I'd be weary of those FrescaSol fixtures. I did a lot of research on them and ultimately decided to go standard w/ good air cooling/conditioning. The reason was, u know how water reflects light? Well some people were finding the water between the light and your plants was reflecting A LOT of usable spectrum away from their plants. This was difficult/impossible to see w/ the naked eye but it made a big difference to the plants.
Bottom line is if your not legal, keep it very small, in a basement preferably and DO NOT exhaust hot air directly out of your house. First exhaust into an attic or extra room or crawlspace or something.
