More than likely all things considered. Just try to keep an even canopy, and control the heat. It's also much more convenient with a single hood then positioning all kinds of CFL's around the plant. That being said, how many plants do you plan on flowering? A single 150 hps is probably good for one decent sized plant, two smaller plants... When i first started I just used 2 x 150 HPS (DIY remotely ballasted security lights) under a single hood and could flower 4 3 gallon plants in a 2'x2' area with good success.
