General Hydroponic KoolBloom Available as Liquid KoolBloom or Dry KoolBloom, this additive is widely regarded as the best bud hardener out there.
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.
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.
Paclobutrazol impacts a plant cell's ability to elongate, which in cannabis means cells pack much tighter and denser on the flower.
A bud hardener is an additive you can use at the end of the flower cycle to tighten up your flowers and pack on weight. They are typically used in the final 3 weeks or so of the grow cycle and contain a mix of macronutrients, micronutrients, minerals, essential oils, etc.
Topping to increase the number of colas
Prune to clear off dead leaves to help your plants focus their energy on the live parts of the plant. Prune large leaves which get in the way of light reaching the colas. Topping is a form of pruning and involves pruning off the branch tip of the main cola.
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.
Big Bud's specific ratios of phosphorus, potassium, magnesium and amino acids. This product's harvest-boosting power will significantly increase the weight, quality and density of your flowers and can be used with any feed program. Give it a try for heavier yields — that taste great!
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.
Buds not dried properly. Improper drying after harvest is the #1 reason for harsh weed. Buds may become harsh from drying unevenly, drying in poor conditions, or the formation of mold/bacteria/microrganisms (often you can smell it but can't see it).
Buds get less dense when it's too hot. Look at the loose structure of this bud grown in extreme heat. Another thing about temperature: cannabis plants in the flowering stage like it to be a little warm in the day, but cool at night. Warm nights are also associated with airy buds.
Instead, utilize organic fertilizers like worm castings, blood meal, fish meal, or bat guano for nitrogen; bone meal or rock dust for phosphorus; wood ash or kelp meal for potassium; and dolomite lime for calcium or magnesium.
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.
Weeks 4-6: Buds Fatten Up
At this stage of cannabis flowering, your buds are getting bigger. They'll still have all the white pistils sticking out, but you'll be able to see the buds getting bigger every day.
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.
While molasses can contribute to better soil quality and overall plant health, it is not a direct factor in increasing bud size or trichome production.
Molasses contains a huge array of crucial minerals needed for weed plants to survive and thrive. Alongside this massive benefit, it helps to bring the soil to life by feeding beneficial bacteria and fungi. This then enables plants to tap into even more nutrients already present in the soil.
Many sugar or carbohydrate-based supplements claim to improve the smell/taste/sweetness of buds. A cheap alternative to expensive sugar-based bloom boosting supplements is blackstrap molasses. Giving this to your plants for the last few weeks before harvest can help them get bigger and smell/taste better.
Most of the time, the bigger the buds, the better the quality, but each strain produces a different size and shape. Indicas tend to be more dense and smaller, while sativas are much less dense, fluffier, and generally regarded as less aesthetically pleasing. ...
Make sure to use a high-quality nutrient solution and follow the recommended feeding schedule for your plants. Also, maintaining the right temperature, humidity, and light levels in your grow space can significantly improve the size of your buds!
Cannabis plants need water and nutrients to grow and develop big, healthy flowers. Drought, overwatering, and over/underfeeding can all affect your plant's ability to develop big, dense, and heavy flowers.
It's important to maintain ideal temperatures for good flowering. Avoid Excess Wetness (Including Humidity) – Diseases (and many pests) thrive in wet environments. Don't let your buds sit around damp all day. And you don't want too much humidity during the flowering stage.
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.
Guideline #2: Harvest marijuana when 70% of the pistils have turned brown or orange. Most cultivators who base their harvest date on the Pistil Method take down their plants when 70% of the pistils have changed color and curled inward. If 90% of the pistils are brown/orange, the plant is past its peak.
