Does anyone have experience with double ended fixtures, specifically the Gavita 1000 or better yet their 600/750 watt version, I have 7ft cellings. Is my 7' limitation enough to allow me to use the 1000 watt double ended?
You have 7' ceiling height. Are you taking into account space between ceiling and fixture, canopy distance needed, pot height from floor? So realistically you have around 5' of space.
It's gonna be tricky with that soace, but can be done.
