Here's my attempt at a DIY freeze-dry rig for ice water hash. The vacuum chamber is 4" PVC pipe that fits in the freezer, hooked up to a regular air conditioning vacuum pump, using 1/8" copper tubing that fits under the gasket of the deep freeze. I don't have a very good gauge to measure vacuum, but it boils water at room temperature, so it should sublimate frozen moisture at -10°F in the deep-freeze (-23°C).
The wife would rather I be finishing the upstairs bathroom instead of fooling with my canna experiments. Next up is to upgrade the 1-1/4" lead shower drain to code, which is 2" PVC (see work light in the 2nd pic). Right
@PinkyNotTheBrain ? Maybe I'll try a hash run first, the bathroom project has already waited since I got this house in 1992...
