hello,

I have 2 tanks with water lettuce in, the main tank 180L also has co2 at a rate of 1bubble per5 seconds. This tanks water lettuce is nice and big (the size of your phone), and gets culled every month as it’s covers the whole tank.

I had put some of the smaller off shoots (50p size) into another tank 60L no c02, and they have stayed small but also multiplied small as if it’s a nano version, but it is from the same as the other tank.

Is this due to less co2? The water temp is the same at 22 degrees, the smaller one is slightly softer (although both active soil and ro water).

Not CO2 as they are in contact with air ( plenty CO2) but they are responsive to ferts and light and sensitive towards flow in my opinion.
