well, i started with cfls, got a regular 250 watt HPS and was amazed by the improvements and health of the plants. then i stopped growing because of the landlord and i lent it to a so called friend who ended up stealing it. i was out of money but now i got this and im back in buisness. it feels so good lol. i have never used MH or HPS for veg so it will be cool to see. and my last HPS wasnt digital ballast so im happy this one is. it got upgraded to digital for free.
