Question Is this bulb suitable for planted tanks? (if someone will be so kind to answer......)

EDIT2: Adding onto the thread again.
I finally found a 33 inch t5ho bulb, but it's 12000k. Is it suitable for my plants? I'm only growing moss, dwarf sag, and low-light plants.

EDIT: Just adding onto my old thread, since it's not a huge question... I can't seem to find 33 inch T5HO bulbs anywhere online! Not on amazon or petco or Dr. Foster&Smith, not even in google search, it seems. I'm looking for one around 5000k~7000k, closer to a natural daylight color. Does anyone know off the top of their head where I can find this? It looks like 33 inch bulbs are quite rare.

Since I have an AquaticLife t5ho fixture, do I need to AquaticLife bulbs?

Or can any t5ho brand of bulb fit into any t5ho fixture?

Any brand will do as long as youre going with the same wattage and making sure it is a high output t5 bulb.

I had the same problem with finding 20" bulbs for my odyssea light. I ended up just buying them from aquatraders where I got the light.

Try Petmountian I just bought 2 33" 6700k bulbs for 29.00 shipped they will be for a 36" fixture but if you look they are 33" bulbs. Hope this helps. http://www.petmountain.com/category/...-ho-bulbs.html

Crap sorry they are 34" bulbs

Dang, everything's 34 inch .... so close yet so far.

I finally found a 33 inch t5ho bulb, but it's 12000k. Is it suitable for my plants? I'm only growing moss, dwarf sag, and low-light plants.

Here's what I do when I come across an unknown bulb. I look for the spectral distribution of the bulb in question and if I find it I compare it to the known chlorophyll absorption charts found on the web. Since a spectral distribution chart is provided the question you have asked can be answered.

The thing is, I'm not particularly looking for the BEST bulb out there for plants, because so far, I can't find any other 33 inch T5HO bulb for sale anywhere. I'm just wondering if this bulb will be SUFFICIENT for my low-light plants, because I don't have enough experience to determine how much of an impact the difference in spectral distribution will affect my particular plants, and if the average impact on the plants is worthwhile, or if it's completely and utterly useless and I should keep looking/waiting.

Pretty bummed that 33 inch bulbs are actually so rare though.

The question you've asked is not about the best bulb. Just if this bulb will work. You could go a step further by looking at other known bulbs that work and comparing both spectrums. For instance Geismanns Midday bulb.

Give yourself some credit and take an educated guess. I won't tell you what I think because you won't learn anything that way.

I did compare before I even posted this thread, and my "educated" (but not) guess was that it will work for moss and my other plants.

It's not like I can find any other 33 inch bulb anyway, though. But if it's a complete waste of time, and all my plants will end up dying or something, I won't go driving an hour and 20 minutes to Marinedepot and back to pick up a useless bulb. Alright?

And then I asked on this thread, so that I can get correct experienced advice from veteran aquarists and skip a potential failure that I can't afford. College students aren't exactly the wealthiest people out there to just throw around $20's and $30's and wasted time and gas money.

Now, what do you think?

Are you certain this bulb is 33 inches? I see it listed as

12000K is really not going to even look good on the plants. They will probably grow under that lighting, but obviously not very well.
