In that case, the light makes the difference.
If you decide to go for the HPS1000, I STRONGLY recommend a good exhaust fan connected to an air-cooled hood. Aim for a 200+ cfm fan!
It's good that you vegged extra time if you are only growing 4 plants under a big light in that space. I'd personally grow 36 small plants SOG on a 4x4 runoff tray in that space. You can set it up in many configurations, depending on what STYLE of hydro you prefer. But longer veg=fewer, larger plants to fill the same space. Try to train them as flat as possible as you are flowering them, and then let the buds grow up straight with no more training after the 'stretch' period is over (2-3 weeks in).
stinkyattic Reviewed by stinkyattic 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
