I have never used MG for anything....I own/run a landscaping co and I do not use MG or Scotts at all. Scotts is WAY over rated and you are paying for a name imo. Many ppl I know use Scotts, some contractors use them too, but Ive found that there is really NOTHING special at all with their products and they are very $$$ too. And the fact that they bought out Gavita, Eye Hortilux lamps, General Hydroponics, Botanicare and Foxfarm. They are really a nasty company/corporation with many substandard business practices. I try to do buisness with locally owned companies if they are price competitive, which most of the time they are or very close. My partner does the horticulture side as she went to college for that reason so I usually just let her do her own thing. Sry didn't mean to get on rant and I hope GH doesn't let them change their products or practices, either way we just stay away from them. LONG DAY, got a freakin ticket for using my phone while driving but I was using the GPS not the phone he didn't care. So I will see him in court, if he shows up which half the time they don't and there where some other things I can produce in defence.
