Lighting for a 2x1x1.5 tank and other conditions

[Freakin' Fraud]

I have a got a new 2 x 1 x 1.5 tank and now need help to find out the bare minimum lightings required for my set-up.

Flora planning to include: mosses (taiwan, spiky, weeping)
HC
E tenellus
normal pelia

What would be the minimum amount of lights for these plants to grow healthily?

Also, what would be the optimum temperature to grow these plants?

Is CO2 necessary to grow these plants well? (slow nevermind, but plants must be healthy)

Which is the more important factor -- temperature or CO2?

Thanks in advance

For moss , temperature more important...but again..spiky and taiwan moss do well in relatively warmer waters (relative to Xmass)

E.Tellenus grows much faster with Co2 and plenty of lights.

so , if you are going with Co2 option, I would recommended 55watts. If non-Co, maybe you can go for 36 watts.

Any bros/sis please correct me if I am wrong!

Since you have HC, minimum 55W of light imho. I'd go for 72W personally.

Both temperature and CO2 are important (if you're injecting CO2).

agree. with Hc, minimum must have 55W. I'm having 36W in my small tank of 1.5 feet, my HC doesn't crawl but rather grow tall.
Though it's still pearling under 36W but not crawling, end up not having a covered foreground

pellia tend to grow better in low temperature
