Bubble does NOT work well in my experience with the rev or dart. It'll sit there on that ceramic, heatin up, but vapor production off the bubble is not that great. HOWEVER, bubble goes well in the T1 in my experience as long as you surround it with screens, and put it in a good envelope of flowers. Just melts into the flowers and you get a THICK cloud of vapor, and can def taste the extract.
But yeah, you really need a pretty liquidy full melt extract like wax, or shatter glass, or oil, or BHO, or whatever people like to call these solvent extracts. If you're only going to be making bubble, keep the T1, and if you want stuff to use in the Rev or DART, make BHO.
My 2cents and all.
Ya, BHO is super easy to make, look up the Stainless Steel Turkey Baster method. The glass extractors make me nervous, I have one, but I rarely use it. There's a lot of pressure that can build up in there.
DO IT OUTSIDE!!!
Dry your flowers out very well first. I use very dry whole buds. And take the time to properly purge.
Watch some videos on youtube so you have an idea of what to expect.
It's soooooo worth it. BHO is on another level. My rev and omicron cart combo is a game changer for me. My LB, which used to come with me everywhere, has been sitting on the shelf since my rev came.
Take the leap, you can get a dart for ~$60, the materials to make the BHO(stainless steel baster, glass pie pan, coffee filter or fine screen, butane, will be roughly $20. My last run I put less than 10g in, and got enough BHO to fill an omicron cart to the brim and have a nice chunk left over, maybe .3 or .4, and I can still do another run of some less awesome oil, but still nice, and get at least another .1 or .2. I know it's tough in a non medical state to risk such a large amount on new process with a new device, it's quite a leap of faith. Take it man, this shit is the fucking coolest. I'm almost as excited for the rev/omi as I am for the cloud.
Each of my loads in the rev is about .05, so that last .4 will get me 8 loads, each of which will have me ripped for hours. Good times.
A gram in an omicron cart will last me weeks. I haven't touch my Ti nail since I got these things.
