i just bought a1000 watt light. not sure on how to use it with my 3 old lights which are 600 watt.i still plan on using 2 of the old ones with the new one.i am growing with 12 gh waterfarm buckets i am adding four more. kind of new to indoor growing

If you're new to indoor growing, why did have 3 6oo watt grow lights...and why then buy a 1000 watt light? And you're growing hydro for your first indoor grow? Be careful. you should have a few soil grows under your belt before you switch to hydro
