Its time for bulb basics! My old High Intensity Discharge Bulb video, originally filmed in 2012. Read full description for a link to cheap bulbs! LEDs, Plasma Lights and Fluorescents are getting more popular but nothing hits that perfect spectrum yet quite like HID bulbs...both metal halide and high pressure sodium... so they are still used at some point in the growing cycle by the large majority of Marijuana growers (as of 2015). Today on Lex's World we'll compare these two bulbs, whether they should be used for Vegetative or Flowering phases, how much they cost and a quick safety tip. We'll also talk about the rarely discussed but valuable conversion Metal Halide bulbs. Do NOT pay $60-$100 per HID bulb at a Hydroponics store. I always stock inexpensive HID bulbs at my Amazon Store, plus shopping there helps me make more episodes: https://www.amazon.com/shop/influencer-945853a8 My Facebook: http://www.facebook.com/lexsworld My Twitter: http://www.twitter.com/lexsworld Have a pressing question for me?
