Safely slowing bud growth?

[FairyInTheFlowers]

Okay, I am sure everyone of you wish there was a way to speed up bud growth and development, but is there a way to safely SLOW DOWN bud growth? I have a Phal. ATL Crossing that has a bud developing, and a Phal. Penang Girl that is also growing a bud, but that is slightly younger. I am planning on crossing the two with Penang Girl being the pod parent, but the ATL Crossing bud is larger, and will definately open sooner, since I want to leave the Penang's bud on for about a week (this will be it's first bloom under my care), The ATL Crossing's bud could be up to two weeks old, thus making the pollen less fertile. So here I ask again the question, is there ANY way to slow down bud growth by even just a small fraction, without any chances of bud blast? Any responses and thoughts would be much appreciated!

Growing the one you want to slow down in a bit cooler area might help.

Keeping one phal cooler than the other will help, if you can do so. Not sure however what the "safety margin" is on this!

Thanks for the ideas! Do you think lowering the light levels would work also? I already have it in an area that gets to about 17C at night, and I don't think I can get it an colder than that.

I would think that two weeks on a flower that can last for two or three months wouldn't show that much loss of vitality. I say a two week old pollinia is better then risking bud blast by moving it to colder temps.
