Yea man. 430 sounds random but the extra lumens couldnt hurt right...is this a grow light or just a regular hps fixture? Like a flood light?
Either way should be good! Just look into maximizing that light. Id flower freshly rooted clones or 12/12 from seed. You probably be able to squeeze a couple more plants in there that way.
I have the fixture... i think im gonna add a 1000 just testing out some midz right now until the 8 ball and ice kush comes in.. first time growing indoors... growing out doors too just letting grow until that time.... You no wat i mean lol here is some pics n ya i no i need to hanh the light this one is doing greatmy lil experi with cfls
the extra 30W is definitely not a fan^^^^the 430 is a great bulb including more blue spectrum for better growth. If you want size then you'd probably wanna start with a 600.
Eight plants, get a 1000 , or atleast a 600 sog style. and get a 250, 400, 600, or 1000 watt light(lights). Dont settle for those 430s. They seem like theyre high.
