i was wondering the same thing.. except i was wanting to know how long does it take the spike to form??? The lil spike that is starting to come out on this dendrobium above is about this long -- coming from the tip of the cane... but it has been that way for weeks now. it was really really hot for awhile and now its just cloudy and raining. will a lil rain effect this plant to much? i think it has gotten wet over night a few times also. and now im afraid of crown rot. and if i bring it in its to cold lol so yeah
