Tiger lotus question

[Jeff1192]

So I've had my pressurized CO2 running for a few weeks now and I'm getting great growth with pretty much everything. However, my tiger lotus isn't getting that big. It was in my tank before CO2 so it was pretty small. I'm still getting new leaves growing, and they're quite red but the leaves aren't that big. Is this a type of plant that would benefit from root tabs? Any other ideas.

Thanks,

Jeff

Oh yeah, root tabs!  Tiger lotus have a HUGE root system - I had a mother plant in a 75g (4') tank and the roots reached both sides of the tank.  It will grow eventually. We got our mother plant as a bulb with one teeny leaf from Big Als; it took about a year but it did eventually get huge, flower, and produce lots of plantelets.  It thrived in all conditions, with or without CO2, highlight or medium light.  I don't find they really respond to CO2... in my experience they only explode with growth if their leaves are allowed to hit surface.
