Hola guys. so up until today grown with MH\HPS in my 170cm*120*60 (5"7*4*2) with 250MH to veg and a 600 watt HPS to flower... So now I see that people vouch for the ViparSpectra which doesnt have Cree leds but Bridgelux's Vero29 which are better from my understanding? and the Mars Hydro uses Cree leds and is less efficient? Now the ViparSpectra 300w model that draws 135w for $80 really seems like a good price per product quality as far as everybody says.. So does the ViparSpectra better than the Mars Hydro that uses Cree leds? Now for a full coverage of a 120cm on 60cm i'd guess I need 2 of these lights, either im going for the mars or vipar which would cost me around $200 not including shipping, so I was thinking if I can get (way) better results with a DIY project for the same or less price. should I go for it? I'm a newbie with electronics so how complicated would that project be? I need it to be done ASAP.. and I have to go with international shipphing also so was thinking about DHL or something... is there any reliable alibaba seller for all electronic parts that I would need? Thanks a lot in advance everybody!
