How to Significantly Boost Cannabis Yields Indoors

An in-depth guide that focuses on boosting your cannabis yield with a few tried-and-true techniques.

How to Significantly Boost Cannabis Yields Indoors Cover PhotoMost indoor cannabis cultivators have one goal in mind — to produce scale-busting yields.

Although we believe in quality over quantity — there’s nothing like watching over a sea of huge buds swaying in the breeze. However, fattening up buds before harvest is an art that few master during their tenure as a weed grower.

Read along to learn how to boost marijuana yields indoors significantly. You’ll discover tried-and-true techniques that’ll make buds bigger during flowering — guaranteed.

Get your plant supports ready — your buds are about to look like they’re on steroids after you finish this guide!

Choose The Right Genetics For Massive Yields

The foundation of any high-yielding indoor cannabis garden is the right genetics.

Although you can fatten up your buds with any of the tips in this guide — buying high-yielding autoflowering or feminized strains is paramount.

Many cannabis strains are geared towards commercial production, which we’ve already detailed in our guide — The Best High Yielding Cannabis Seeds. However, home-based cannabis cultivators can take advantage of these high-yielding weed strains too!

Ultimately, picking a high-yielding marijuana strain is the first step to produce big buds indoors. There are, however, many other variables that determine the final yield of your weed garden.

Let’s continue!

Support Your Weed Plants

Sometimes, your cannabis plant needs a helping hand.

As your marijuana plants begin to flower, the weight may become a burden to the branches or stems that support it. In the natural world — cannabis flowers aren’t known to get big due to the pollination process.

However, indoor cannabis cultivators skip the fertilization process (females only in the grow room) — thus creating huge weed flowers.

By adding supports early on during the vegetative process, you can easily support your weed plants once the flowering stage begins.

Suddenly, your marijuana crop doesn’t need to focus energy on supporting itself. In turn, the buds will grow into dense flowers that are riddled with resin glands.

Train Your Cannabis Plants

Are you familiar with cannabis training techniques?

If not, head over to our guide — The Encyclopedia of Cannabis Training Methods to learn about a wide variety of marijuana plant training methods.

From the sea of green method to topping — training your weed plants is a sure-fire way to get bigger buds during the flowering stage.

The basis of training your marijuana plants during the vegetative phase is to set the stage for:

  • An even plant canopy
  • Multiple bud sites
  • Increased light penetration

Overall, training your weed plants is an easy way to boost any indoor marijuana strain’s final yield.

Bump Up The Lumens

One of the most significant factors in bud production is light intensity.

As photosynthesis occurs, a biological process produces energy for a myriad of functions throughout the cannabis plant. As you can imagine — marijuana plants require an abundance of energy to grow big buds.

You don’t need a 1,000-watt HID to yield huge buds (although they help), thankfully, since LEDs, T5s, and CFLs provide adequate light. Therefore, you can enhance the light intensity by moving your grow lights higher or lower — depending on your weed plants’ size.

Here are a few ways to bump up the lumens to stack on extra weight during the flowering process:

  • Lower the grow lights
  • Select the “boost” option on your grow light system
  • Add supplemental lighting
  • Increase reflectivity within the grow room (mylar/flat white paint)

Unsure how to install or position your grow lights for maximum exposure? Learn how by reading our guides — How to Hang Cannabis Grow Lights and How to Set The Perfect Height For Your Cannabis Grow Lights.

Furthermore, ensuring your grow light timer functions properly is paramount to your overall success. Therefore, we recommend that you read our guide — How to Set Up a Cannabis Grow Light Timer to ensure your buds experience a steady 12/12 flowering schedule.

Get Your Climate In Check

Environmental factors play a massive role during the flowering process indoors.

As you may be well aware — indoor cannabis gardens require artificial light. In other words, power-hungry HIDs or environmentally-friendly LEDs. In either case — light produces heat.

However, there are elements other than temperature that’ll hamstring bud growth if you fail to consider, such as:

  • Humidity
  • Airflow

Here’s an essential checklist when making your rounds on your indoor cannabis garden. As long as these values are within the allowed range — your buds will stack on the ounces!

  • 72-85°F
  • 35-60% RH

One of the primary methods to regulate the temperature and humidity within the indoor grow room is with a ventilation system. If you’d like to learn about ventilation systems, head over to our guides — How to Plan an Indoor Cannabis Garden and read step seven.

Although marijuana plants are called weeds for a reason — the biggest yields come from happy and healthy plants!

Break Out The Bud Booster

Once the flowering stage kicks in — your weed plants will have a ferocious appetite. Cannabis plants get a sudden urge for more phosphorus and potassium, in particular, once flowering begins.

Whether you’re growing weed in organic soil or full-blown hydroponics — apply a dose of bud booster! A well-timed “shot” of bloom booster will turn lackluster buds into full-fledged monster flowers.

However, you must be careful as bloom boosters are highly concentrated and may burn your cannabis plants. Remember — a little bud booster goes a long way.

Prune Your Green Beauties

Cannabis plants are incredibly responsive.

As you cut off vegetative growth, the marijuana responds by reverting energy from cut branches and leaves towards healthy growth.

As cannabis plants grow, it’s natural that the uppermost leaves cover lower leaves. In other words, the lowest growth does not receive ample light.

Here’s what happens when you don’t prune your cannabis plants:

  • Fluffy buds
  • Reduced yield
  • Small flowers

Alternatively, here’s what happens when you do prune your marijuana plants:

  • Increased yield
  • Dense flowers
  • Massive flowers

Therefore, pruning your marijuana plants is a tried-and-true method to increase flower size across the upper-most canopy.

Massive Yields Await Those With Patience

Last but certainly not least is to allow the cannabis plant to complete its full flowering process.

Unless it’s an emergency — never harvest your weed plants until the trichomes are ripe. Cannabis flowers continue to grow until ripe, which means you’ll miss out on a lot of weed if you fail to show a bit of patience.

If you’ve never harvested cannabis or you need to brush up on your skills, read our guide — How to Check Trichome Ripeness (Coming Soon) to learn more!

By being patient — you’ll experience the full potential of your weed plant’s yield.

Get Your Trimming Scissors Ready For A Scale-Tipping Harvest

As long as you consider all of these yield-increasing tips — your cannabis garden will be flush with trichome-covered flowers.

From bottle-sized buds to scale-tipping weight — you’ll be floored by how much weed your indoor garden is capable of yielding.

Whether you grow small cannabis plants or marijuana trees — you’ll be shocked by heavy buds that get bigger each day during the flowering stage.

However, with great yield comes great responsibility. If you’re ready to do your weed justice — read our How to Harvest Cannabis Flowers and manicure them to perfection!
