Are these lights suitable for 2 Auto's in a stealth grow

its a CFL, so just remember that the actual light intensity diminishes very very quickly as the distance between the bulb and its target are increased. you may need more than 1

they will do but would you rather be using a 400 or 600 hps instead of 600 watts of cfl? the heat given off those will be close to a 400 hps anyway and you will be getting more bang for your buck with the hps,

get a 250watt hps if your going to go that big on cfl, or gets lots of smaller 50watt ones, better coverage
