HPS question

[The9rideNblack]

will a 400 watt HPS system work for both the vegetative stage and the flowering stage? if not what should i consider getting?

you dont need to get anything else that will work fine, remeber as the plants are young they burn easy and to much light its good for them so keep the light alittle farther away than normal. as it gets bigger and stronger you can move it closer

all i use is a HPS and ive had no problems
