With all the interest in the LR cart, I figure there's more than the normal number of interested folks on the thread right now? Maybe a good time to discuss technique? I'm by no means an expert, or even a heavy a user but it's a place to start.
I typically load about half a tenth (50 mg) at a time and melt it in before closing up. I pull the top straight up (twisting it makes a much bigger mess) and usually load oil in the top, everything else through the window. Kif and bubble go in the window lose, heated up some to soften them, and poked down with a toothpick before buttoning up. If anything got out and onto the widow (or any other) area I keep a small cloth patch with the concentrates to wipe it off with. Very little comes off this way, patches last a long time.
In the process suggested by Tim at TV, I fire it up and let it cook. It varies from load to load sometimes but let's say ten seconds? Take a 'test puff' and blow it out. Did it work? A second or two later, try again. Simple, works great. Finds the start of vaping (or the end of your battery) every time. As soon as it starts to 'get there' it's time to stop whatever else is going on and focus, focus on the hit that the machine delivers. Let it develop on it's own, start honking on it and you can mess it up. Don't let it back up and come out the vents either, keep a slow draw. Focus. Take it as it's produced. Until you can't hold any more or it gets away from you and you 'hit the chicken switch' (cut the power).
And you might want to be careful about taking another hit until you're sure.....
Kif and bubble get stirred every hit or two, I sometimes do this from the top, pulling the moutpiece only and fishing a long toothpick with a square end down the hole. It's easy to scrape the walls down, scoop up the mass and smash it into the wall a time or two to mix it and push it all back down again. The important part is not to scrape up the bottom. You never open it up and unlike oils and waxes only the bottom most bit is heated. It's like frying not baking. This means you can put a lot more material in without it choking. Otherwise I get half a dozen or so heavy (to me) hits this way. Then I load another few drops or bb size ball and go again (when the time comes, nice to have it ready and standing by).
Using 70% oil, each of those hits delivers about 6 mg of THC. Even 50% absorption means 3 mg to you and me. That should catch most guys attention you'd think?
Anyway that's my advice. Load small and often, take test puffs to find the start of vaping, and when it gets there focus on the hit. Works great for me. How do you do it?
