I just got a new virtual sun 10x10x8 grow tent that I'm going to set up as my flowering room. It's going to be out in my garage and it doesn't get hot where I live even in the summer. (a hot day is 75-80). I'm trying to decide on running either 4 1000 watt or 6 600 watt lights. I'm running one 6" inline fan for ventilation. My friend at the local grw shop will sell me 6 600 watt lights with "batwing" type reflectors or 4 1000's with cool tubes+ reflectors for roughly th same price, with the 1000's being slightly more expensive. Both setups are all digital/switchable/dimable ballasts. Please help with any advice or comments u have as I'm trying to get this going soon because the girls in my veg room are getting huge. Thank in advance
