hello tomthehippie yeah them lights are good im using a 200w envirolite blue spectrum for vegatation and soon i will be changing to the red spectrum for flowering,it will definatly give you good bud but the yeild depends on ya room remember the more ya veg a plant the bigger it gets and will give out more budding points when you switch over to flowering but i would veg up untill the plant gets to half the room hieght because when ya flower they will stretch towards the light and you dont wanna run out of room that will just result in unfinshed bud (not nice)

personly i think there is nothing wrong with our lighting method
it is cheap no need for a ballast and dont produce much heat
what more could we ask for for the price
