For instance ..im on a tiny budget..i search and searched the net..and bought a 400w HPS 'SON T PLUS' from Philips... but coz it was so cheap i cant help doubting whether or not is has all of the correct wavelengths!! can anyone please 'shed some light' on the matter :D what is your first choice lamp??
