How To Grow Huge Marijuana Buds

With the restrictions on how many cannabis plants one can grow one might be wondering how to grow huge marijuana buds. In other words, this is called “maximizing the harvest.” But is this really possible with cannabis?

Here is a brief guide on how to go about creating chunky marijuana buds without incurring many costs.

Huge buds are the dream of every cannabis grower and this is how to do it!

1.  Select the Best Genetics

Selecting quality cannabis genetics at the beginning is a vital step because quality seeds are needed to produce huge marijuana buds. Look for high yielding cannabis strains; indicas will not disappoint. Generally, most indica strains will take a short time to mature and will produce huge buds if optimum growing conditions are maintained. Northern Lights, Black Domina, and Super Skunk are good for a start.

Get your seeds from a legitimate seed company for the best results.

2. Give Sufficient Light

Sufficient light ensures that you get high yields and fat marijuana buds. To increase the light energy reaching the plants, position the lights at a good angle facing the plants. Be mindful so as not to bring the lights excessively close, since it can destroy the leaves of the plant.

During the flowering stage, experienced cultivators recommend using the high-pressure sodium (HPS) lights because they help in growing huge buds from the plants.

The ideal distance that you should have between the plants and the light depends on the wattage of the bulbs. Check the guidance manual below for the ideal qualities.

While utilizing HPS lights, the table underneath can fill in as a guide.


Wattage Distance
150 watts 8-12 inches
250 watts 10-14 inches
400 watts 12-19 inches
600 watts 14-25 inches
1000 watts 16-31 inches


3. Ensure Good Plant Nutrient Requirements

During the flowering stage, aim to reduce the amount of nitrogen supplied to the cannabis plants and amp the phosphorus levels.

Nitrogen is associated with the robust vegetative stage of development, so the plants won’t require it to create thick colas. However, phosphorus empowers bud creation, which is the reason why flowering composts contain elevated levels.

The organic way is also an ideal way of ensuring good nutrients for the plant, chicken manure is the best source of phosphorous. To use it well, sprinkle it over the soil as topdressing.

4. Watch Out For the pH Level

The pH level plays a critical part in nutrient retention. Marijuana plants thrive well in an acidic root climate of pH 5.5- 6.5.

If the pH lies outside of this reach, the roots will struggle to catch the basic minerals required for ideal development.

Constantly check and change the pH each time you water and feed the plants.

5. Prune the Correct Way

You need to prune away the parts of the plant not getting enough light, for example, the lower buds and dead leaves. Eliminating them ensures that all the energy goes to the primary colas, permitting them to become the ideal huge, powerful marijuana buds.

Make sure to prune just during the vegetative stage since the plants may require time to start maturing well after the pruning.

6. Proper Training of the Plants

Commonly, cannabis plants grow with one stem being bigger than the other stems. Since the bigger stem overshadows the others, it will catch the most light and the lower branches won’t develop because they won’t get any light.

Training the cannabis plants ensures that you end up getting a plant with the same-sized stalks rather than a solitary huge stem. The important thing about training is that the whole plant ends up having uniform light access.

There are various approaches to go about this. The most famous ones are low-stress training (LST), and the high-stress training (HST).

Low-Stress Training

This strategy includes bending of stems and securing them in place. This is done by bending tall stems down and away from the center of the plant while it’s growing so that the plant takes a wide shape. Doing so improves energy productivity and guarantees an even light conveyance over the whole plant.

High-Stress Training

This method involves changing and manipulating the growth structure of the plant for example by folding the stems. When flexible enough, you could then control the plants to grow a specific way. This process ensures that you end up having enough yield from the plant.

7. Keep up Ideal Temperature and Humidity Levels

The correct temperature in the flowering stage is the key to getting huge and gigantic marijuana buds.

Check the table below for the required temperature and humidity levels in the growth stages.


Growth Stage Temperature (During Lights on) Temperature (During Lights off) Humidity
Seedlings Around 77°F (25°C) Around 70°F (21°C) 65-80%
Vegetative 71–82°F (22–28°C) 64–75°F (18–24°C) 55-70%
Early Flowering 68–78°F (20–26°C) 61-72°F (16-22°C) 40-5%
Late Flowering** 64–75°F (18–24°C) 61-68°F (16-20°C) 30-40%


Never surpass 80°F (26°C) during the flowering stage. That is because unnecessary warmth could slow bud development and debase the terpenes, bringing about the diminished smell, and flavors. On the other hand, too cold temperatures could make the buds to grow loose and light which would result in low yields.

Ensure that the temperature contrasts between lights on and off (or among day and night) are not very high. Ideally, choose 5-10°C to be safe.

8. Increase the Carbon Dioxide Levels

Cannabis growing, like any other plants, need carbon dioxide plus light energy for photosynthesis. Always remember that the more carbon dioxide than the better yields for you.

You can decide to add more carbon dioxide levels in the room by using CO2 tanks. Ensuring the grow room is well ventilated can help bring in natural air while removing old air.

The room should have enough light intensity so that photosynthesis can take place well. By having a legitimate ventilation framework, you ought not to have any issues.

9. Collecting at the Right Time

Harvesting at the right time is the way to collecting enormous, trichome-covered marijuana buds. You will need a magnifying glass to observe the trichomes. At first, the resin glands will seem clear however you should stand by until they turn smooth white, a pointer that the buds are ready before collection.

The nine tips discussed above are a good pointer to help you grow huge marijuana buds.

Happy growing!
