speeding up keiki growth.

[shahrezsyed]

i had a dendrobium noid. it died but one cane was totally green but fell off. then, i put the 4 inch cane in a freezer bag just like the sphag n bag method.ina month it sprouted a keiki.then, the keiki grew to abt 1 inch tall and has two ,1 mm roots.
just wanted to ask that does the small 4 inch cane have enough food to support the keiki till it is ready to be potted? and is there any way to speed the keiki ,s growth up?
