The spectrum is fantastic for growing plants. I can vary that depending on what bulb I use as well. I can even get retrofit MH
bulbs for it if I have to but they cost about $100aus each. The temp is unknown as it is irrelevant in hydroponics. If I had to guess though I would put it around 5500kelvin. Very orange light but as I said I can offset that with the right bulb & a flourecent fitting. (which would change the k
I think I will mount it over my 3ft propagating tank with no fish & see how the plants go for the next month or so. I'm still in the early planning stages for the 6x2x2 so I have plenty of time to find out if it's good for the plants, I'm betting it is. I just want to find a way of testing the effect it has on the fish without actually having to hang it over one of my other tanks. They are all well established & I don't want to mess with them.
I guess I will be the groundbreaker. You never know, maybe I'm going to make the next big leap in aquarium plant lighting! I will post the results of my tests. Sorry no pics. I already know that you can't take photos under one of these lights.
