You want a medium grind, roughly the consistency you'd use for a hand-rolled joint or a dry herb vaporizer. A standard two-piece or four-piece grinder on a couple of twists will get you there. The goal is pieces that are small enough to compress evenly inside the mold but coarse enough to hold structure once the pressure is applied.

Grinding too fine creates a powder that compresses into an almost solid wall. When you pull the skewer out of a Mini CannaMold (1–2g) or Personal CannaMold, that overly dense material can partially collapse into the airflow channel, choking your draw. You'll end up relighting constantly and pulling hard just to get anything through. On the other end, leaving buds in large chunks means the packing stick can't distribute material evenly around the skewer. You'll get air pockets and soft spots that cause the cannagar to burn unevenly or canoe down one side.

A good test: after grinding, pick up a pinch and squeeze it between your fingers. It should clump slightly when pressed but break apart easily when you release. That texture packs predictably in any of the CannaMold sizes and still allows the compressed core to hold its shape when you open the mold. If you're using a four-piece grinder with a kief screen, the material that stays above the screen is exactly what you want to load into the press. Save the kief for topping the outside of your finished cannagar or mixing into the core for an extra kick.

Absolutely, and it's one of the biggest factors people overlook. Flower that's too dry will crumble under compression instead of binding together. When you open the mold, a bone-dry core tends to fracture and fall apart because there's no residual moisture holding the plant fibres to one another. That's especially frustrating with a larger mold like the Small CannaMold (3.5–7g), where you've committed 3.5 grams or more and don't want to watch it disintegrate.

Flower that's too wet creates the opposite problem. Excess moisture prevents the material from compressing into a firm, uniform cylinder. The core might feel solid while it's still clamped, but once you remove it and try to slide it into a Mini Shell Cones (Carton of 20), it can deform or swell as trapped moisture migrates outward. Wet cores also burn poorly; you'll get harsh, uneven smoke and constant relighting.

The sweet spot is flower that feels slightly springy when you squeeze a bud. If it snaps and turns to dust, it's too dry. If it feels spongy and leaves residue on your fingers, it's too wet. A Boveda or Integra humidity pack stored with your flower for 24 to 48 hours before packing can bring things into the right range, generally around 58 to 62 percent relative humidity. That level gives you enough natural tackiness for the ground material to bind under the pressure of the packing stick while still allowing the finished cannagar to light and burn cleanly.

The skewers and packing sticks included with Purple Rose Supply CannaMolds are functional tools, not permanent fixtures. Wood is porous, so it absorbs resin and moisture every time you use it. After several sessions, you'll notice the skewer gets stickier and harder to slide out of the compressed core cleanly. A rough or resin-coated skewer can drag material with it when you pull it free, partially collapsing the airflow channel you worked to create.

For the skewers specifically, a clean removal is critical to the whole process. If yours starts catching or leaving residue inside the core, it's time to swap in a fresh one. Purple Rose Supply sells replacement skewers, and they're inexpensive enough that treating them as consumable accessories makes sense. The packing sticks are a bit more durable since they're just pushing material downward, but once the surface gets rough or warped from repeated use and cleaning, they won't distribute pressure as evenly.

A practical approach is to wipe your skewer and packing stick with a lightly dampened cloth after each session to remove surface resin before it hardens. That extends their useful life noticeably. But once the wood grain starts raising or the surface feels tacky even after cleaning, replace them rather than fighting tools that aren't performing the way they should.

For the plastic mold body itself, a quick wipe with isopropyl alcohol on a cloth or cotton pad is fine for removing surface resin. You don't want to submerge the entire CannaMold in a bath of ISO for extended periods, though. Prolonged soaking can cause certain plastics to become brittle, discolour, or warp over time, and the mold's clamping mechanism needs to stay precise to produce a consistent core shape.

The wooden skewers and packing sticks are a different story. Wood soaks up liquid, so dunking them in isopropyl will saturate the grain. As the alcohol evaporates, the wood can swell, crack, or splinter. A quick surface wipe is the most you should do; anything beyond that risks compromising the smooth finish you need for a clean skewer removal. If your wooden tools are caked with resin to the point where wiping isn't enough, that's a sign they've reached the end of their life and should be replaced.

For the Rolling Glue (4 ml, Carton of 24) bottles and brush tips, there's no real reason to clean them with ISO. The glue is water-based and the built-in brush stays usable as long as you cap the bottle after each use to prevent the tip from drying out. If a brush tip does harden, running it under warm water for a minute usually softens it back up.

Yes, and this is actually one of the best practical advantages of the cannagar format. Because the core is so densely compressed, it holds its structure even after you put it out. A regular joint falls apart or tastes terrible when relit, but a well-packed cannagar from a Mini CannaMold (1–2g) or Personal CannaMold can be set down, extinguished, and picked back up later without losing its shape.

The cleanest way to put one out is to gently press the lit end against a hard, heat-safe surface like an ashtray until the cherry dies. Avoid crushing or smashing it, because even a dense core can crack if you apply too much lateral force. Blowing on the tip to extinguish it can push hot ash back into the shell and scorch the outer wrap, so let it suffocate naturally instead.

When you come back to it, you'll notice the flavour on the first few puffs is a bit more ashy than a fresh light. That's normal. Trimming or gently tapping off the charred end before relighting helps quite a bit. The relit portion will still burn slowly and evenly because the interior compression hasn't changed. Larger cannagars made with the Small CannaMold (3.5–7g) are especially well suited to this, since a 3.5 to 7 gram smoke is a serious commitment in one sitting. Being able to split it across two or three sessions makes the format much more practical for everyday use.
