Basic soldering is required. Nothing super difficult.
I got mine from RapidLED.
It was difficult to understand what I needed, but Planted tank is much easier than a Coral tank - Coral tanks have a mix between Blue and white LED
's, and then a few Red as well, which means you need a power supply that can handle it. Because LED
's of different color typically draw/use different amounts of Current/voltage.
My setup has 12 XP-G R5, which is a nice, clean white, but not blue at all. Plant growth has been great, and 34 watts of LED
's grossly overpowered the existing 108 watts of T5HO.
You need to have a basic understanding of electrical systems - Voltage, Current, etc.
RapidLED was SUPER helpful with my questions. I felt compelled to buy from them because of all their help - it also helps that they're the cheapest source I could find!
