Overview
The Purple Days (commonly abbreviated as PD) was a small, handcrafted log-style desktop vaporizer that became a beloved fixture in the dry herb vaporizer community during the late 2000s and early 2010s. Manufactured by a small artisan operation, the Purple Days was among the earliest and most iconic log vaporizers — a form factor characterized by a compact, cylindrical wooden body housing a fixed heating element powered by a standard wall outlet. The Purple Days utilized a primarily conduction heating method, with the user drawing air through a glass stem (loaded with a small amount of ground herb) inserted into a heated core.
The device operated on a 12V power supply drawing approximately 8 watts — an extraordinarily low power consumption that made it economical to leave plugged in around the clock, which was in fact the recommended mode of operation. Each unit was individually crafted from wood, and the PD became known not only for its exceptional herb efficiency but also for its artisanal aesthetic, with units often featuring unique wood species and finishes. The Purple Days is no longer in production, and original units are considered collectors' items within the vaporizer community.

Community Reception
The Purple Days was widely regarded within the vaporizer community as one of the gold standards for herb efficiency. Community members frequently praised the device for its ability to produce satisfying sessions from remarkably small amounts of material — often as little as a single pinch of ground herb loaded into the glass stem.
Pros frequently cited by the community:
- Exceptional efficiency: The PD was consistently ranked among the most efficient vaporizers available. One community member who owned a PD, Magic-Flight Launch Box (MFLB), HI (MyrtleZap/MZ), and Silver Surfer Vaporizer (SSV) rated the log vapes' efficiency as on par with or slightly above the MFLB, and significantly above larger desktop units like the SSV.
- Always-on convenience: Because of its extremely low power draw (~8W), the PD was designed to be left on 24/7, making it always ready for use with no heat-up wait time.
- Quality ABV (Already Been Vaped) material: Community members noted that the PD's fixed, moderate temperature produced evenly extracted AVB that was well-suited for cooking and edible preparation. One member specifically praised the "great leftovers to use for cooking" that the fixed temperature yielded.
- Artisan craftsmanship: Each unit was unique, contributing to a strong collector culture around the device.
- Small group suitability: The PD was considered ideal for solo use or small groups of two to three people.
Cons and limitations noted by the community:
- Fixed temperature: The lack of temperature adjustment was seen as both a strength (simplicity, consistency) and a limitation (less versatility compared to variable-temperature desktops).
- Not ideal for large groups: For parties or sessions with many participants, community members generally recommended larger-hitting desktop vaporizers like the SSV over the PD.
- No longer in production: Availability became a significant issue as the manufacturer ceased operations, making units increasingly rare.
- Desktop-only by default: The wall-powered design limited portability, though some community members explored battery-powered workarounds (see Accessories & Modifications).
Tips & Techniques
The community developed and shared a number of best practices for getting the most out of the Purple Days:
- Leave it on continuously: The PD was designed to remain powered on at all times. At only ~8 watts of power consumption, the cost of continuous operation was negligible, and this ensured the vaporizer was always at optimal temperature and ready for immediate use.
- Grind fine, pack light: The small glass stem chamber was designed for micro-doses. Community members recommended a fine grind and loading only a small pinch — enough to lightly fill the screen area of the stem without dense packing.
- Control temperature through draw speed: With no adjustable thermostat, users learned to modulate vapor production by varying their inhalation speed. Slower draws allowed more heat transfer and produced thicker vapor; faster draws cooled the herb and produced lighter, more flavor-forward hits.
- Multiple short sessions from one load: A single stem load could be sipped on across several brief sessions throughout the day, a technique the community referred to as "sipping" — perfectly suited to the always-on nature of the device.
- Save your ABV: The community widely agreed that PD leftovers were among the best for secondary use in edibles, owing to the gentle, even extraction at a fixed moderate temperature.
Temperature Guide
The Purple Days operated at a fixed temperature and did not include a user-adjustable temperature control. The exact operating temperature was not officially published with precision, but based on community observations:
- The fixed temperature was generally understood to produce vapor in the low-to-moderate range, prioritizing flavor and efficiency over maximum extraction or cloud production.
- Users reported that the PD did not extract as aggressively at high temperatures the way variable-temperature desktops (e.g., SSV) could, which contributed to both its efficiency and its reputation for producing high-quality ABV.
- One community member noted that the MFLB could "go a little higher temp" than the log vapes with their fixed temperature, suggesting the PD's operating point sat in a moderate range — likely in the vicinity of 185–195°C (365–383°F) based on community descriptions of vapor quality and ABV color, though this was not precisely verified.
