simon, or someone that is familiar with his method....

I didnt look through the thread again, but what is the highest humidity where buds are barely smokeable, and what is between barely smokable and perfect?

From what I recall, 70% starts the cure and 55% ends it. So are they smokeable at 70 (just not ideal taste/smell/smoothness) or not quite?

I cant seem to keep my hands on my finish product... out to patients before I can really cure much at all

I have used this method before and it works great. I would say 65%-55% is when it smokes best.

This is straight from Simons thread:
It's a very simple and effective process:

Cut the product, trim it per your preference, but don't dry it until the stems snap. Take it down while the stems still have some flex, but the product feel dry on the outside. This is a perfect opportunity to drop the dry-feeling flowers onto a screen and collect prime-quality kief that would otherwise get lost in the jar.

Jar the product, along with a Caliber III hygrometer. One can be had on Ebay for ~$20. Having tested a number of hygrometers - digital and analog - this model in particular produced consistent, accurate results. Then, watch the readings:

+70% RH - too wet, needs to sit outside the jar to dry for 12-24 hours, depending.

65-70% RH - the product is almost in the cure zone, if you will. It can be slowly brought to optimum RH by opening the lid for 2-4 hours.

60-65% RH - the stems snap, the product feels a bit sticky, and it is curing.

55-60% RH - at this point it can be stored for an extended period (3 months or more) without worrying about mold. The product will continue to cure.

Below 55% RH - the RH is too low for the curing process to take place. The product starts to feel brittle. Once you've hit this point, nothing will make it better. Adding moisture won't restart the curing process; it will just make the product wet. If you measure a RH below 55% don't panic. Read below:

Obviously, the product need time to sweat in the jar. As such, accurate readings won't be seen for ~24 hours, assuming the flowers are in the optimal cure zone. If you're curing the product for long-term storage, give the flowers 4-5 days for an accurate reading. If the product is sill very wet, a +70% RH reading will show within hours. If you see the RH rising ~1% per hour, keep a close eye on the product, as it's likely too moist.

Edit: Also found this that Simon said in the thread to answer a similar question someone had.
For smoking ~60% or a hair more is great. In terms on bag appeal, ~65% will deliver a sticky product. Much depends on one's expectations. The flowers will be curing, regardless.
