Basically i'm starting a new grow here because all kids gone now & i have a lot space to myself.I sold old hps light i had back few years ago & i got space to grow more but i just like to have around 6 females growing but i was not sure where to buy a 1000 watt or the 600 watt 2 bulb system.I measured it again yesterday & i can put 6 in this space easy with alot room for them to grow.As it stands i got the space like 6x6 & i have plenty of height so when i spend the $ i was looking for the best lighting system.
