The FlowerPot B2 is a Grade 2 titanium ball vape head from Cannabis Hardware. Ruby balls sit inside the head, which is heated by a 20-mm coil connected to a PID controller. The B2 was designed for both herbs and concentrates, and that is precisely why the manufacturer discontinued it: the head and bundles are listed as “Sold Out” at Cannabis Hardware (as of October 11, 2026). Here you can learn how the B2 is constructed, which temperatures Cannabis Hardware specifies, and what you should look out for if you still find a device at a retailer or on the used market.

What is the FlowerPot B2?
The FlowerPot is the corded desktop system from Cannabis Hardware. It consists of a heating head, a bowl for the material, and your own water pipe. You place the head on the bowl; when you inhale, it heats the air, which then flows through the material. Several heads are available for the system, including the B0, B1, and B2.
The B2 evolved from the “Screen Baller,” a ball-filled diffuser for the older Vrod head. Cannabis Hardware turned it into a separate head: a dedicated bowl nut leaves as much room as possible for balls inside, and a dedicated Carb Cap was added. According to the manufacturer, the B1 is a combination of the B2 and the Weedeater, intended for anyone who wants a ball vape without the additional work involved with concentrates.
Construction and material
The head is made of Grade 2 titanium and, according to the manufacturer, is produced in Boynton Beach, Florida. Earlier versions of this page mentioned stainless steel balls and a stainless steel head; neither applies to the B2. The balls are ruby. Sapphire, quartz, or SiC balls also fit and, according to Cannabis Hardware, alter the flavor and performance.
The design principle was developed from the Vrod: its diffuser was milled out internally until it could accommodate 58 quartz balls measuring 4 mm. According to the manufacturer, this more than doubled the heating surface. Instead of flowing through straight channels, the air has to travel around the balls, which improves efficiency.
The B2’s 22-mm diffuser accepts woven screens or machined screens and holds 3 or 4 mm ruby balls. For one fill, Cannabis Hardware calculates 11.2 g of the 3-mm rubies (approximately 200 pieces) or 10.2 g of the 4-mm rubies (approximately 75 pieces). The head included the B2 nut, a 28-mm SiC dish, the dab attachment, and the screen diffuser.
Coil, controller, and temperature
All FlowerPot heads are designed for a 20-mm coil. The B1 accepts any standard 20-mm coil, while the B2 requires the CH coil or one with identical dimensions according to the FAQ: a bevel in the head’s thread is intended to make full-surface contact with the coil so that heat transfers effectively. The coil is available for 110 or 220 V. It is regulated by a CH or Auber RDK controller.
You set the temperature on the controller. This is the temperature at the head, not the temperature of the air at the material. Cannabis Hardware provides the following information:
| Specification | Value | Source |
|---|---|---|
| Normal controller range | 288–427 °C (550–800 °F), never higher | FlowerPot FAQ |
| Starting point according to the FAQ | 316 °C (600 °F): air at the material approximately 190 °C, bowl approximately 232 °C | FlowerPot FAQ |
| Typical range for ball vapes | 260–343 °C (500–650 °F), starting at approximately 288 °C | Ball vape guide |
| For more flavor | approximately 274–316 °C (525–600 °F); higher settings produce denser vapor | FlowerPot page |
| Heat-up time | 3–5 minutes, the full 5 minutes the first time | FlowerPot FAQ |
Since ruby balls became available, the manufacturer says that herbs require significantly lower temperatures than before. Start at the lower end and increase the setting in small increments of approximately 10 °F until the flavor and vapor suit you. According to the FAQ, the head needs approximately 5 minutes after each adjustment for the temperature to stabilize. Once it is hot, it maintains the temperature continuously; you do not have to wait between draws.
How to use the FlowerPot B2
1. Set it up
Insert the coil into the head, connect the coil to the controller, and plug the controller into the power supply. Place the head on the stand. Cannabis Hardware considers the stand, insulated holder, and handles integral parts of the FlowerPot: the head and coil become extremely hot, and the manufacturer recommends the aluminum handle for the coil.
2. Heat it up
Set the temperature and wait 3 to 5 minutes, allowing the full 5 minutes the first time. According to the FAQ, the head can then remain on the stand for hours.
3. Prepare the material
Grind finely. The finer the grind, the denser the vapor, according to Cannabis Hardware; the manufacturer states that multi-stage grinders do not grind finely enough. The titanium screen in the Shovelhead bowl is designed for material this fine. The bowl sits on your water pipe using a joint adapter.
4. Inhale
Place the hot head on the bowl and inhale. The air is heated inside the head and flows through the material. According to the manufacturer, the Shovelhead bowl also adds heat through titanium-to-titanium contact, which is why Cannabis Hardware describes it as a combination of convection and conduction. Afterward, return the head to the stand.
5. Concentrates
Concentrates are placed on the SiC or sapphire dish at the top of the head. You need the Carb Cap for this: it controls the airflow and lowers the pressure above the dish. This made it possible to vaporize herbs underneath and concentrate on top in a single draw.
Why Cannabis Hardware discontinued the B2
The B2 was originally designed so that herbs and concentrates would work at similar temperatures. With ruby balls, the temperature required for herbs dropped significantly. This made the gap between herbs and concentrates too large for a single head capable of handling both simultaneously. Concentrates also made cleaning and maintaining the ruby-filled head labor-intensive.
Cannabis Hardware therefore reorganized its product lineup: for herb-only use, the manufacturer recommends the FlowerPot B1, while devices such as the MOAB and Airstream are recommended for mixed use.
Bundle contents
The Standard Essentials Bundle included the B2 head, 4-mm rubies, a Carb Cap with a wooden handle, the Shovelhead bowl with a titanium screen, joint adapters for 14 and 18 mm, a stand, an insulated holder, an aluminum coil handle, a 20-mm coil, and either a CH PID or Auber RDK controller.
The Injector Essentials Bundle instead included a head with an injector-style diffuser and an injector-style glass bowl for 14 or 18 mm. The injector diffuser is built around the 18-mm joint and therefore fits many commercially available glass bowls.
Neither bundle included a water pipe. Joint adapters are available in 10, 14, or 18 mm, with either male or female joints, so the FlowerPot can fit your glass piece.
Warranty
Cannabis Hardware provides a one-year warranty on metal parts and its own controllers, and 30 days on coils. SiC, sapphire, and quartz dishes are excluded unless they arrive damaged and you report the damage within 24 hours with a photo. Auber controllers are covered by Auber’s warranty. You are responsible for shipping costs in a warranty case, and the warranty is nontransferable.
Is a FlowerPot B2 still worth buying?
Yes, if: you find an offer from a retailer or on the used market and want to use herbs and concentrates with one setup. Check beforehand whether the CH coil (or an identical model) and a controller are included. Cannabis Hardware no longer supplies new heads, and the warranty does not transfer when buying used.
Probably not, if: you only vaporize herbs. For that purpose, the manufacturer itself recommends the B1, which accepts any standard 20-mm coil.
