Bro, i'm playing with electrical equipment for more than 25 years already, this is nothing, just some pieces of metal and components which i did not manufactured myself anyway

What about GN HS1 components - it's casing simply did not fit in my box with my addon, but it's components are top quality and this is why it is pricey. Superb quality driver, copper base LED matrix with carbon plated cooling, quality assembly and total unique optics - GN did great work with introducing of their diffusers - it alone is worth a big part of unit's price. Not regreting of buying at all and it alone is capable to give enough light to one plant and i was using it alone till plant grew a bit, to not scare a plant

I did not copied HS1, bought completely different spectrums, just to have very wide range, even skyblue and orange LEDs are there. I believe in theory that it's quantity and richness, not few wavelengts. That is why HPS still rules in big grows
Ever thought about regulating plant height by adding too much light? Well. this is the case

I'm testing this theory right now, but results will be clear minimum in 10 days.
Anyway, i'm thinking about diary here on AFN, maybe it will be interesting for someone

It is not good to do so much input into thread which is not connected by mean.
