lamberts potting mix

i was wondering if anyone has used it, and if it works good. it says its organic but i want to know opinions from people who have bought it before. i dont wanna spend the money on shitty soil

also, i bought a 400w hps from htg supply for 120 bucks i was wondering if anyone has had anything bad happen with the system and if it has interference with peoples TV's (the ballast)

no one? i guess ill try it out anyways.
