today i went to home depot in search of 400w HPS lights..once we found them we could not find the correct holder for them since it only went to 250w for hps lights...after talking to an employee and discussing what i am trying to do. he told me it was best if i went to a pet store and bought them from their since they would deffiantly not grow under the bulb i had chosen. i went to a pet store and got the highest watt light they sold it was only 150w but its a sun glo lamp and simulates natural uva rays so the employee at the pet store told me it would work. i bought the light and holder for 25 bucks and now i need to know if i need to return them. if anyone has ne idea if this combo can grow atleast 1 plant let me no. i have pictures but i cannot upload it onto my comp for some reason if you need them to be able to tell let me no and i will do so
