Really nice purple buds with a taste of berry and wood/earth.


Fruity yet sour flavor with a diesel-like aftertaste.


Some strains taste better one way, some the other – this is a smoking strain.

The high hits immediately and lasts quite a while but it can produce a pretty wicked case of the munchies so be prepared for that.


Tastes good and sugary. Makes me laugh 100% of the times I smoke for no reasons. Energetic and mood enhancing.


Definitely more of a body high, but not overwhelmingly couch-locky or anything. The second one smokes the same but definitely stronger and a mix of body and head vs the first one.

LSD-25 Auto Seed-to-Harvest Time

The life cycle of LSD-25 Auto spans a range from 8 to 16 weeks, averaging at 10.4 weeks. Around 25% of growers reported a 10-week cycle, making it the most common duration. Less than a third of growers experienced cycles shorter than 10 weeks, while over half needed more time. The vegetative stage typically lasted four weeks, with more growers having shorter vegetative phases than extended ones.

For outdoor cultivation, data from 19 grows suggests an average cycle duration of 10.8 weeks. Despite the limited sample, LSD-25 Auto maintains its versatility outdoors, reflecting the adaptability observed in indoor environments.

Delving into the influence of mediums and training techniques on cycle duration, the data reveals no clear trends, all being remarkably alike in contrast to most other strains. Enthusiasts can explore detailed charts above for a comprehensive understanding of how different variables impact (or rather don’t impact) LSD-25 Auto’s cultivation journey.

LSD-25 Auto Flowering Time

LSD-25 Auto’s flowering time exhibits a considerable range, as evidenced by data collected from various grows spanning 4 to 16 weeks, with an average of approximately 6.4 weeks. The most prevalent flowering duration falls within the 5 to 6-week range, indicating a relatively consistent pattern among growers. However, it’s essential to note that the outdoor cultivation sample is limited, comprising only 19 grows, where the average flowering time extends to 7 weeks.

LSD-25 Auto Height

Based on available data, LSD-25 Auto tends to reach an average height of around 62 cm by harvest time, with a slightly elevated average of 67 cm observed in the 15 outdoor grows for which there is data. This suggests that, whether cultivated indoors or outdoors, LSD-25 Auto maintains a relatively compact stature.

Exploring the impact of growing conditions on plant height reveals interesting insights. Unsurprisingly, plants that received no training generally exhibited greater height. Low-stress training emerged as the most consistent technique for controlling canopy height, while the outcomes of topping varied a bit more but the technique was nevertheless more effective than in many other autoflowers.

Further analysis of cultivation mediums highlights nuanced differences in plant height. On average, plants tended to be smaller in soil grows, slightly taller in coco coir, and still taller in hydroponic setups. Unexpectedly, the relationship between pot size and plant height at harvest lacked clear patterns. While a general upward trend in height was observed with larger pots, the chart above suggests that using a container bigger than 20 liters would be a waste.

LSD-25 Auto Yield

When assessing LSD-25 Auto’s productivity, per-plant yields varied significantly across different grows, ranging from 9 to 373 grams after an average cultivation period of approximately 10.4 weeks from seed. The typical per-plant yield settled around 61 grams, offering a benchmark for growers aiming for a consistent outcome.

Examining the impact of growing mediums on yield, hydroponic grows led the pack with an average of 90 grams, followed closely by coco grows at 82 grams, while soil grows produced a slightly lower average at 57 grams.

The type of training employed further shaped yield outcomes. Untreated plants yielded mixed results, showcasing the potential for both low and high yields, indicating that other factors played pivotal roles. Growers employing low-stress training methods achieved yields around the average, albeit with notable variations, while topped or FIMed plants consistently produced above-average yields, suggesting a more reliable outcome with these techniques.

Cultivating LSD-25 Auto outdoors resulted in an average yield of 27 grams across the 19 available grows, reinforcing the strain’s adaptability across diverse cultivation environments.
