Do blue bulbs give any benefits to plants? i got 2 with my t5ho fixture from fishneedit but i will get different bulbs if they aren't going to help out my plants
thanks

BHead707 said:im thinking of doing one 10k daylight and one actinic for my 20L. very little planted right now but i want some moderate light plants and i hope that will work.
because i looked at a chart and with 2 daylight bulbs i would be over 2watts per gallon seems a little overboard to me.
What a out those plant grow bulbs? They have like a punk hue to it. Personally I live the blue lights though. At night when your relaxing it's nice to watch the fish under the blues.

BHead707 said:ok but what about wattage i dont want to be too high( or is that not an issue).
because the 2 bubs on there now are 24 watt each so i would be at 48 if they are the same wattage that's 2.4 watts per gallon
and i am not interested in dosing co2 either
How big is the tank? The wpg rule is not accurate with t5 HO lights.
BHead707 said:well poo.
its a 20 gallon long,
the fixture is 24'' and two bulbs
Check out the chart I posted above. Do you know how high the tank is and how high the light will be off the top of the tank?
Here is is again:

BHead707 said:or could i just use one bulb and not even have another bulb in the fixture, is that an option or is it not good for the fixture?

Sorry. Aqua Chem knows a lot more about this than I do.
That is incorrect. Depending on the bulb, actinics can pump out anywhere between 40%-60% of the PAR of plant-friendly bulbs. The problem is that this radiation is exclusively in the sub-500 nm range, which comes with issues. There have been laboratory studies done that have found that low wavelength (blue) light can stimulate growth of certain algae species (diatoms, certain cyanobacteria, and rhodophyta algae were used in these studies). So while you can grow plants with actinic light, it isn't optimal, and certainly isn't a loophole you can use to escape algae issues.
And I would be very hesitant about putting T5HOs on a 20 long w/o CO2.
