The FlowerPot B1 is Cannabis Hardware's dedicated flower ball vape, with a 19-hole titanium top and a wide 3/4-inch air column. In our sessions it cleared a 0.25 g load in 1-2 hits through convection, powered by 3 mm ruby balls packed inside a Grade 2 titanium head.
This is a wired desktop that demands commitment: a water pipe, PID controller, a few minutes of heat soak, and permanent desk space. What you get in return is extraction power that outperforms every portable we have tested and most desktop vaporizers too.
Cannabis Hardware built the B1 from its WeedEater head, machining out the inside to hold ruby balls. The B1 is still in Cannabis Hardware's lineup and a consistent pick in our best ball vaporizers and best desktop vaporizers rankings. If you are new to how ball vapes work, the B1 plays by completely different rules than any session or portable vape you have used before.
What's in the box
The standard B1 kit ships as a complete wired system. Expect the B1 titanium head pre-loaded with 3 mm ruby balls, a CH or Auber PID controller, 20 mm coil, and titanium Shovelhead bowl. You also get 14 mm and 18 mm posts, a threaded heat stand with an insulated heat post, an aluminum handle, a 22 mm diffuser, a titanium screen and a power cord.
You need to supply your own water pipe with a compatible joint size. Budget for a rig if you don't already own one.
Grade 2 titanium built to outlast your glass
The B1 head is machined from Grade 2 titanium, the same material used across Cannabis Hardware's full lineup. It feels dense and solid the moment you pick it up.
The vapor path runs through ruby, titanium, stainless steel, and glass (your water pipe). No plastic touches the airpath at any point. The aluminum stand gives the hot head a safe place to rest on a heat-resistant surface.
Build quality earned the top sub-score in our testing. Every threaded connection fits precisely, and the titanium has shrugged off daily heat cycling in our use. The weakest link is the PID controller, whose commodity-grade electronics don't match the machined head. Metalwork and CH controllers carry a 1-year warranty, coils 30 days, and Auber controllers follow Auber's terms.
The 20 mm coil is rated at 100 W and comes in different mains voltages. It connects to the PID through a braided cable with an XLR plug, and that plug is worth checking. Pin wiring differs between controllers, including older and newer CH units, so match your coil and controller with the power off.
Ruby-powered convection rewards a steady pull
The B1 head is packed with ruby balls (3 mm standard since June 6, 2023, with 4 mm also available), creating an obstructed air path that forces heated air around every sphere. Each ball absorbs heat from the coil and from its neighbors, building a thermal network with far more surface area than a solid heater.
That stored heat rewards a slow-to-medium, steady pull, which gives the air time to pick up heat on its way through. Rip too hard and the air can arrive cooler. Your lungs matter as much as the dial, and that is what separates the B1 from conventional desktops and portables alike.
Opened up, the design is simple: a titanium head packed edge to edge with ruby balls, closed by a drilled cap.
Ruby balls fill the heater head, with the drilled cap beside it.
Heat soak takes 3-5 minutes, then hits are on-demand
The coil reaches your setpoint quickly, but the ruby balls need longer to heat through. Give the head 3-5 minutes, and a full five if you're new to ball vapes. Pulling before the balls are saturated produces thin, unsatisfying vapor.
Once soaked, the B1 becomes a true on-demand vaporizer. Load the Shovelhead bowl, set it in your water pipe, lower the head over it, and inhale. Put the hot head back on its stand between draws. In our sessions, a 0.25 g load came out evenly browned AVB after 1-2 pulls.
Best FlowerPot B1 temperature settings
We settle between 288°C and 343°C on the PID. Lower settings favor terpenes for flavor-forward hits, and higher settings hit harder. Cannabis Hardware suggests starting at 316°C, and its older controller quick-start uses 343°C.
| PID setting | When we use it |
|---|---|
| 288°C | Our starting point while learning, with 0.1-0.15 g loads, and the most flavor-forward end |
| 316°C | Cannabis Hardware's suggested starting point |
| 343°C | The top of our range and the older CH quick-start setting, for the hardest hits |
One detail worth knowing: the PID reads the heater, not the air hitting your cannabis. Treat the display as a dial setting and let taste guide you. Our temperature guide explains what each range brings out.
You can customize the thermal behavior by swapping ball materials. Ruby, sapphire, quartz, and SiC are all options, and different materials change heat retention and flavor character.
Wall power, no battery to manage
The B1 runs on wall power through its PID controller. No battery, no charging, no session limits. Once the rubies are soaked, the controller holds them at temperature for your whole session.
Pack a fresh load whenever you want a hit. This ready-when-you-are behavior is the desktop ball vape's core advantage over portables. When you're done, switch it off, since Cannabis Hardware says never to leave the coil running unattended. The Auber RDK controller, one of the two kit options, shows coil and set temperatures on separate readouts.

