I am 4 weeks into flowering in a ebbflow hydrosystem in my 3.5ft x3.5ft grow tent in my closet. I had been using a 400 watt with an enclosed hood where the air was sucked out into the attic. It has a magnetic ballast. I just bought a 600 watt digital ballast with 600 watt bulbs and a really big air cooled hood with the hot air being sucked out too. What is the smallest height u would recommend me it being hung above my plants, so the get the most light without burning them. Thanks
