The sinsemilla bud that started flooding the market was much higher potency than the seedy, low-quality bud that had been available before. This led to the term sinsemilla being used to describe very high quality and potent cannabis. There’s no doubt that most growers prefer buds without seeds, but the term sinsemilla has led to the idea that cannabis buds without seeds were inherently more potent than seedy bud.
The curing process also has other benefits for marijuana growers. For example, cannabis buds that get dried too fast may smell like cut grass or hay, even if they smelled great in the flowering stage. The curing process helps get rid of the unpleasant grassy taste/smell and brings back the natural taste and smell of the cannabis plant.
Your plant genetics set the “upper limit” of how much THC and other cannabinoids your plant will ever be able to produce. Although you can use grow methods to maximize the THC within that limit, you will never be able to overcome the limits set by your strain and plant genetics.
These Mandarin Cookies buds were listed as producing 25% THC. They and produced about that under HID grow lights but tested at 27% THC under the HLG 300. Several other clones from the grow also tested at higher THC than expected. This was only one grow comparison but so far the HLG seems to be the most “THC-increasing” grow light I’ve tried.
My idea for a test (hopefully someday I’ll get to do this when I get more room to grow!)
Lack of Pollination (Producing “Sinsemilla”)
There are certain techniques that will definitely maximize the THC produced by your cannabis, and there are other methods which may increase potency but their effects are less certain.
In the vegetative stage, moderate humidity levels are necessary. Every week, you can decrease it by 5%. Around 40% to 70% will work. Given that the roots are stronger during this period, they can absorb more water, so lowered humidity levels are preferred. For the temperature, you can raise it a bit — around 71 to 82 degrees Fahrenheit during the day and around 64 degrees Fahrenheit to 75 degrees Fahrenheit at night.
Harvest time keeps growers excited, especially given all the efforts exerted to produce healthy and quality buds. However, cutting them too soon will defeat the purpose and waste all your hard work as the tetrahydrocannabinol (THC) content will be low. So, harvest them at the right time based on the following indications:
Reducing the humidity levels to 40% to 50% is needed during the flowering stage. You can make it 55% but never 60%. Also, the temperature can decrease to 68 to 78 degrees Fahrenheit. Then, in the latter part of the flowering period or one to two weeks prior to harvest, reduce humidity levels from 30% to 40%.
Meanwhile, the temperature can fall between 64 to 75 degrees Fahrenheit or 18 to 24 degrees Celsius with lights on and 16 to 20 degrees Celsius for several nights before harvest. To monitor the humidity and temperature, use a hygrometer and thermometer.
Nitrogen, potassium, and phosphorus may be the three main nutrients that your cannabis plants need. However, they also need other nutrients like:
Did you know that providing your marijuana plants with sufficient carbon dioxide (CO2) helps improve their growth by 20%? CO2 is crucial in photosynthesis, where cannabis absorbs light and turns it into energy. Excessive CO2 or a lack of it can be detrimental to your cannabis plants. So, you should know how to provide them with the right CO2 levels. Ideally, it should be above 250 PPM.
Enhancing humidity levels can be possible through the following:
If you aim to lower the temperature, you can do the following:
