I was wondering where I can buy a 400 watt light other then a hydroponic store because I think the only one that was in my town is closed or something? Can I go to Home depot or Wal Mart or something?
I bought mine online. I used High Tech Garden Supply . The store is High Tech Garden Supply. I think Hope Depot has some low wattage HPS, but I don't think Home Depot stocks 400w HPS. The shipping doesn't amount to a whole hell of a lot so I'd say use an online retailer.
