If you want a better outcome for your marijuana harvest and grow bigger buds, there are some things you will need to consider, including identifying the marijuana plants being grown and knowing how you can increase that growth. We’ve assembled the top tips for growing and harvesting big cannabis buds.

Growing big marijuana buds is the goal of every cannabis grower. The flowering stage is the stage where the plant produces its trichome-rich buds. While the leaves do have a certain level of THC, the marijuana buds in the female plants have more potency by far.

So, if you grow individual marijuana plants, you should pay close attention and focus on the best environment for marijuana buds in your crop.

Steps to Take For Growing and Harvesting Bigger Marijuana Buds

Choose High-Yield Cannabis Strains

Starting with genetics that have proven to grow high-yields of dense and aromatic buds is the best way to grow big buds. While indicas tend to grow shorter and bushier than sativas, this isn’t always the case. Research strain growing information (height, yield size, etc.) of indica, sativa, and hybrid varieties before committing to a strain.

Research reputable seed vendors and consider the following factors to choose the right genetics:

  • Availability of seeds or clones
  • Desired effects of the flowers
  • Desired length of time from planting to harvest
  • Desired yield
  • Number of plants
  • Growing environment
  • Space requirements

For new growers, we recommend starting with one or two indica clones, since indicas are usually easier and faster to grow than sativas.

High-yielding strains include:

  • Bid Bud
  • Northern Lights
  • White Widow
  • Blue Dream
  • Cheese Quake
  • Purple Trainwreck
  • Critical Kush
  • Original Glue
  • Thai Stick
  • Super Silver Haze
  • Amnesia Haze

Grow Hydroponic Weed

Hydroponic cannabis grows can produce bigger yields than traditional grow systems. Many commercial growers rely on hydroponic systems like deep water culture (DWC), ebb and flow, and nutrient film technique (NFT), to grow bigger and better plants.

Generally, the idea of hydroponic systems is to provide plant roots with a nutrient-rich solution in a highly-oxygenated environment. Plant roots are supported by an inert medium like Rockwool or hydroton clay pebbles instead of soil. In this environment, plants can absorb nutrients and minerals more effectively.

Growing plants hydroponically can be difficult for first-time growers. However, as long you understand how to manage pH and provide plants with the right nutrient solution mix, you can grow big buds with minimal issues. A major aspect of having a successful hydroponic garden is the cleanliness of the environment to reduce the risk of disease.

Give Plants Plenty of Light

Cannabis plants thrive in a well-lit environment, which promotes photosynthesis. Choosing the best grow lights for your cannabis garden depends on various factors, including your budget, the grow space, the stage of life of the plant, and your desired yield. The size of your harvest will depend on the amount of light your plants receive.

Consider light placement to ensure maximum penetration throughout the canopy but also far enough away to avoid burning the plant. High-pressure sodium (HPS) lights are excellent for use during the flowering stage to grow bigger buds but they create more heat, increasing the risk of burning plants and requiring temperature control systems.

For HPS lights, consider these recommendations for HPS wattage and distance between lights and plants:

  • 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

Maintain Optimal Temperature and Humidity

Getting the temperature and humidity just right for your plants can make a big difference in yield, bud size, and trichome density. We recommend avoiding going over 80º F during the flowering phase.

For seedlings, temperature should be around 77º F during the day and 70º at night with a 65-80% humidity. During the vegetative stage, temperatures can range between 71-82º F in the day and 64-75º F at night with a 55-70% humidity.

In the early flowering stage, the plant thrives in temperatures between 68-78º F in the day and 61-72º F at night with 40-50% humidity. In the late flowering stage, keep the temperatures between 64-I’m 75º F in the day and 61-68º F at night with 30-40% humidity.

The excess humidity and heat can increase the risk of bud rot and evaporate the heat-sensitive, aromatic terpenes. Extra chilly temperatures can slow down bud growth and create wispy nugs.

Remove Male Plants

Before growing marijuana buds to get them bigger, you need to understand that buds developduring the flowering stage. Because the buds have a higher level of THC content, it is essential to get them as big as you can. However, there are some differences between the male and female plants, which you need to know too.

Female marijuana plants produce buds that have a higher level of THC than male plants. Male marijuana plants do not produce cannabis buds but can produce leaves and stems with minimal trichomes, and you can still smoke them.

Because the male buds have so much pollen, you have to be careful not to allow female plant pollination. If the female plant gets pollinated, then the marijuana plant will begin to produce seeds instead of buds and have a lower level of THC.

The marijuana buds of the female plant will start to show within two weeks after the buds of the male plant show up. You should focus your attention on the female buds as they are superior tomale pollen sacs.

Prune Cannabis Plant Leaves

Pruning can help your marijuana plant get rid of unnecessary foliage and focus on growing its most critical components.Start by getting rid of the dry leaves. Look for discoloration of the leaves so you know which ones to remove.

Even though you will remove those leaves, you don’t have to discard them, but you can keep the leaves for curing because the discolored leaves still have a sufficient level of THC content. You use them for recreational smoking while you wait for your bigger marijuana buds.

Train Your Marijuana Plants

Plant training allows you to manipulate how your cannabis plant grows. Plant training techniques range from low-stress training (LST) to high-stress techniques (HST). Plant training usually does not require expensive equipment or extensive training. Consider using LST and HST on your plant, including:

  • Super cropping
  • Screen of green (SCROG)
  • Topping
  • FIMing
  • Manifolding
  • Defoliation

For example, topping your female marijuana plants involves removing the top of the main stem of your vegetative plant. Topping a plant causes additional branches to grow and produce more buds. It also saves the plant energy and helps with pruning.

Use the Right Ratio of Nutrients

Another thing to consider is using the best nutrients for your marijuana plant throughout its vegetative and flowering stage. Nutrients should be chosen for each phase, the flowering phase. Be careful what nutrients you use during the flowering stage.

To get bigger marijuana buds, make sure the plant receives enough phosphorus, nitrogen, and potassium. Phosphorus is usually most of what your marijuana plant craves during this stage. To get enough phosphorus for your plant, you could mix water and wood ash and apply them to your plant.

Harvest During Peak Maturity of Trichomes

Growing big cannabis buds isn’t enough. Your buds need to have a high density of trichomes. In addition, the trichomes need to be at their peak maturity to provide you with the highest potency and best flavor and aroma.

There’s a short window where the plant’s trichomes turn from a clear to milky white and then amber. The best time to harvest cannabis buds is when most of the trichomes have turned amber.
