So just like the title says, im upgrading this month and i need some advice. Right now i have a 1000 w hps in a 4x4 tent with a 4 foot 6 bulb t5 for veg. I just bought a new 4x8 tent and I need to increase my footprint from my lights. So the question is, should i buy a 6 foot light mover for the 1000 watt light that i already have for 170 dollars brand new(very nice and sturdy model), or should I add a 600 watt hps to the mix(also around 170 brand new with a digital ballast and hps and mh bulbs and cooltube)? Do light movers really work that well? or would the 1000 not be enough light to cover the area? Also if i added the 600 would i need to add more ventilation? I have a 400 cfm hydrofarm fan and a booster fan for my intake. Thanks in advance
