i have seen very bushy plants,very compact,their lower leaves i dont think receive much light even in a high light tank,.. so how do you explain that?
eureka!!! That must be the reason that the cabomba in my friends low tech tank ditches its lower foliage when the plant reaches the water surface... i assumed it was because of the very dark conditions nearer substrate level- due to the plants spreading out across the surface.spyder said:master3z said:darren636 said:also diminished light will have the same effect.

I have naked Bacopa stems in a low tech tank. They received plenty of light. It's lack of Co2 that causes the plant to "recycle" itself, in simple terms.

When the leaf is not worth keeping around because it is not cxontributing much/anything to the whole plant, then the plants will sacrifice it.
Self pruning is another way to look at it.
Takes the old leaves and use them as reserves..........to the new growth on top which is closer to the light and closer to the surface where more CO2 is available.
