i have actually changed the method of my experiment.

I have changed it to have 4 testing plants (all the same type of seed used)

test plant 1 will be given 10ml of water every day.

test plant 2 will be given 10 ml of chamomile tea (cold) every day

test plant 3 will be given 10ml of the energy drink V everyday

test plant 4 will be given 10ml of coca cola everyday

all the test plants are being exposed to natural sun light.

and the following are the plant results so far.

day 1-2; test plant 1 has grown zero cm

test plant 2 has grown zero cm

test plant 3 has grown zero cm

test plant 4 has grown zero cm
