Pot needs the sun to grow, but once your herb hits maturity you want to block it from the light. If you don't, you're going to speed up the decaying process. You don't want that. You want your ounce of herb to stay as fresh as possible for as long as possible. And we don't blame you. We support you with the XL UV Jar.

We have the perfect cleaning companion to make using Smoke Soap even easier! Get your ResCaps here.

We are proud to introduce our redesign of the Kargo water pipe! The Kargo 2 is everything we loved about the old piece along with some great additions like percs, a better fitting lid, and an overall innovative design that lets you have access to your juiciest nugs right where you need them. The smaller chamber and sidecar mouthpiece make this Kargo super stable and reliable. The Kargo 2 Hammerhead perc is a two-sided inline oriented showerhead that effortlessly pushes water and bubbles to the sides of the chamber. You can rip as hard as you want on the Hammer and it will not slow down. This Kargo 2 DOES NOT COME protected by a one year warranty. Get the warranty here.
