    Grow room size plans: Lighting/Lumens/Space per plant?

    its really not about watts at all, its all about the lumens. watts measure energy and power, lumens measure light output. the plants need the light, not the energy running the light. ever notice how you can get equal wattage bulbs that have a different lumen output? check a regular bulb, like a standard incandescent. you can get 60 watt bulbs that have a 100 lumen output, or you can get a 60 watt bulb with a 250 lumen output. obviously these arent suitable for growing whatsoever, but its the same deal with higher output lights.

    ^^^ they actually have a point people can measure using lumens and or watts its not just all about lumens.

    If it was about that then everyone would get 600w systems because they get the best lumens per watt. (sum1 correct me if im wrong im going by HTG supply systems)

    If i were you and this lighting is the most you can have. I would either reduce the amount of plants and tighten up the space a bit ooorrrr try and go with 1000 watters. I'm sure everything will be fine if you truly have 4500 lumens per sq foot because the best growth is done at 5000 lumens per sq ft. Going by watts 50 watts per plant is what i go by and 200 watts is my max wattage per plant.
