Looking for a little help. Getting ready to buy a 400 watt unit. Would like some advice on which brands to look at and which one to stay away from. Also, are the switchable units reliable or is it better to just use conversion bulbs?
dont know much about difif brands but you want hps for flowering (IMO the most important part) and mh or flouro's for vegging and cloning. i also hear you can vegg with hps but have never done it. i vegg with flouro's and flower with hps. hps transformers that have multiple taps can be operated on different voltages. i run my hps on 240v with #10 wire, and the wire never gets warm.
defenitly go for a switchable ballast ... i dont give a shi* what anyone else says, conversion is totaly more expencive to replace every grow then to use 2 bulbs for 2 crops.. besides ballast need to be rebuilt or replaced to insure that you are getting your hours to bulbs. things dont last forever, if some one told you, some thing can last forever, their wrong... expect to invest on the largest wattage that you can save up for or affford. i reaped wealthy on a 1000w hps ballast, im buying an 2nd 1000w switchable ballast in 2 weeks. im expecting an serious increase on results and outcome
