you can switch them however you want. do they "label" the switches? maybe they don't want you to change the bulb spots so you don't get confused or something? There's no reason at all that one socket would be any better or worse for different color bulbs than another since the sockets and bulbs are both equal in every way that counts (to the fixture).
thank you. do you think i need to? ...i have 1x 54w HO 12000K daylight and 1x 54w actinic. i was thinking to use 2 daylight or one 12000K and one 67000. its a 55gallon tank with pressurized co2 , ei dosing and root tabs
thanks darkblade. ill listen to you..iv read a lot of your other posts..very helpful..overstocked was a real help too. i was actually thinking of getting another fixture to add to the one i have in case i didnt have enough light...i keep hearing ppl talking about lighting is the most important thing. but i will wait. ill try what i have now with one daylight and one actinic.
does the actinic contribute at all to plant growth??? ....the more i read, the more i am convinced that nobody really knows. i mean, its blue(to me anyway) also the wavelength is in the blue part of the spectrum. i know plants take in blue and red and reflect green. i would assume that the blue actinic would would pretty good.
