Cannabis Growing Environments – SOIL and pH Level. Cannabis can be grown in soil or soilless media. The optimal pH for healthy growth ranges between 5.9 and 6.5. The pH level needs to be controlled during farming. The perfect temperature during the day is 75°F to 86°F (24°C to 30°C). Higher or lower temperatures will reduce flowering rates and will have a damaging effect on yield and quality.
When growing hydroponically indoors, the duration of the growth stages could be controlled by changing the exposure of the crop to varying light intensities. When daylight time is between 16-24 hours per day, marijuana/cannabis nutrient recipes will undergo rapid vegetative growth. When daylight hours start to shorten, the plants goes faster to an indication of flowering.
When using artificial light, the sunshine intensity will have an effect on the total growth, growth duration, water management, and nutritional need for the cannabis plants.
The ultimate cannabis product is usually female-only without female pollination. To prevent male differentiation or crop variation, cannabis is normally planted as rooted cuttings. After having a short time for establishment (about 14 days from planting), the vegetative phase will start.
The vegetative phase lasts about 45 days, where time the plant requires a significant amount of light strength. Nutrient requirements are high, especially nitrogen, potassium and micronutrients.
The duration of the flowering stage varies among different species and can range from 50 to 140 days. This growth stage begins when the darkness photoperiod exceeds 10 hours. Throughout the flowering stage, the nutrient requirements of cannabis change too; the plant will require larger quantities of potassium and much less nitrogen (which encourages vegetative growth).
Nutrient Management – When growing hydroponically, optimal conditions may be maintained, to be able to achieve maximum yield potential at the very best quality. In hydroponic systems, fertilizers are offered to cannabis by making use of a nutrient solution, prepared based on its current nutrient requirements, growing conditions and nutrient content of the source water. We recommend to check the origin water periodically, in order to get the exact fertilizer formula which will meet the crop demand.
The key objective of crop nutrient management is to use the correct rates of nutrients in the perfect time, based on the dynamic conditions. Ideal results can be accomplished by adjusting the applied nutrient solution, based on the variations in the growing conditions, such as temperature, humidity, source water quality, pH, salinity (EC/TDS), the composition of the nutrient solution (especially if recycled). These parameters are really easy to monitor, and should be measure frequently.
Give Your Plants More Light – If you’re growing indoors, then so long as you give your plants a lot more than 14 hours of light every day, they’ll stay in the vegetative stage. But you can easily give them 24 hours of light on a daily basis and it’s like “forcing” more growth. (Keep close track of your plants though, when they seem to develop problems you might want to back to 18 hours of light to recoup).
Use The Best Nutrients – This really is one area you don’t wish to skimp! It’s important to use nutrients specifically designed for the growth/vegetative stage of your own plants (we’ll speak about which ones we recommend shortly, but the great thing is they’re even the best nutrients for newbies too).
Fractional Co2 – If you’re growing indoors, consider using Co2 because the more CO2 your plants have the more they are able to grow. Also, the greater CO2 they ingest the better light they are able to handle (meaning this works synergistically with tip #2).
Prune The Useless Bottom Shoots – As well as pruning sick leaves out of your plants, you need to try to find small, useless shoots involving the branches and also the trunk in the bottom of your plant. Should you remove these, then more energy will be designed for the colas leaving on top of the plant to direct towards growing bigger and getting yourself ready for a great harvest.
Measuring the dynamic parameters is essential as well as simple to perform. The key challenge in nutrient management, would be to translate the data into actionable actions, which will improve the yields and quality. For this particular, growers fwacgp a certain recommendation system, a decision support tool which will help them have the right decisions, based upon all factors affecting cannabis growth.
One important point though is definitely the distinction between growing indoors and outdoors. Put simply, where and how you grow is equally as important as the strain you start with. For instance, regardless of what genetic strain you start out with, if you’re growing indoors, and also you don’t have a high ceiling and meticulously managed grow room, then you’re not getting as big of plants indoors as you would outdoors.
That’s because it’s important to recognize that plants need space so that you can maximize size. It can be stated that the larger the space to grow the bigger the plant. One area where plants definitely need plenty of space is for their roots. Now, with hydroponics like Deep Water Culture or another pure hydroponics system, you will get away with smaller roots because of the increased feeding efficiency, yet still, bigger space equals bigger plants things considered.
