Heck, with good-quality soil, your plants may do just fine without additional nutes all the way to harvest. If you must add nutrients to the soil early on, do so sparingly. Generally, bloom nutrients and boosters are all that’s needed during their life cycle.
Even in flowering, low to medium doses of nutrients will suffice. Over-fertilising plants is a common yield-thwarting mistake autoflower growers often make. If the pH is off, your plants can’t uptake nutrients even if they are present. The correct pH for your water when growing in soil is 6.0–7.0. With a few drops of pH up or down products, you can adjust your water to the correct pH window. Seedlings and young plants prefer a more humid environment, while flowering plants require significantly less humidity to avoid mould and rot. At times, just a simple standing fan or leaving a window open is all that’s needed to create an optimal growing environment. If that doesn’t cut it, look into solutions such as a heater or air conditioner for your grow room. USE CO₂ It is scientifically proven that plants use CO₂ as fuel for photosynthesis, and with more CO₂ in your grow space, there should be a noticeable difference in growth rate and size.
The thing is, it only makes sense to provide your plants with CO₂ if all the other conditions in your grow room are already optimal. If there are issues with temperature, humidity, water, or nutrients, address these first before looking into a more elaborate (and expensive) CO₂ system. Low-stress training (LST) is a non-destructive training technique that even beginners can use. As the name implies, it is a minimally invasive technique that doesn’t involve any major damage to plants. All you do is carefully bend and tie down the stem and branches to encourage lateral growth. This way, more bud sites are exposed to your grow light, resulting in fatter nugs and bigger harvests. If you’re an expert grower and not afraid to put a knife to your plants, you can see whether topping will work for you. Just ensure that everything else is under control before looking into these more-involved plant training techniques. USE SEA OF GREEN (SOG) The sea of green, or SOG, method involves growing many small plants in close proximity to max out space and yields. This is especially effective in otherwise small grow-ops, and there is no better candidate than autoflowering strains. Their fast growth and short stature essentially do everything for you. It normally happens that the flowers at the top of the canopy mature faster than those at the bottom. Simply clip off the individual buds that are ready, and wait for the rest to ripen. Wait 1–2 weeks between each harvest and watch for signs that they're ready to pick. Most autoflowering plants only require two cycles of progressive harvesting, but larger plants may need more. To become an expert, you want to pay attention and carefully record each process used in your grow. Only this way will you notice which techniques render the best yields. Something can always go wrong when growing cannabis. The key to high yields is swiftly and smartly identifying problems as they occur. As you refine your processes, the health and yields of your plants will improve over time. THE TOP 5 HIGHEST YIELDING RQS AUTOFLOWERING STRAINS 2020. Perhaps more important than any other factor listed above, genetics have a huge influence on a given strain’s production potential. So, before we conclude our guide on achieving maximum yields with autoflowers, here is a list of the highest-yielding autoflowers from Royal Queen Seeds. Northern Light is a legendary cannabis strain that derives from Afghan indica genetics. First bred in the 1970s US, and coming to Europe in the 80s, this indica is still a favourite among many cannabis lovers.
The autoflowering variant Northern Light Automatic shines with all the goodies of the “big one”, without compromising on flavour and effect. Moreover, she is one of the highest-yielding autoflowers out there with a whopping 550g/m² indoors.
She pleases with a sweet, earthy pine flavour and a cerebral effect that is happy and uplifting. Autoflowering cannabis strains are popular for many reasons; they are fairly easy to grow, grow very fast, don’t depend on photoperiod, they remain relatively short and can deal pretty good with tougher conditions and colder weather.
