effect of environment on phenotype- hydrangeas (1 Viewer)

[classyandfab]

I've got a bio assessment due in about two weeks with the plan due on monday.
silly question but, if i wanted to use hydrangeas and change the acidity of the soil, would i see the colour change within the two weeks? or would it take a lot longer than that?
or should i just stick to peaplants like everyone else is doing?

thanks

You do require atleast 3 weeks for the color to change

just put 4 to be safe i guess but check with your teacher what the accepted value is
