I was dealing with anacharis.

Now my question is:

If aquatic plants(anacharis,to be exact) are measured will it make a difference to its average plant growth compared to other anacharis plants?

For example,

I started 6 plants,unfortunately with different start heights because of the reason i just noted.

They were: 18.4 cm,20.1cm,18.6cm,20.1cm,19.3cm,and 18.6cm.

They ended up with:

19.6cm,19.7cm,14.7cm,24.7cm,23.9cm,and 21cm.

So, obviously i couldn't form a conclusion or analysis based on that because others had a higher start height. I decided to do it on average plant growth between measuring periods,i.e day1 to day3, day5 to day7 so it would be fair.

With that in mind ,would higher heights affect its plant growth?

Would a 20 cm plant have a higher avg. plant growth than a 18 cm plant?

This is really crucial to my project and any help would be appreciated, if you need more information

please ask.
