10 Marijuana Growing Tips to Maximize Your Harvest Day!

By now, you’ve probably heard a lot about the benefits of switching over to LED lights and other tips on growing marijuana indoors.

So you know just how important the lights are!

While the initial costs may be a little more than you were hoping, especially when you’re first starting to grow, you can’t beat the efficiency and results you’ll get from an LED system.

LED systems perfectly duplicate the spectrum of light your plants would receive from the sun.

While other light systems simply blast your cannabis plants with bright lights at maximum strengths, LED lights will work much more efficiently.

For example, take a look at our article comparing LED vs HPS grow lights.

They’re composed of a large number of diodes – some white, some infrared, and some ultraviolet.

The sun naturally provides infrared and ultraviolet, and this is what causes outdoor plants to grow so lusciously.m

Indoors, under lights that don’t duplicate those conditions, your plants are being seriously deprived of the light wavelengths that will ultimately maximize their growth.

You’ll see much larger yields because of the LED lights, and it’s hard to deny the reality of that when you’re weighing your harvest.

LED lights are also excellent for temperature control. Other lights emit a lot of heat.

Since their power doesn’t come from the mixed light frequencies that LEDs have, those lights need to burn much brighter to interact with your plants, and this creates an excessive amount of heat.

There’s a reason cannabis doesn’t grow in a desert climate: it’s just too dry and hot.

But that’s why we’re here… for some good marijuana growing tips and tricks with more emphasis on the lights and system you use.

If you go that route, you’ll need to have an adequate cooling system if you don’t want your plants to wither up and die before they even start budding.

LEDs work on efficiency rather than strength, so they aren’t generating all of that extra heat.

LED lights allow you to forego a complicated cooling system, and eliminate the need for additional equipment.

Another undeniable benefit of LEDs is the cost-effectiveness in both longevity and energy draw. Brighter lights require more power to run.

Think about how hot and bright an HID light is, for example. It takes a lot of juice to run one. Since LEDs focus on the quality of light rather than the quantity of light, they’re less dependent on your energy.

This goes hand in hand with generating heat. You won’t need to purchase and run a cooling system.

In terms of longevity, many LED lights can actually last for decades.

You won’t need to constantly replace them when they blow. In the event that you lose a diode or two with time, your light can still run efficiently.

But if you’d like to replace the blown diodes they’re a relatively simple fix, and the replacement parts are inexpensive.

Once you’ve decided to go LED, the benefits don’t stop.

There are strategies for boosting the efficiency of your LED lights even higher especially if you know some tips on growing marijuana indoors.

Aside from the benefits of simply owning one, some small tweaks can turn your LED optimized grow room into a supercharged powerhouse of massive yields.

Especially if you keep in mind these weed growing tips for beginners. I say that because these are the basics of the process.

10 Proven and Tested Marijuana Growing Tips

Cannabis buds up close in hands

1. Make Sure You’re Watering The Right Amount

Perhaps one of the most prominent cannabis growing tips and tricks is this one.

If you’ve ever worked with HID lights before, you understand how much water plants require beneath them.

This is because HID lights are mostly infrared, which greatly reduces the moisture content of your plants. Infrared is harsh, and it can dry out your leaves and harden your soil.

Since LED lights are only partially infrared balanced with other waves of light, the concentration isn’t enough to dehydrate your plants.

This means that watering LED-lit plants the same way you would water HID lit plants could potentially be drowning them.

Always check your moisture levels before you water.

Pay attention to growth cycles to make sure that your plants are getting the right amount of water to fulfill their growing needs, but always remember that LED-lit plants don’t need nearly as much water as plants grown under hotter lights.

Because of the little ambient heat intensity related to LEDs, your marijuana may frequently show a decreased need for water intake.

Always keep that in mind when watering, because newbie LED growers tend to overwater their marijuana which decreases root development and subsequent growth.

Marijuana plant roots require oxygenation to grow quickly.

Overwatering them decreases root oxygenation and reduces plant development and yields.

You don’t really need to water your marijuana as much when you are utilizing LEDs since the temp in your growing area won’t be really hot, meaning the evaporation of water in the pots will decrease.

With that, you might want to lower the irrigation and need to be delicate not to overwater your lovely plants particularly if you are switching from HIDs to LEDs and aren’t really used to watering less your plants.

And for additional knowledge,

Less watering also lowers the addition of nourishments.


Because with little heat and little water movements, marijuana utilizes its food relatively. That’s why you want to buy fewer nutrients just about 40% less.

