that is the first time I have ever seen a seedling staked like that, but wow it worked and it is healthy, you got my attention, cant wait to see it looks like your doing good so far,

also it is not very nesccesary but you can also transplant that little cube into a bigger cube, it might help, no just with balcing once it gets bigger, but with helping those roots realy get massive in the begening, its standard prcatice, usualy the little clone cubes go into a 3x3 block and veg for a while then when the roots come out then they go into the bucket.
