Since upgrading to a new tank, I have found that I may need a new bulb. The thing it, the buld this tank came with is confusing me. Let me explain..
The bulb says the following:
'T8' (I have since found this refers to the tube diameter.)
'15 W' (15 Watt, I get this.)
'Red' >> This is the part that confuses me. I assume this has to do with the spectrum of light it emits, but there is no number (like 6500) just the word 'Red'.
What does the 'Red' on my fluorescent bulb mean exactly? Is this a good light for growing plants? I can tell it looks dim compared to the bulb I had in my previous tank. I *think* I had a daylight bulb in the old tank, but I cannot remember exactly.
My bulb length is 17 inches (18 if you include the metal rods that stick out on the ends) and is the T8 size. If anyone can recommend a good bulb for growing plants in this size, that would be super!
Thank you all!
