I wouldnt use a 600w HPS if its your first grow. Thats a little dangerous without someone who knows what they're doing. I would typically use a 200w HPS for fast growing without the danger. If you get reflectent panels, your plants will grow alot faster, I forget where I saw the ebay light, but it came with a 250wHPS and 2 reflecter panels for 75$. I would suggest that you try to find a 250w HPS and atleast 1 reflecter panel to the side. If one side of the plants arent getting enough ligh, use the panel to reflect the light on to it.
Joel Reviewed by Joel on . FUCK! I'M STUCK!! Hey gang. I'm a first time grower, still in the process of getting my growroom set up and of course, I've hit a snag choosing my lights. I've read that anywhere from 25-50 watts per sq ft. is neccessary to grow good green. I have a closet, 12 ft. sq. total. I was thinking about 3 or 4 plants to start. I'd say a 600w HPS light would be the best bet. On another site I found that a 400w HPS light is more than adequate to grow 4 plants in a 16 sq. ft. room. What should I believe? I want to Rating: 5
