For 4 plants you won't need a 5x6 area, the light will probably only need to cover an area of 2x2 (1sq ft per plant) so a 250 watt hps will suffice or a 400 watter if you want to go a little over the top but IMO either a 600 or 1000 would be complete overkill for 4 plants. For an extra $50 i'd definately get the cool tube, your heat will be a lot easier to manage with it.

Good luck.
hudson88 Reviewed by hudson88 on . Which light for this room????????? Ok so the room is around 5x6 ...Hydroponic setup,4 plants are going to be in the room(well closet).This is only a flowering room. I am trying to decide between a 600w or 1000w HPS. Now im not to sure if ventilating the heat will be a big problem or not,im thinking that it wont be,but lets keep that in mind aswell. So my question's Will i save alot more power and energy usage with the 600 opposed to 1000? Will i have alot easier time keeping the heat down in the room(and venting it Rating: 5
