Grow area to Show area bud blast issues
 

I have an intergeneric onc. that had many buds growing on a very tall flower spike. It actually grew so tall that I had to remove it from my grow chamber while the buds were fairly immature. After removing it from the warmer and more humid chamber it was placed in the normal environment of our house. Many of the buds in the middle of the spike just stopped growing. The buds at the top of the spike bloomed and have been blooming for several weeks.

My assumption is that the abrupt change in environment, when the buds were at their most vulnerable, was the cause of the bud blast.

Do others that have a "place to grow" and a "place to show" experience this same issue?

Would leaving the plant in the chamber until the first buds start to open possibly prevent the problem in the future?

FYI - The chamber runs 45-60 % humidity, and 80/68 degrees. Day/night respectively.

It was moved to a 20 % humidity 70 degree home.

Thanks,

The environmental change can, in my experience, cause issues with forming buds. The change from your grow area to your show area is pretty significant. I leave my plants very still while buds are forming. Once the flowers are open, though, I move them around a bit so that the flowers will be where I can enjoy them.

That response is what I expected to hear. In the case of the onc., it was out in the "home" environment probably 4 weeks before the first bud even popped.

I have not had the issue with other orchids, but I have left them in the chamber until the first bud pops. I am assume that is much safe than would I had to do with my too tall for the chamber onc.

Based on your input, I will try not to even move them when in the chamber if buds are forming.

Thanks for the input.
