Increasing the amount of CO₂ in your grow room can help you grow bigger, denser buds. By doing so, you'll help plants photosynthesise faster and encourage them to take up more nutrients and water.
Paclobutrazol impacts a plant cell's ability to elongate, which in cannabis means cells pack much tighter and denser on the flower.
Lack of light is perhaps the most common reason that cannabis produces fluffy, light buds. You may have noticed the lower, puny 'popcorn' bud sites that form below the main canopy. Often these buds are discarded by growers allowing the plant to focus biochemical energy on the main blooms.
Dense/Fluffy
These flowers simply hold more mass, look much healthier, and smoke smoother. Grinding up dense cannabis flowers seems to almost double their size. Even a small chunk of a compact flower can grind down to fill a good-sized joint. In contrast, fluffy buds yield disappointment and less plant matter.
Molasses adds sugars to the plant and will help it to bud. Like us, plants need salts, nutrients, and sugars daily. Feeding your plants molasses, what could be considered the equivalent to our eating junk food sugars, will pack on the weight to your marijuana buds.
High quality buds will be dense and thick, having grown to a heavy weight during the flowering period of the plant's life cycle. These dense buds signal that the plant received adequate nutrients and light throughout its lifecycle, resulting in a flower rich in cannabinoids and terpenes.
Allowing the roots to have the space needed to fully develop. It will also keep the plants from locking out the oxygen they need. Overwatering can also cause buds to become loose and fluffy. When the soil or grow medium has too much water, oxygen cannot reach the roots.
The last three weeks is when your buds can actually gain the most weight – that is if you feed them Overdrive®. After your peak bloom phase, your plants enter their late bloom phase (the precise timing and length of which depends on the strain of cannabis you're growing).
Potassium makes the plant hardier and stronger, better able to withstand hardship or disease. All of these are vital for growing large marijuana buds, but you have to use them wisely. Sulfur is another nutrient that, like potassium, helps the plant absorb other nutrients and water.
After a sugar application, the resulting sugar-like crystals are the flower's trichomes, which are believed to double in production after the plant is treated with sugar.
Weak Light Source: On a similar note to distant lights, a weak light source can cause unnecessary stretching and growth in your plants. A light bulb that does not emit the necessary watts and lumens for your specific growth stage can force plants to grow tall and skinny in order to absorb the weak light.
Loose, sponge-like flowers can be highly disappointing. Caused by a combination of poor genetics, inadequate nutrients, swings in temperature/humidity, insufficient lighting, and stress, loose buds are hardly worth harvesting. Soft, fluffy flowers can also be deceiving.
High Heat and/or Humidity
Heat and humidity can encourage plants to develop airy, wispy buds in an effort to fend off mould and other pathogens/pests.
Environmental Factors are Important for the Cannabis Plant
Another reason that a cannabis plant may have small buds is due to environmental factors. If the plant is not getting enough light, it will stretch out in search of more. This can lead to a large plant, but small buds that are spread out along the stem.
When the flushing process has reached the fan leaves, they will begin to yellow and turn lighter as they send the stored nutrients to the flowers. The flowers will fatten up during these last few weeks while flushing; this can be up to 25 percent of the final weight.
You will know that your plant is ready to be harvested when the colors of the pistils on cola buds turn from white to reddish orange and the trichome heads turn from transparent to milky to opaque and finally amber. The amber color indicates a higher CBD to THC cannabinoid ratio in its resin.
Godfather OG is quite possibly the highest THC strain. Labs put the strain's THC levels at a tremendous 30-35%. In fact, Godfather OG is touted as the world's strongest marijuana strain. This potent strain is an Indica-dominant hybrid and hits within minutes of taking the first smoke.
As previously stated, moderate levels of nitrogen and phosphorus work best to sustain trichome growth to the maximum level. Dumping nutrients on your plant during the second half of the flowering cycle can result in reduced cannabinoid and terpene content, thereby lowering your bud quality in both flavor and potency.
During flowering, switch the lighting schedule to 12 hours on and 12 hours off. The key for maximum yields is to provide large amounts of light and to distribute it as evenly as possible across the canopy. Space your lights accordingly.
Are Small Buds more Potent? Small buds are generally the same potency as large nugs of the same strain. Small nugs come from the same plants as large nugs, they're simply pieces of flower that tended to get less light and thus didn't grow as large.
Bud structure
High quality, developed flower from a healthy plant has a sturdy, fully three-dimensional structure. The buds should be solid, with no gaps that you can look through. It's properly cured: not too soft, but not so dry that it grinds down to dust. Flower with poor structure will appear flimsy and flat.
