Update 5 days later.
Note: plants CB 2,4,6,7 all have stayed short and uniform so far. (2 inches)
Numbers 1,3,5 all stretched at the same rate. (2.5 inches.)So i would consider these tall and uniform. Note 2: Number 3 is the tallest at a whopping 3 inches lol. Growing the fastest as well.
Almost time for me to move them up.
