yes, heating is a problem with basically any reef set-up in the summer in a non-ACed house, and halides make it worse.
