Yield is a significant factor for cannabis growers, especially commercial ones. By following our tips you can learn to grow like a professional and produce some of the highest yield autoflower strains. While autoflowers produce fewer yields compared to photoperiod strains, they make up for it by growing fast enough to provide multiple harvests within a year. 

An equally vital factor is quality. So how does a cultivator ensure that their autoflower harvest is massive without compromising overall quality (potency, terpenes, and visual appeal)? The answer could fill a book; however, this piece comprehensively sums everything via the ten tips on how to grow highest yielding autoflowers;

Before we start, have you purchased your high yield autoflowering seeds? Genetics are vital in ensuring a bountiful harvest. Specific high yielding autoflowers like Big Bud Autoflower and Tangerine Dream Autoflower are genetically engineered to meet the needs of cultivators looking for above-average results. Let’s begin 

Tip 1: Be prepared before starting the germination process

Autos grow within a record time of 8-12 weeks. Within 3-4 weeks after germination, they automatically transition into the flowering stage. There will be no time to start preparing for anything once you initiate the cultivation journey. The key to a successful process is preparing beforehand because, trust this, the plants won’t give you time to do so. 

Ensure you have set up the grow space, selected the grow medium, have the necessary nutrients, bought appropriate grow lights, and worked on the ventilation. If any of these is not set up, then you are not ready. Always remember that once the seeds sprout, you are in for a ride. 

Tip 2: Everything you need to know about utilizing growing mediums and pots for positive outcomes

First, it is essential to know that autoflower cannabis plants don’t react positively to repotting/transplants. Their ability to grow fast prevents them from recovering and adapting to a new growing medium. A grower needs to find a container/pot that they can use throughout the auto’s growth. A stable environment fosters excellent root development. 

The pot/containers should not be small as they will stunt the plant’s growth. Additionally, an oversized container leads to a waste of substrates and nutrients. To grow a high yield autoflower the ideal pot size should be containers with a capacity between 15 and 20 liters. 

Autoflowers thrive in a well-aerated grow medium. You can achieve this by avoiding compact substrates or by blending a growing medium like soil with coco coir or perlite. Also, having drainage-friendly pots goes a long way towards promoting root and overall plant health. 

Tip 3: Focus on root development

Healthy roots equal healthy plants. Mycorrhizal fungi are beneficial fungi that help promote better and faster absorption of water and nutrients in the roots. A balanced diet of nutrients for the plants leads to optimal growth, resilience, and improved resistance to common issues like diseases that affect cannabis plants. 

Tip 4: Pick an ideal autoflower light schedule

Autoflowers yield increases exponentially when the plants are exposed to sufficient light. To really get the most from your high yield autoflower seeds you need to provide a controlled environment, an 18/6 or 20/4 light cycle is recommended. This gives the plant enough time to make enough food for its optimum growth and get a well-deserved rest of 6 hours. There are other light schedules like 20/4, 24/0, and 12/12, but the 18/6 is considered the best. 

In an open environment, the summer weather leads to impressive harvests. Light from the sun is more powerful than any artificial light on the market. Even though the plants get about 12 hours of sunlight, the growth and yield remain uncompromised. 

Tip 5: Mind the nutrients

Due to their small size, autoflowers require less ‘food’ aka nutrients, than photoperiod plants. Always use half or a quarter of the recommended macro or micronutrient dose and then observe the plant’s reaction. You can increase the amount of nutrients gradually until the ideal outcome is achieved. A dose that exceeds the plant’s need leads to nutrient burn, which negatively affects the overall yield. 

Tip 6: Don’t forget about the PH

pH is incredibly important, even more so with autos because there is less time to correct mistakes. A low PH prevents the roots of the autos from absorbing vital nutrients like magnesium and calcium despite them being available. A higher-than-average PH leads to iron deficiency since it hinders the absorption of the element. Autoflower plant thrives in an environment where the PH of the growing medium ranges between 5.5 to 6.5 so keep monitoring your pH levels if you want to grow high yield autoflowers. 

Tip 7: Are your plants subjected to an ideal climate and sufficient CO2?

Autoflowers are naturally resilient thanks to the Ruderalis genetics. However, subjecting these plants to optimal conditions improves their health, development, and ultimately, yield. Seedlings and young auto plants (up to 4 weeks) require high but reasonable humidity (60% to 70%). To produce some really high yield autoflowers, you must get the climate right. When the plant enters the vegetative phase, you should lower humidity to 40% to 50%. The drop in humidity levels keeps the auto plants safe from bud rot and mold. 

When plants receive sufficient light, they can utilize the available CO2 to make the food they require to grow through photosynthesis. When the plant’s health dwindles, it may be due to a myriad of reasons. If it happens that the plant is receiving insufficient CO2, then the next course of action is investing in a CO2 system (this scenario is highly unlikely). 

Tip 8: Cannabis plant training techniques

As mentioned several times, auto plants do not have time to fully recover from any hitches that occur throughout their growth journey. If you are interested in implementing some training techniques as a grower, avoid HST as it is very invasive and destructive to the plant and best reserved for photoperiods. Try LST since it is non-damaging to the plant and a proven method of fostering good harvests. LST facilitates the equal distribution of light by triggering lateral growth. 

By using LST to grow the highest yielding autoflowers, you will encourage the plant to grow with a wider canopy which increases the number of bud sites whilst also allowing the plant to absorb more light, hence increasing photosynthesis.

Tip 9: Incorporate SOG method

The Sea OF Green is a perfect training method for growing high yield autoflowers, the technique involves placing multiple plants per square foot and a brief vegetative phase. The plant’s proximity helps utilize the grow space, speeds the growth process, and promotes higher yields. Autos are an excellent choice for this technique due to their fast-growing attribute and compact size. 

Tip 10: Keep a record of everything you do and any techniques you try

This final tip is how master cultivators are born. As growers gain experience growing autos and cannabis in general, they quickly determine what works and what doesn’t. By implementing what works and discarding what doesn’t in the next batch of autos, the novice grower quickly becomes a pro in cultivating high yield autoflowers.

Take away

Having top-notch high yield autoflower seeds is the first step towards having that bountiful harvest you have been yearning for. The second step is incorporating the tips given above, and the last one is learning and re-learning what works and what doesn’t. Soon, growing the highest yielding autoflowers will be your area of specialization.
