A day time picture from the front:


and from the top:


and this picture is from the back showing how the plants are leaning towards the sun as mentioned in the previous post:


and the final picture is an arial view of the 2nd lot of plants for the repeated experiment:


The current heights are:
for the original 7cm
overwatered: 8cm
normal: 11 cm and underwatered: 9cm

for the 2nd experiment (batch 2):
overwatered: 2 cm
normal: 3 cm
underwater: 2.5 cm

all plants are healthy and green and i definitely think thining them/ not putting as many in the pot was a good idea :)