Draw speed as effective temperature control:
| Draw Speed | Effective Result | Character |
| Very slow sip | Higher effective temperature | Thicker vapor, more extraction per draw |
| Moderate draw | Balanced | Good flavor with moderate vapor production |
| Faster draw | Lower effective temperature | Lighter, more flavorful, less visible vapor |
Maintenance & Cleaning
While detailed cleaning protocols were not extensively documented in the available thread data, the community's general guidance for log vaporizers of this type included:
- Glass stems: Regular cleaning of the glass stems with isopropyl alcohol (ISO) was the primary maintenance task. Reclaim (condensed oils) building up inside the stem was considered desirable by many users, as it could be harvested for secondary use.
- Heating core: Occasional gentle cleaning of the heater bore with a dry cotton swab or ISO-dampened swab (with the unit unplugged and cooled) to remove any particulate buildup.
- Screens: The small screens in the glass stems required periodic replacement or cleaning, as clogged screens could restrict airflow and reduce vapor quality.
- External wood body: Community members recommended avoiding liquid cleaners on the wood exterior to preserve the finish and craftsmanship.
Common Issues & Fixes
Based on community discussions, the following issues were noted:
- Unit not reaching temperature: Because the PD was designed to be left on continuously, users who turned their unit off and on may have experienced longer-than-expected warm-up times. The recommended fix was simply to leave the device on at all times.
- Weak vapor production: Usually attributed to packing the stem too tightly (restricting airflow), drawing too quickly, or insufficient warm-up time. The community recommended lighter packing and slower draws.
- Portability limitations: The PD required a wall outlet, which led some users to explore battery pack solutions. Community members discussed the possibility of running the PD from battery packs given its low 8W power requirement, though one member cautioned that DIY battery solutions involving soldering custom packs could pose safety risks (including potential for battery failure) and were "not stoner friendly." The community recommended consulting dedicated guides on portable power sources for vaporizers before attempting such modifications.
Accessories & Modifications
- Glass stems: The primary accessory for the PD. Different stem lengths and bore sizes could subtly affect draw resistance and vapor cooling. Replacement and spare stems were considered essential accessories.
- Portable battery power: Community members explored using 12V battery packs to power the Purple Days away from a wall outlet. Dedicated threads and guides existed within the community covering portable power sources compatible with the PD. Given the device's low 8W power draw, portable operation was theoretically feasible, though practical implementation required careful attention to voltage, amperage, and connector compatibility. The community maintained tip-and-trick guides specifically for this purpose.
- Water pipe adapters (WPA): While not a standard offering, community members experimented with adapting the PD's glass stems for use with water pipes, a common modification across the log vaporizer category.
Comparisons
The Purple Days was most frequently compared to other log vaporizers and ultra-efficient devices:
Purple Days vs. MyrtleZap (MZ) / HI
The MZ (also known as the HI or Heat Island in later iterations) was the PD's closest competitor in the log vaporizer category. Community members who owned both generally rated their efficiency as very close, with some considering them essentially interchangeable in terms of herb conservation. Both shared the always-on design philosophy and small-chamber approach. One experienced community member reported owning "several MZ's" and rated their efficiency as comparable to the PD.
Purple Days vs. Magic-Flight Launch Box (MFLB)
The MFLB was a portable, battery-powered conduction vaporizer, making it a fundamentally different device. However, both were celebrated for efficiency. Community consensus placed log vape efficiency as equal to or slightly higher than the MFLB. The MFLB offered true portability and the ability to reach slightly higher temperatures, while the PD offered hands-free, always-ready convenience at home and produced ABV that was more consistently suited for cooking. One member summarized the difference by noting that "the LB can go a little higher temp while the logs with their fixed temp offer me great leftovers to use for cooking."
Purple Days vs. Silver Surfer Vaporizer (SSV)
The SSV, a larger whip-style desktop vaporizer, represented a different philosophy: bigger bowls, bigger hits, and variable temperature control. Community members noted that the SSV used noticeably more herb per session but delivered substantially larger hits — making it preferable for group sessions or users transitioning from bong smoking. The PD was preferred for solo efficiency and micro-dosing. As one member put it, the SSV was reserved for "when I want a big hitter or have friends over," while log vapes like the PD were the daily drivers for conservative, solo use.
General Positioning
The community generally categorized vaporizers into use-case tiers, and the Purple Days occupied a specific and cherished niche: the ultimate solo efficiency device for home use. It was not trying to compete with hard-hitting desktops or portable units — it simply excelled at delivering maximum effect from minimum material in a beautiful, always-ready package.
