The bags are available in 5 gallon ($149.99) and 20 gallon ($299.99) varieties.
“The Essential Extracts Bags are constructed from the strongest non-leak material available, and are guaranteed not to rip, tear, or crease.” Nikka T has long been a proponent of Mila’s Ice-O-Lator bags, so I was a bit surprised to see that each set of Essential Extracts bags comes with 6 different bags to separate glandular trichome heads of various sizes – 25 micron, 38 micron, 70 micron, 120 micron, 160 micron, 220 micron.įor comparison, Bubbleman’s Bubble Bags and Boldtbags each come with 8 different sizes of bags. At the same time, I was intrigued to see what would make the Essential Extracts Bag s stand out from the crowd. Knowing that Nikka T goes to great lengths to produce quality medicine for his patients, I was excited to see what the Essential Extracts team came up with as far as water extraction bags are concerned. In turn, Nikka T and a few more of America’s best hash makers took it upon themselves to lead a solvent-less revolution through community-sourced education.Įssential Extracts Bags 2.0: Nikka T’s Very Own Hash Bags However, butane honey oil (BHO) began to surpass water hash in popularity, and interest in water hash really seemed to fade until recently. Mila Jansen and Bubbleman have each built a reputation for crafting the first generation of hash bags, as well as pioneering the initial water hash movement with legends like David Watson and Kenneth “K” Morrow. “Essential Extracts have released a number of tools for patients who wish to produce and medicate with their own solvent-less hash.” Of course this makes sense when you consider that Nikka T has spent over 10 years perfecting his methods to produce the highest quality of solvent-less wax possible. Holding to that mission, the Essential Extracts camp has won a laundry list of awards, including 1st place at the US Cannabis Cup in 2013. They specialize in solvent-less extraction methods (ice water extraction, dry sieve, etc.), while striving for the “ultimate in purity and quality.” Essential Extracts Releases Tools For Hash Connoisseursįounded by Nikka T in 2010, Essential Extracts is one of the premier concentrate companies in Colorado. They are available in two sizes (5 gallon and 20 gallon), and were developed to provide hash-makers with quality hash bags at an affordable price. The resulting video file will be a MPEG4 encoded AVI file.Tested and approved by Nikka T himself, the Essential Extracts team has unveiled the second version of their ice-water extraction bags. Numbers greater that 1800 KBits usually works fine. For ffmpeg use KiloBytes/Sec, for mencoder use KiloBits/Sec (e.g 2400 Kbps vs 300 KBps).

The methods described below has been tested using ROS Fuerte on a 64bit Ubuntu 12.04 machine.
XTRACTOR BAG UPDATE
UPDATE (June 2014): bag_tools ROS package includes a node called make_video.py which converts images inside a bag file into a video, similar to the manual workflow described in this post.