The trade-off is zero portability. The B1 is permanently tethered to an outlet, and the combined footprint of the head, stand, PID controller, and glass rig claims real desk space.
Loading takes 10 seconds, mastering takes a week
Loading the Shovelhead bowl is fast. Scoop finely ground cannabis in loosely (the shovel shape makes this intuitive), set it in your water pipe, and lower the B1 head on top. The whole process takes 10 seconds.
The learning curve lives in your draw technique. Draw speed, lung capacity, and heat soak timing all affect the result. Pulling too early, too hard, or with too much material loaded produces mediocre vapor that undersells the B1's capability.
We started with 0.1-0.15 g loads at lower temperatures, around 288°C on the PID, and worked upward. The B1 delivers more vapor than most people expect on the first pull, and it escalates fast at higher settings.
The Shovelhead uses a replaceable titanium screen, so you can swap in a fresh one whenever the old one darkens.
Cleaning is straightforward. Power off, unplug, and let everything cool completely. The bowl and screen soak clean in ISO alcohol, then rinse and dry them fully. Keep the coil, controller, and cables dry. Your glass rig needs regular cleaning too, but that is true of any water-filtered setup. For the head, check screens and connections now and then and follow the instructions for your exact model.
For former smokers making the transition to vaporizing, the B1's bong-style delivery makes the switch feel natural.
FlowerPot B1 vs B2, B-Zero, Freight Train and Universal Baller
The B1 competes in a growing ball vape market. These matchups represent the most common cross-shop decisions.
| Vaporizer | Our score | Vapor quality | Heating | US list price |
|---|---|---|---|---|
| FlowerPot B1 | 8.2 | 9.6 | Convection | $515 |
| Freight Train | 8.5 | 9.0 | Convection | $399 |
| Universal Baller | 8.4 | 9.6 | Hybrid | $500 |
| MiniNail Flower Wand | 8.2 | 9.3 | Convection | $299 |
FlowerPot B1 vs FlowerPot B2
The FlowerPot B2 is Cannabis Hardware's discontinued dual-use head, with a SiC or sapphire concentrate dish for flower and concentrates together. Cannabis Hardware retired it because the two want different temperatures and the combo made cleaning harder.
In our testing, the B1 draws more openly and delivers more even extraction. The B2's extra draw resistance sets a slower pace, and for flower-only use we'd take the B1. See our Cannabis Hardware brand guide for the current lineup. If you find a B2 and want the double-decker experience, it remains a top-tier machine, as long as parts are still available.
FlowerPot B1 vs FlowerPot B-Zero
The FlowerPot B-Zero is Cannabis Hardware's entry-level ball vape. Its bare head costs roughly half what the B1 head does, and it uses a different injector and screen arrangement.
The B-Zero hits hard for its price and also runs on a 20 mm coil, but not every part swaps across. It takes the Rev J Shovelhead bowl (older bowls can be too wide), so check revisions and wiring before mixing parts. In our sessions, the B1 delivered noticeably thicker vapor at equivalent settings. The B-Zero makes sense as an entry point if you plan to upgrade within the FlowerPot ecosystem over time. The B1 is the buy-once choice.
FlowerPot B1 vs Freight Train
The Freight Train 8.5 from Old Head uses a Grade 2 titanium heater with 4 mm rubies, a heat shield, and an integrated PID stand. Its 18 mm injector drops into a supplied bowl with a 14 mm male joint, and its wide airpath rivals the B1's open draw.

In our sessions, performance was close, with similar intensity from both. The Freight Train ships as a more self-contained kit, while the B1 offers deeper customization through Cannabis Hardware's modular ecosystem. The Freight Train costs less and suits buyers who want a turnkey experience. The B1 fits users who plan to explore different configurations over time.
FlowerPot B1 vs Universal Baller
The Universal Baller 8.4 from Terp Chasers Club runs wired or wireless, packing roughly 1,000 ruby balls in its metal setup or 500 in its wireless quartz one. With the right quartz insert, no metal touches the vapor path at all.

In our sessions, the Universal Baller had the edge in flavor purity and versatility. The B1 extracted more aggressively, helped by some contact heat where the titanium bowl meets the head. Flavor-focused users will prefer the Universal Baller's quartz path. Power-focused users will prefer the B1. Both sit at comparable flagship pricing, and our FlowerPot B1 vs Universal Baller comparison goes deeper.
Is the FlowerPot B1 worth it?
Heavy daily cannabis users who want bong-style hits from a vaporizer will find the B1 clears a load faster than any portable we have used.
Existing FlowerPot owners looking to upgrade from a V-Rod or B-Zero can often reuse their coil, PID controller, and accessories. Check bowl revision, coil size, voltage, and wiring first.
Former combustion users who tried portables and found them underwhelming will feel the difference within a single hit.
Skip it if:
- You want a vape you can carry. The B1 runs on wall power and lives on your desk.
- You don't own a water pipe and don't want one.
- You want concentrates. The B1 is flower only.
- You want a hit the moment you switch on. The rubies need 3-5 minutes to heat through.
- Flavor purity matters more than power. The Universal Baller had the edge there in our sessions.
Final verdict
The FlowerPot B1 is the ball vape VapeExperts recommends for dedicated flower users who want the most aggressive desktop extraction we have tested. The Grade 2 titanium build, wide-open airflow, and ruby-powered convection deliver vapor quality that outclasses most desktops we've used, at any price.
It demands space, a water pipe, a few minutes of warm-up, and a willingness to master its technique. For buyers who accept those terms, the B1 is an end-point purchase.
