Just switched out my 2x150MH for a 6bulb tek unit today. So far I like it
Nice and light, so very little heat being thrown off. The colours are nice and I like that I can fine tune it. The only thing after a few hours that I don't like is that I miss the MH shimmer
Since it's only one day I can't be positive if I made the right decision (I was also thinking of changing into 2x250MH) but I guess time will tell eh?
