Im trying to piece together my grow room so I can find the money to pay for supplies. I keep bouncing around concerning how many plants to grow etc. I think being a newbie I should start on the smaller side growing 24 plants and expanding to 36 after learning all the tricks. Should I use 2 600 HPS lights with digital ballast or 2 1000 watt lights. I've already run a 30 amp 220 line to the room. Im struggling with this because our god Jorge Cervantes wrote in the bible that 600 watt lights closer to plants will provide more lumens than 1000 watt lights further away from plants. Each light in my system will be for 12 plants. Everyone I talk to about it says 1000 watts with very little thought. I like the energy savings of the 600 watt vs. the 1000 watt. Living in the desert and having 3 4 hundred dollar electric bills in the summer the 800 watt savings would be nice. Whats most important is yield!!!!!!!!!!!!!!!!! If 1000 watt is the way to go I dont have a problem. Help me with this descision.