In addition, it will reduce the risk of an unwanted build-up of nutrients in your medium and the harm of over-fertilizing is lessened, and that also means less cost!

2. Quality Soil = Quality Plants

Cannabis plant in soil

Well, this one is an obvious Tip, but I want to elaborate it for the sake of quality yields.

Humans and also other creatures need the right amount and quality nutrients to grow strong and thrive in this constantly changing world.

The same can be applied to marijuana especially if you decided to grow cannabis in soil instead of hydroponically.

Here’s a dedicated article on the differences between Hydroponics vs Soil.

To become robust and blooming, plants need to be in the right amount and kind of nutrients, on which they uptake from the soil by the use of their root system.

That is to say, if you placed your Marijuana plants in a cheap, poor-quality soil, then obviously it is most likely that they will start to become deficient in particular nutrition and minerals to sustain their effective growth.

To prevent malnutrition in your plants, they must receive the optimum yet sufficient nutrients from the soil of your choice, otherwise, they will have a pathetic growth.

You can try using high-quality organic soil that is complete of nutrients and has the necessary few amendments until near the end of the growth cycle.

3. Fertilizers and Boosters

Of course, utilizing quality soil must enable you to prevent adding particular supplements to it that might end up doing more harm than benefits.

If your soil is seemingly depleted of soil and minerals, your plants will certainly suffer from the consequences.

And this is where some growers chose to pick synthetic products to try to restore the health of their lovely plants.


The wrong use of these products might result in undesirable outcomes like a root burn and harming and weakening of leaves.

Due to this kind of instances, your plants’ health might result in nutrient lockout and may hinder sufficient photosynthesis.

That’s why it is always best to refer to some indoor organic cannabis growing tips out there.

4. Keep a Close Eye on Your Temperature

If you happen to be growing marijuana inside your house, then you must always remember that monitoring your grow room temperature is crucial for indoor marijuana growing tips and all.

Temperature control with HID lights is an absolute nightmare.

Heat fills the room, it has no place to go, and it’s doing undeniable damage to your cannabis if you aren’t regulating the temperature right.

LED lights are the opposite side of that coin. These hardly generate any heat, and in fact, many of them have cooling sinks and cooling fans to prevent them from creating excess heat.

While this sounds great, it does still leave some temperature concerns. With LEDs, you’re risking that your grow room will actually be too cool.

The best way to make sure you’re maintaining a temperature that’s warm enough is through the use of a dedicated thermostat.

It could be as simple as closing vents if your grow room is connected to a central air system, or placing a small, high-efficiency space heater on a low setting at a reasonable distance from your plants.

Marijuana plants sustain better results when their temp requirements are met.

During the flowering stage of the growth cycle, a daytime temperature of 64 degrees Fahrenheit (18 degrees Celsius) is fine. On the other hand, when it comes to night temperatures, plants are better off with 68 -75 degrees Fahrenheit (20-24 degrees Celsius).

Temperatures that are quite low might give detrimental effects on your marijuana plant’s health that might end up causing eradication.

With that said, it is always better to have an effective airflow and ventilation since it would play a crucial role when it comes to the overall quality of your marijuana buds.

It does not only help to maintain proper air quality, but it is also good to reduce the chance of mold, which like stagnant and humid environments with little airflow.

You can use fans to maintain a constant circulation of air.

Exhaust systems in conjunction with fans that pull the air out of the room can be employed to ventilate your grow room.

You must also remember that humidity is a prominent factor in growing your marijuana, and as a matter of fact it is often overlooked.

If you must know, humidity refers to the quantity of water vapor currently in the air.

Humidity can be manipulated in your grow room using certain humidifiers and dehumidifiers.

During the vegetative growth process, plants prefer a more humid environment and thrive in humidity. On the other hand, marijuana prefers less humidity during the flowering phase of their growth development.

You can lower the chances of mold when you lessen humidity during the flowering stage.

As LEDs will produce more heat than HIDs, there’s really no need for cool tubes.

The temp in your growing area can easily be manipulated, which comes convenient, particularly in the summer season when your marijuana runs the risk of excess heat. On the other hand, in colder seasons, where you may have depended on the heat produced by your HIDs, you may want to get an extra heater.

Though, LED grow light can save you a lot with your electrical bills, which must offset the budget of any heating.

Grow-area heat magnitudes are really different from LEDs since a 600 Watt HPS lamp wastes around 450 Watt of the electrical energy generating heat.

