Oh nobody wants to give a little imput for the topic? Really no one wanna put there too cents in this one! Everyone wants to tell me" why did u buy a kind " instead of a Chinese light that should really be lighting my xmas tree! egotistical fucks! That's why I just followed this shit in the past and watched mostly tards telling new growers oh watch your ppm here and runoff too here! Really? most off the time you have no knowledge of all factors involved! And these fucking Chinese lights! Come on man are u gonna spend $ on a light that will never ever get fixed or replaced if it goes down ! during a grow! your Chinese lights are glamorous veg lights! So go fuck around with china and I will buy a heliospectra! half way there! Let me guess your gonna bash the heliospectra I want right? In this period of LED development do you really think they are gonna tell you all of there Research and development of there own technology!? Pick ,Pick, Pick<nitpick! Don't worry your cousin chester the garbage man will recycle those knockoffs at the dump!!!
