Does altitude Affect Cultivation??{merged}

[HatchetMan]

I was wondering if my altitude would affect my growing. I was hit with this thought while browsing Ralphsters for some spores. When i saw the Tak Mountain cube. It said it was found in the high mountains. My altitude is pretty high. Not mountain high but high. Albuqurque New Mexico to be exact. I wanna grow some shiitake . You know what i meen.

You'll be fine. I lived at 5,543 feet above sea level at one time and didn't do anything differently than I do now @ sea level......

no....but if your using a PC then you might need to adjust...depening on your Alt

Correct. You'll need to add 5% per 1000ft. for anything over 2000ft. above sea level. In other words, if you're at 3000ft. above sea level, you'll need to add 5% to the total pc time. 4000ft above sea level, 10%. 5000ft above sea level, 15% to the total pc time. And so on.....

atmospheric pressure at sea level is around 14.7 psi and considered a norm. so if you pc at 15 psig (pounds per square inch guage) you actually have 29+ psia. absolute pressure is psig + atmospheric pressure. there is reduced absolute or atmospheric pressure at higher altitudes, so your 15 psig on your pc is right, its the normal atmospheric pressure that differs. increasing your pc time will help guarantee sterilization. Temperature is directly associated with pressure. You will have a rise in temperature with increased pressure, and the opposite is also true. objects under pressure also have a higher boiling point. 212f is the norm at the above 14.7 psi.

Thanks for all the help guys!! I was worried for a while!

Im at 4800 ft and I dont adjust anything and things work great

i just recently moved up into the mountins in colorado from michigan, i had tons! of luck there. and now that im getting settled in here were of course no one knows me..wink wink.... i was wondering if the altatude would have any efect on my texans and golden teachers. im about 9,000 feet above sea level, any one know? thank.s a bunch..

Yes, my first mushies were done at over 6,000 feet above sea level in wyoming and I look back now and notice the difference and why I wasn't so successful. Pressure cooking I only had success with whole grain rice. So there must be a difference in that, hopefully a smarter person can answer that
They need a lot more moisture, really drier air so humidity is a factor.
Good luck, and its beautiful there!

Altitude affects the temperature at which water boils. Check your pressure cooker's manual and it will probably recommend much longer cooking times for canning foods at higher elevations. Probably add 15 minutes for every 1000 feet of elevation change or something like that.

Insight, I merged your thread with an older one.

When pressure cooking at altitudes over 2000 feet, the cooking time should be increased. Increase cooking times 5% for every 1000 feet above 2000 feet. Increase cooking times as follows:

3000 ft: 5% 4000 ft: 10% 5000 ft: 15%
6000 ft: 20% 7000 ft: 25% 8000 ft: 30%

i'm a mile high and dont seem to have contam issues with standard pressure cooker times. but i usually use the longer time estimates given around here anyhow.
