Re: Doesn't a t-test work here?

ideal to
ignore plant variations, but I think for my purposes it should be
okay.  These plants are not like humans, they are all clones of each
other.  All grown from the same batch of seeds.  All planted in the
same soil, watered at the same time, exposed to the same amount of
light, etc. etc.  I realize there will always some differences, even
in clones, but these should be minor.

As a biologist, I can say that with few exceptions, plants raised from
different seeds are by definition, not clones. Plants raised by seed
even from the result of cross fertilisation from the same two parents
can vary considerably, depending upon how pure bred the parents are.
Even self-fertilisation results in some variation between seeds due to
the meiotic process. A clone is an organism with identical genetic
makeup to another and is normally produced by what is called
"vegetative" reproduction, where for example cuttings are struck from
the same plant.
