No need to boil Ramie, but I did with a couple feet, used a water and VG bath, gently boiled for ~30 minutes. But only did that because I couldn't figure it out.
Have the Ramie in the Aqua, Rose, Russian, Taifun, and Magma, all vaping quite nice. Brought new life to my Aqua for sure. Have a fogger on the way, just couldn't help myself, lol, Aqua base with a huge tank, yeah, all over that. lol.
Ramie did take me the longest to figure out, compared to cotton or hemp, but once figured out, provides excellent wicking for all my builds, horizontal, vertical, we control the.... woops, wrong forum. But ya, liking this stuff, which is a good thing since I have 8 oz's of it. lmao.
