Wanted to bump this and add that you can use Highbay lights from Ebay (MH, not HPS as Highbays are rare in HPS), got me a 400W unit for under 50 bucks shipped. Quick trip down to the Hardware store for some sheet metal, chain, s-hooks, and eye-screws and will have myself a 400W MH with reflector for about 60 bucks, just great for the seedling/Veg cabinet/room!! Out with the four 4' flouros after they get a few inches tall and in with the MH!

Learning that you don't have to spend alot, just spend it wisely!!!
HydroDynamics Reviewed by HydroDynamics on . Latewood's 'little guide' to Lighting...No theory, just info! I invite you all to comment and add your $.02 worth, or just learn something. :p This is actually a reply that I made last night on another thread. I thought it might be useful to newer members who are constanly being bombarded with "Grow lamp info" so I am going to post it as a Thread...Perhaps it can be stuck somewhere for reference... :cool: I am building my own lights , now, and will be posting a step by step tutorial of 1000 watt ballast and mogul base w/custom chords.
