Hey no probs.
*
Where did you buy your lights?*
I bought my Quantum boards (aka 'QBs') from an eBay seller (here in the UK), he was an electrician who built the lights to spec (all top quality parts, like Samsung's LM301B top bin LEDs and Meanwell drivers). The lights worked out at £1 per watt (lights were £240 each - when I bought them from him). Both boards are 3000K and happily work in dry or wet conditions. If you are in the US, search for someone your end (it would be a better deal).
So thats 480 Watts of QB (max - the lights are dimmable) in a 1m2 tent (the tent is 2m in height). With 4 plants, I pass the 1gram per watt 'wall'
fyi, QBs are my favourite lights at the moment
*what does the 3000 k mean?*
'K' stands for Kelvin. The light colour is measured in temperature. Basically, the lower the temp the more 'red' the spectrum.
People will say the peak colours are: 2700K (more Red) for flower and 6400K (more Blue) for veg.
3000K is a nice 'middle ground' if you will. It will work fine in veg but works best in flower (I think of it as the 'mixed spectrum' light temperature).
Peace.
