Such a fixture and bulbs isn't going to come cheep, and it's not going to be cheep to operate. Note too that you are almost in the same watt range as MH's would be. That is 2 or 3, 250w MH bulbs, for 500 to 750 watts.
I'm not trying to push MH on you, if you like T5s. There are advantages and disadvantages both ways. I simpley want to point out that good light doesn't come cheep. |
Wow....I only have about $600 to spend. Guess I might have to start thinking of going with the 90g again.
