Dendrobium nobile species - when to resume watering?

[Ffion]

I have given my Dendrobium nobile a really harsh winter treatment for 2 months and it is now full of tiny flower buds. Should I resume watering now (I've kept it totally dry) or is it better to wait until they grow a bit more? There's also a 5cm new shoot growing at the base that hasn't seen water yet.

When the growth begins (flowers buds included) that's when I resume watering. Not sure if that's what experts recommend but that's what I do.

Edit June 15 2020:
Yamamoto Dendrobiums in Japan hybridizes and produces a great number of these plants. Their Web site formerly had excellent growing information for hobbyists. Unfortunately it is no longer there. You can still look at the varieties they grow, and maybe see one very similar to yours.

I saved the page, and summarized it in a post in this thread:
Uncertain if Dendrobium is still alive

Yamamoto now has a page showing how to force Dendrobium nobile for Christmas flowering in Japan's climate. There is a lot to learn from that page, but it is intended for growers who can artificially heat and cool their greenhouses during off seasons. Note they use coconut husk for growing medium, which many orchidists would say retains too much water for orchids. For many orchids that is correct, but this is a very thirsty orchid.

Thanks but from what I've read the D.nobile species require more severe winter rest, lower temps and dryer conditions to flower than the quoted Yamamomoto dendrobiums - hence my confusion.