A fine quality LED light with a 400 Watt power draw would generate around 200 Watt of heat despite having the same result of a 600 Watt HPS.

That’s why the ideal LEDs only generate approximately half the heat of an HPS.

For some individual growers that will permit essential simplification of the grow area, for instance, no air conditioning in hot temperatures.

On the other hand, some growers can turn down air extraction frequency or use smaller extraction fans. Conventionally, many marijuana growers fight grow area temperatures, their grow areas typically run around 3 or 4 degrees Celsius above the maximum point.

With LEDs grow areas that run naturally at a cooler maximum temp.

Why waste electrical cost to make residual heat from HPS just to have to pay a second time to eradicate the heat, overall, LED is a better choice.

5. Adjust Their Distance From Your Plants

Plants growing under lights indoors

This plays in really much with the first subject; less heat permits you to get your LED grow lights much closer to your marijuana canopy.

This ensures the increase in your light magnitude permitting you to maximize what you get out of your grow lights.

But remember that LEDs have to be in a balance between light magnitude and your coverage area.

You can get an idea with the grow lights manufacturer’s instructions and take measures from there.

Every light is designed to cover a different amount of square footage, and cannabis plants need different amounts of light at different stages of their growth.

While you’re germinating, you’ll probably want to hang your lights closer to your plants, depending on your specific LED light’s canopy penetration abilities.

They need more focused light while they’re very young.

As your plants grow, they’ll start to reach your light.

You need to constantly adjust the height of your lights to accommodate the growth of your plants. If the lights are too low, they’ll be stifling the growth of your plants.

Making these adjustments is crucial.

Just pay attention to how your plants are growing and try to maintain a reasonable distance between the top of your plants and the bottom of your lights.

Another important reason for the adjustment and proper placement is that you’ll have multiple plants primarily assigned to the same light.

If the light is most focused on the central plant that plant is going to eat up everything the light has to offer while the neighboring plants suffer.

LEDs’ power degree level has been increasing essentially over the previous years, and at the same moment, so have the LEDs’ effectiveness.

Recent LEDs would convert 20% of electrical energy into light. But now, the latest LEDs convert over 60% of electrical energy into light and that figure is increasing.

When light magnitude is too great, the tips of your marijuana plants will bleach.

Ultimately, it is a sign to raise the LEDs higher or to tie down the highest branches of your marijuana.

Distance equates to adequate distribution, so all of your plants can use the light equally.

Nowadays, LEDs are very strong and hanging distance will certainly play a significant role in the LED’s performance.

The most usual mistake we tend to do is when LEDs are utilized a little bit too near to their respective plants, particularly seedlings that could suffer stress if the light is too great for the first couple of days.

A very simple solution is to maintain seedlings in the tent edge that might have lower magnitude light unlike to the center of the tent, or just to lift the light and permit the plant to grow into the additional light while it stretches after.

6. Remember These Minerals: Calcium and Magnesium

LEDs typically generate less heat than HPS grow lights of similar productivity.

The lower heat degree from LEDs means the leaves of a marijuana plant basically evaporate less under LEDs compared to HPS.

The transpiration variations mean that Calcium and Magnesium elements can be less mobile under LEDs and this might result in deficiencies that you will need to correct with nourishment supplements.

At some point, you might not recognize this problem because the soil and various grow nutrients already possess enough levels of calcium and magnesium.

Don’t forget that Calcium and magnesium supplements are vastly available in your favorite grow shops.

7. Use More Lights

Just like you don’t want to deprive all plants under the same light, you don’t want to assign too many plants to a single light.

Placing one light every few feet will create pockets of overlap, so plants at a certain distance from the light won’t be left in patches of inadequate lighting.

Measure the grow space accurately, determine its square footage, figure out the square foot coverage of your preferred LED light.

You need, at the minimum, enough lights to cover the entire square footage, especially if you’re growing a lot of cannabis.

Buying a few extra lights to fill in gaps will make sure the plants at the outer edges of the LED coverage won’t suffer.

For supplementary lights, you can select smaller LEDs that cover less square footage to prevent too much light from saturating your plants.

Plants require enough light for it to make energy, an energy that will permit them to thrive and produce the greatest yield possible.

It’s like this…

When light strikes the area of leaves, chlorophyll plays a significant role in converting this energy into a certain type of sugars.

And then these sugars will be the food of plants, and the more they make and consume, the larger and more blooming they will become.

