Echinodorus bleheri- from 10 to 30

I have a 15cm (6") tall Echinodorus bleheri (Amazon sword)My question is, how long will it take for the sword to reach a size of 30cm (12")?
Thx for all the feedback beforehand.

Welcome to the forum!
To your question:
It all depends on the conditions you grow the plant in.
If you have a lot of light, CO2 and fertilisers, you can have a much bigger plant (bigger than 30 cm high) in say, 1-2 months. If you have less of everthing, it can take many months.

P.S. E. bleherae (note the spelling) has been synonymised with E. grisebachii (as well as E. amazonicus and E. parviflorus).

I just have a nutrient rich substrate + tablets, liquid fertiliser and somewhere between 1.5 to 2 wpg of Juwel T5 (no co2), so I'm guessing it would take somewhere between 4 to 8 months.

P.S. If the sword and a few bunches of cryptocorynes are the only plants in a 50 gallon that has little surface movement and a medium stocking density, would there be enough co2 for them?
