Learning how to make vape carts at home is easier than you think — if you follow the right process. Fordee from Herbistry420 walks through his improved no-clog recipe using winterized rosin and wax liquidizer for THC carts that taste great and hit smooth every time.
How To Make Vape Carts — The 5-Step Process
The key to how to make vape carts that don’t clog is starting with properly prepared rosin. Your starting material quality and preparation determine everything. Here’s the full process:
Step 1 — Decarboxylate Rosin for Vape Carts
The first step is to decarboxylate rosin for vape carts. Decarbing converts THCA (a solid compound) into THC (a liquid compound). While your vape pen heat would eventually activate it, decarbing first gives you a more liquid consistency that is much easier to work with and fills carts more smoothly.
Decarb your rosin at low heat (around 220°F / 104°C) until it stops bubbling. You will notice the rosin become noticeably more fluid. This step is essential — do not skip it.
Step 2 — Winterize Rosin Before Making Carts
The second step is to winterize rosin before making carts. Rosin contains fats, lipids, and waxes that come from the original plant material. These are the number one cause of clogged 510 carts. Winterizing removes this unwanted material by dissolving the rosin in ethanol, freezing it, filtering it, then evaporating the ethanol.
After winterizing, you are left with a clean oil that flows freely through a cart and resists clogging. In this video, Fordee started with 6.8g of rosin. After decarbing and winterizing, you typically lose 40–60% of total volume, leaving around 3–4g of clean oil.
Step 3 — Mix with Wax Liquidizer for THC Carts
The third step is to mix with wax liquidizer for THC carts. Wax liquidizer (such as the TPS USA Liquidizer Kit available on Amazon) is a formulation of multiple weights of propylene glycol with terpenes added. It thins the rosin oil into an e-juice consistency that flows perfectly through a 510 cart.
Use a 1:1 to 2:1 ratio of liquidizer to rosin. A 2:1 ratio (more liquidizer) creates a thinner, smoother-pulling cart. A 1:1 ratio makes a stronger, more potent cart with fewer puffs per gram. Heat the mixture gently with a magnetic stirrer at low heat (10–25%) until fully homogeneous. You can also substitute wax liquidizer with your own mix of propylene glycol, vegetable glycerin, and terpenes if you prefer.
Step 4 — How to Fill 510 Carts
Knowing how to fill 510 carts without making a mess takes a little practice. Here are Fordee’s tips:
- Keep the heat on — the oil stays liquid and flows easier when warm
- Use a blunt-tip syringe — precise filling without splashing
- Fill slowly — stop before the top to avoid overflow
- Cap immediately — twist the top on while still warm for a clean seal
- Be careful with heat — the syringe and hot plate get very hot; do not touch with bare skin
Step 5 — How To Make Vape Carts That Taste Amazing
From 6.8g of rosin Fordee filled 12 carts using this method. At roughly 5,000–6,000mg of THC in 6.8g of rosin, each cart packs serious potency. The Skittles-flavored liquidizer added a great taste — the final result hit smooth with no clogging and big clean clouds.
The dark color of the carts came from using hash as starting material rather than bubble hash. Using lighter starting material (like fresh-press flower rosin or bubble hash rosin) will give a lighter amber color in the final product.
Frequently Asked Questions
Why are my vape carts clogging?
The main cause of clogged 510 carts is residual fats, lipids, and waxes in the rosin. Winterizing the rosin before making carts removes this material and is the single most effective thing you can do to prevent clogging.
Do I have to decarb rosin before making carts?
Technically the vape pen will activate the THC, but decarbing first converts solid THCA into liquid THC, making the oil significantly easier to work with and resulting in a smoother-filling cart. It is strongly recommended to decarboxylate rosin for vape carts.
Can I use PG and VG instead of wax liquidizer?
Yes. You can substitute wax liquidizer with a custom mix of propylene glycol, vegetable glycerin, and terpenes. The wax liquidizer is essentially a pre-blended version of this with multiple PG weights for convenience.
