Hi,
Yes people use different temps to keep their BP's - VPI being one of the main ones I can recall.
But people have suggested the same fixes for every single genetic problem for years upon years, Higher/lower temps, higher/lower humidity bigger females/ grown slower.
They have never, ever even helped with any of the problems and, frankly, are only suggested because those are the only things we can change - not because they make a great deal of sense as a solution to the problems.

Is worth a read for one persons experiences with deserts and temps.
I'd quite like to see what happens if someone crosses deserts into the sub saharan giants in terms of their growth rate etc. But I can't afford deserts at the moment in terms of gambling. You plainly feel you can so good luck with it and keep us posted.
