the 250WT will give plenty of light in a 4'sq-ft area(62.5WTs)....bonbon
bonbon Reviewed by bonbon on . Light Wattage? I have a question about lighting. I was most likely going to going to go with a HPS lamp setup. I am probably going to only have 1 to 3 plants at a time in a small grow area. I was originally going to go with a 250 W lamp, but the more I read about it I thought maybe a 400 W would be worth the extra cost. If the grow area would be around 2 x 2 at most, would the 250 be good enough or would I need to spring for the 400. Also do most lighting stores carry these types of lights and setups for Rating: 5
