I would shoot for the 600watt. They have the highest amount of light output per watt than either the larger or smaller sizes (i.e.: 250, 400, 1000, etc.). For a new grower, you could expect up to about .5g per watt in good conditions, maybe 2-300g for the 600.
gainesvillegreen Reviewed by gainesvillegreen on . Planning My Grow Room. Im getting this 250 watt hps system that comes with a mh bulb and hps bulb off ebay, I was reading the description and it said that this would be best used in a 3 x 3 area. I have some left over drywall from remodeling my bedroom, I was thinking of building a 3 x 3 box and painting the inside of it white. Im planning if I can to have a couple small plant's, im gonna split the box so it has a veg room and a flower room leaving 18 inches of width, and 3ft for height. Would I get anything good Rating: 5
