Well there's just too many variables with unknown lighting. Hopefully you'll get at least moderate light being that tank is so small. HC is certainly not an easy plant. It's quite needy of light, ferts, and especially carbon. I've only grown it with co2
... Hopefully you can find the right balance with liquid carbon in lieu of it. It's still a carbon source, but in terms of effectiveness, on a scale of 1 to 10, where co2
is a 10, it's like a 6. So you may have to dose fairly heavy and often relative to the 2g tank, but not too much to cause harm. The tricky part is when you transition from DSM to flooded conditions. Usually, co2
is cranked up to help as HC acclimates to being submerged. After all, HC is one of those plants that prefers emersed conditions and that's why it's so CO2
/carbon needy.. IME, it also needs nitrates. Anyways, good luck and let us know how it turns out.
