There's one on amazon or ebay (memory's shite this morning) for $325 after shipping. It's not Gavita, But it's apparently American made and ships from a green state.
It's cost roughly matches the 4 pack of cobs with shipping lol.
Has anyone in here actually completed a grow with a LEP? If so, What was the yield in comparison to your regular lighting?
I know of one who's used LEP - but it's not really a fair comparison, as he was a hydro master, and had loads of other lights (including HPS, LED) and used the gravita as supplemental (but over one plant).
