I found my way into the diy bubbleponics thread, looks pretty cheap to get started, what kind of light(s) would I need for a 1 plant setup? My local CL has 600w HPS for $200 (doesnt mention ballast, just says 600w HPS light) , someone else is selling 1000w hortilux bulb and 1000w ballast with cooltube and fan for $250. Are these overkill though? I did see an ad for 250 watt HPS light with new hydrolux bulb,tempered glass lens and some extra bulbs for $160, but it doesnt mention if it has a ballast or not.
