This definitely isn't a curing problem. I can reproduce it with over a dozen quality strains, and only on a Ti. The OG doesn't do this with the same material. I just can't figure why heat would be concentrated on the end so much?
Hi, I agree with
@HD Springer. This issue is less likely to occur if you dont focus your heat too much on the tip. I am a super new vapcapper still learning the ropes.
I have actually been avoiding heating the tip altogether. I find it just brings on the click very early, before the load has reached a good temperature. So it will just be a slower extraction that way as well.
In contrast, as many report, focussing heating on the digger outer end is the way to get fadt extraction, thick vapor and very consistent results. The load is spent/extracted faster. I would like to use the vaporizer this way, but it is more aggravating to my sensitive lungs.
So I have been aiming the quad torch at the middle of the cap mostly, and just playing around with lighter distance. The quad torch flame is big though, so it heats a large section of the cap.
I get the material very dark brown at times, bit it is never green and brown, always even.
I am cautiously testing the diggerouter area now, but I stay away from the tip. To me it defeats the purpose of what Im trying to do by slowing the whole thing down.
I want to get medicated and have little physical energy, so large inhalations on demand suit me well.
The vapcap is something totally different I am trying. But I want quite fast extraction for a powerful effect.
Tonight I tried unground buds for the first time. I put a little bud, well under 0.1, into the Ti tip whole. I put some think different which had an organic fert I am allergic to, not too bad the allergy.
I heated at the diggerouter end first and focused on middle, never went towards the tip (I think Im sacred of it!), I had the carb restricted and tried
@Squiby 's advice, to "mouth pull".
I think this is like stoking up a fire, sort of succking on it gently at first. The vapor was flowing thick right away first toke, but it still tasted very good and smooth. I always lose track, but the following cycles (all with one long slow draw) gave easy smooth, tasty and dense clouds.
It was probably the best I have got it to work yet. It seems smoother for sure. I followed it up with a white widow bud, which Im not so allergic to, and it was really good again.
When I tipped the loads out the whole bud was a perfect even brown right through.
Edit- here is a vaped white widow nug, a little browner than ideal but not charred at all. A very small bud gave great clouds, smooth and cool and tasty. More than I would expect grinding up more, I may be wrong.