This is the reason why plants must be given as much light as possible during the growth process.

You must also remember that you need to realize that not all light sources are of equal quality.

If you believe that you can get through by utilizing a standard desk lamp, then good luck to you, your plants will soon be dead.

That is to say when growing indoors, strong and mighty grow lights such as HPS and LEDs are fundamental to sustain your crop with sufficient light to develop fast and strong growth.

Powerful, bright lights will certainly do wonders for your plants and will result in improved survivability and greater yields.

8. Turn Your Cycles Into Science

If your plants are receiving natural light of any sort, like from windows in your grow room, invest in some blackout curtains.

Light interference can prevent your LEDs from doing their job properly. When you’re working in a closed system, it’s easier to control all of the light factors that affect your plants.

Some lights will have switches for different phases of plant growth, and you need to know when to flip them.

Familiarize yourself with the growth cycle of cannabis to learn what it needs during certain stages of its life.

In general:

  • Germinating plants do well with 24 hours of light.
  • Vegetating plants require approximately 18 hours of light.
  • Flowering plants need about 12 hours.
  • When you’re trying to produce a healthy cannabis crop, you can safely extend the light time up to 18 hours.

Consistency is important, and if they aren’t getting the recommended amount of light and darkness, you can drastically disturb their growth pattern.

Try putting your lights on a timer. Chances are, you aren’t near your grow room often enough to switch the lights off and on like clockwork.

Allowing a timer to do that for you will provide your plants with the consistency they need.

You’ll only need to adjust the timer as the growth stages change, so you can basically set it and forget it for a little while.

Your life will be easier, and your plants will be receiving optimum care.

9. Experiment With Different Combinations

Not all cannabis is equal, particularly when it comes to the flowering stage.

If you’re looking to arrive at harvest time a little faster, try tampering with the amount of infrared light they receive.

Many lights come with dials that specifically adjust certain amounts of light, and providing flowering plants with predominantly infrared light will generally help robust buds pop up a little faster.

If you learn to understand the relationship between your cannabis and your LED lights, you can determine exactly what the wavelengths are doing to them.

Experimenting with different amounts of different lights can affect the speed and quality of the buds you’re producing.

If you’re willing to get adventurous, you can concoct your own maximum efficiency lighting scheme.

Of course, other growers will brag about their results online, so you can take a peek at what they’re doing and attempt to duplicate it.

Unlike HIDs, LED grow lights can be maximized to output more of a particular light spectrum.

This is perfect because marijuana needs more of a certain type of light at various times throughout the growth stage.

With the latest LED technology, everyone can possess the blue and white LED grow lights for the vegetative phase and different red lights for the flowering stage.

These particular kinds of spectrums are usually switchable to match any stages of the plant’s growth development.

A lot of the latest LED grow lights also include infrared and Ultra Violet rays to further penetrate your marijuana to generate as many buds as they can.

10. What’s with Taste and Aroma?

Expert LED growers have discovered that the lower intensity of grow area heat and the chiller tent conditions with LEDs is permitting more of the fragile terpenes and flavonoids to keep in the plant’s cells instead of being lost to the air in a hot HPS tent.

Someone that has opened a grow cabinet with mature marijuana plants under HPS grow lights which have been operating at high temp, that is about 104 degrees Fahrenheit (40 degrees Celsius) might have smelled the excellent aromas that are oozing out of the plant.

Operating your grow area cooler using LEDs permits you to keep more flavor on your marijuana rather than losing them to the atmosphere.

Final Conclusion

Differentiate chunky HPS grow lights with a parabolic reflector to a little refined LED.

The HPS is hot and quite heavy.

An LED grow light runs cooler and is usually small and slim that won’t take up that much space in your grow area. Growers with small grow rooms frequently find LEDs as the best and sometimes only option to produce quality marijuana.

With that said,

The benefits and various advantages of LED grow lights are becoming more obvious and this can be seen in their increased famousness.

With each passing months and years, the effectiveness of LED constantly improves.

They are cheaper to operate compared to HPS and obviously run much delicately.

The combined advantages of LEDs mean that HPS is clearly looking like a bit outdated invention, generating a light spectrum that is not maximized for marijuana plants, on the other hand, LEDs don’t really waste that much energy generating the worthless orange/green/yellow spectrums.

LEDs only utilize energy-generating wavelength-particular worthy light at high effectiveness with little wasted energy.

It is a great technology that you will see more of in the near future.

We hope these tips have helped you grow your very own cannabis!
