Updated spec v

I just picked up my new spec v, I got the new version with the brighter fixture and honeycomb instead of frosted back glass.

My main question is this; what plants can I grow with this light? What are the limits of this fixture? (I am planning on running co2) I can't seem to find much info on the new lighting but will say I am impressed with how bright it is.

you can grow any plant. They will survive, and they will grow. How fast? I don't know. your light fixture will be somewhere around low/medium rating. People grow high light plants in low lights like hairgrass. They will just grow super slow.

I have the older Spec V and use the original stock light, no ferts, no Co2. I have grown java fern, anubias, hygro compact and I forget what the grassy plant is. So if the new lights are stronger and you add Co2, I'd think you could expand to more varieties. Here's a pic

That's an awesome setup SueD! I'm hoping to accomplish something lush like that

Thanks. I like no muss, no fuss tanks - I'm lazy. My other Spec V has an older Fugeray on it. The moss in here gets out of control and I have to keep trimming just to see the fish. The crypts run wild too. No ferts, no CO2.

I have the older Spec V and the light was too dim for my purposes. My coworker, however, has the newer Spec with the upgraded light (photos attached) and it's super bright comparatively. So bright that it caused him a lot of algae issues which he resolved by adding those floaters.*

I don't know PAR values and whatnot but I think it might even be able to grow some of the more demanding carpeting plants.


*Fyi for the photo, the floaters are real live plants and there's Christmas moss in there too but that big green plant is plastic.

My updated spec v grew out a full DHG carpet in about 5 weeks.. Dosing excel/flourish and some root tabs.
The new stock lights are great, I don't think you'll be very limited.

That's the info I'm looking for, I'm wanting some sort of lawn in this tank. I'm undecided on dhg, hc, or glosso.

So you arent using co2 at all and just using excel as a carbon source?

Right on. Yeah the dhg has done almost too well. I'm in the process of removing/thinning it out some to allow for some new growth. And yes that's right, just excel, no co2 injection.

Thank you for posting this, jimmeh lee! This is exactly what I've been looking for! My new spec v just arrived today and I've been wondering/worrying about what plants to buy that will grow under the new stock lighting. I plan to dose excel/flourish too. Your post and pics solved that problem for me!

Have you had any problems will algae, related to the lighting? How often and how much flourish and excel do you dose? It's been awhile since those pics, what does your spec look like now?
