Zoa growth question

[dano83]

I am thinking of making some 6" square coral disks out of aragonite/portland cement. These would be 36 sq. inches of course. If I grew out zoas to where they covered the entire piece and then took 18 one inch frags out of it, how long do you think it would take for them to regrow completely before it could be fragged again.

This is hypothetical of course and assuming optimal light/water conditions. Also, I guess fragging it like a checkerboard would help it grow back faster??

I think that round disks will work better but just for the sake of math, I am asking about square disks for this.

Depends on the zoas... Different types grow faster than others.

Well, the math would be the same if you use the 36 square inches block or many of those round discs to grow the zoas in that same area, as you already know.

To cut the 36 square inches blocks you would need healing time for them to be ready, while if you place them to grow on small discs you'll have them ready right after the growth.

It is basically impossible to predict the answer because there are so many variables in question between the two methods you mentioned.
Besides all the "optimal conditions" we can provide to the zoas to grow there is also the species' ability to do so. Then, the individuals' probability to reproduce/grow.

The more polyps per frag the faster are their abilities to fight bacterial infection, to actually heal from the cuts and to beginning the growth process.

I would say that would be great if you would start gluing them to the disks and have fun with the project!! That way time goes faster!!
