also can someone answer, how many different lights will i need? i've read so much over the last 2 weeks but i'm still unsure. let's say i start from a clone, so right there we can say that i won't need a different light to get a seed to sprout...? really if i start from a clone all i would need would be a 250w or so and make it so that it can move up and down...? that light would get me through veg and flowering stages?
