Some country's have regulations around weed, This is why some growers will put a number there within the limits. The photoperiodic plants can produce more than autoflowers because you are able to tell when the plant should go in flowering, also if you stress her the recovery time you can decide yourself. On autoflowers your limited after 4-5 weeks of growing she will go into flowering no mather the light-schedule she is on. - Therefore the period for failure / recovery is limited. Besides, if we take all of the factors away that we can control. The seeds quality can be limited, the DNA of the plant can decide she wants to do this etc. Unfortunately we cannot select a strain up front that will guarantee you the outcome. All we can do is motivate the ladies and keep track of what is working ;) To a happy grow !

You can make a photoperiod go into flower as soon as any autoflower does on its own... the only difference is choice in the matter. try looking at other diaries... you didn't look hard enough. Size of plant should be about what works for that grower. If i didn't want to breed plants, i'd be growing a sea of green instead of plants with a 2'x2' canopy. I wouldn't need 30-35+ days of vege phase to ensure i had plenty of cloning opportunities. I'd be sending a greater quantity of smaller plants into flower as faster than a typical autoflower with a 2-3 week shorter vege phase. I'd also have to scale up my vege area, which might mitigate most of the cost-savings from that, lol... so.. it's a matter of context and it can get complicated.

A lot depends on whether it's automatic or photoperiod; with photoperiod, there is not as much of a need to push "hard" as the real countdown only begins once the flower is initiated. Automatics, on the other hand, the chronological "clock" begins ticking the moment the seed germinates. It is of critical importance that the seedling growth gets off to the races, understanding that early growth is like compound interest, which will pay off come harvest. This reality is why getting autoflowers "off to the races" early on yields such exponential benefits. The "compound interest" is directly related to the surface area of the leaves. Larger, faster-growing seedlings process more light and build bigger root networks early on, which translates into an explosion of vertical and lateral growth during their short vegetative window. The margins for error are so thin with autoflowers; this early-stage momentum depends on several critical practices. E=MC2 looks like a simple multiplication problem; it describes a fundamental physical truth: mass and energy are the same thing. The equation doesn't just calculate a value; it reveals that mass is effectively "congealed" energy. Energy is just numbers. Energy isn't a physical "substance" you can hold or touch. It is essentially an abstract, calculated number that we assign to a system to predict how it will change, interact, or move. A numerical label we attach to matter to track how it behaves. Because the universe runs on laws of symmetry (specifically, that the laws of physics don't change over time), a single global number must be conserved. We call that number "energy". We don't grow shit; we facilitate the energy conversion. The rate at which any plant grows is essentially down to how much knowledge one can acquire to increase the level of conversion to occur. Applying knowledge effectively requires intuition, which comes from hands-on experience. A seasoned stoner learns to read subtle signs—like a slight change in leaf turgor (stiffness), subtle color shifts, or the specific texture of the soil—before a textbook diagnosis can be made. Ultimately, growing is the application of botanical science blended with active observation. Knowledge dictates your potential, but adaptability and attentiveness to the plant's immediate environment determine your results. Ofc genetics plays its role too.

Could be many factors why some have got low yields with photoperiod. But in general photoperiod plants are way better to grow then auto's. With auto's you really need to hit the ground running and have few issues to get them to out perform a photoperiod. The pre determined life cycle of an auto just is not forgiving. I'd only grown photoperiod before I joined this site and only found this site because I wanted to try some auto's, and I was really shocked at how hard it was to get into a half decent rhythm growing them. For me photoperiod will always be king and auto's do have there place, eg my outdoor gorilla grows are always auto's because photoperiod plants won't finish in time before the shift in weather. At least the diaries you looked at are honest with the yield, iv seen diaries claim to be massive yields but when I look at the plants I think bullshit.

With more than 100k diaries you just didn’t found the best growth ….

If that is all they are getting from a photoperiod plant (unless they have intentionally kept them small due to space limitations) then they are doing something very wrong! 4 and a bit pounds dried is my record for an outdoor photoperiod plant.

They need to start groing fastbuds, then 16g flower would be 100g (16g flower plus 84g nanners). Fastbuds4life! /proud cock weed smoker!

That's a good question, but the low yields in some grow diaries are usually not due to the plant's genetics, but rather the conditions set by the respective growers. Photoperiod plants theoretically have a much higher yield potential because you can control their growth phase (Veggie), but many home growers send their plants into flowering very early, use small pots, or grow with weak lights in tight spaces. Additionally, factors like proper watering, nutrient supply, and training techniques like topping or LST play a huge role in the final outcome. Another point is that the genetics of autoflowers have improved dramatically in recent years, so the difference under optimal conditions isn't as significant anymore, while mistakes with photos during a short veggie phase can greatly reduce yield. In the end, the harvest amount almost always depends directly on the setup and the grower's experience, not just on whether it's a photo or auto. Happy Growing Growmie🌱
