The Evolution of Autoflowers. From Ruderalis to Modern Powerhouse Strains | Grow Guides Ep. 87
In this week’s Grow Guides, episode 87, we take a deep dive into the evolution of autoflowering cannabis plants! From its some what "humble" beginnings to the high-quality genetics we see today.
We start with ruderalis and the origins of autoflowers, explaining how this unique subspecies made automatic flowering possible in the first place. Then we move into the early days of auto breeding, including the Lowryder era, where the first true autoflower strains began to emerge. From there, we explore the turning point in autoflower breeding, when dedicated breeders began refining genetics, improving quality, and changing how growers viewed autos altogether.
We also cover modern must-try autoflower strains, highlighting how far things have come in terms of potency, flavour, yield, and overall performance.
Finally, we tackle the big question: are autoflowers now as good as photoperiods? We break down the pros, cons, and where autos truly stand in today’s growing scene.
A great episode for anyone curious about autoflowers, whether you’ve avoided them in the past or are already a fan of these fast-evolving genetics.

How to Prevent Grow Room Disasters, Heat, Pests, Mold, Power Cuts & Costly Mistakes | Grow Guides Ep. 86
In this week’s Grow Guides, episode 86, we focus on one of the most important topics for any home grower, preventing disasters before they happen.
We break down the biggest risks growers face, starting with heatwaves and temperature spikes, and how quickly things can go wrong if your environment isn’t under control. We also cover power cuts and equipment failures, and why having a plan in place can be the difference between saving your crop and losing everything.
We dive into pest prevention, explaining why stopping infestations before they start is far easier than trying to fix them later. From there, we cover mold and bud rot, including the conditions that cause them and how to avoid them completely. We also talk about overwatering and root zone issues, one of the most common mistakes growers make, and how it quietly damages plant health over time. And finally, we tackle the biggest cause of problems in any grow room, human error. Along with the importance of good habits, clean setups, and proper grow room hygiene.
This episode is all about staying one step ahead, avoiding costly mistakes, and keeping your grow running smoothly from start to finish.
