Is there a difference in growth with Specialty bulbs? Right now im using regular Homedepot bulbs. Sylvanya 250 mh and Sylvanya 400 hps. They are nothing special, but they cost less than 20 bucks each. That being said, is it worth the money to buy a bulb like a Sunmaster, Eye Hortilux, or Agro -lite? All of these bulb are in the 100 range, are my plants going to grow any better? you input will be helpful.
