Learn how to grow a marijuana plant from start to finish… 5 Secrets to Growing Top-Shelf Bud Have you ever had cannabis that was just…so so? Mediocre? Just okay? Cannabis that’s ‘just alright’? Have you ever had cannabis that was so good, you want to Are These Cannabis Seeds Good? Growing with bad marijuana seeds is particularly harsh on growers of all levels. This is mostly because it’s tough to pinpoint when the seed itself is the actual
How To Grow High Quality Plants
Are you in one of the many states that has legalized cannabis? If yes, then you may have found yourself with a new crop to plant in the garden this summer. Growing a new crop can be challenging even for veteran gardeners, but with a little help from your friends at Impello you can avoid some of the common mistakes that lead to a poor crop.
Pick Reliable Cannabis Seed Banks
When purchasing cannabis seeds, you might often choose the cheapest ones to save some bucks. However, the quality may be compromised, and you’ll end up spending more than you have to. That’s why you should pick cannabis seeds with the best genetics. Conduct your research so that you can buy from trusted cannabis seed banks. Cloning can be a good start too — just make sure to get the clones from reputable sources.
Provide Enough Lighting
One essential element for growing cannabis is proper lighting. It’s not only the quality that will be affected but also the speed and size. While marijuana grown outdoors gets natural light, indoor cannabis needs extra care. This means that your usual lightbulbs are not enough to make up for the absence of lights.
Invest in more premium lights, hoods, and reflectors. Get high-intensity (HID) lights, like high-pressure sodium (HPS) or T5 fluorescent lights. You can also use LEDs to save on energy costs. Just make sure to choose full-spectrum LED lights that allow you to modify the wavelength based on the marijuana plant’s needs as it grows.
Enhance Water Quality
Dissolved solids from water can cause adverse effects on your marijuana plant. For instance, domestic water contains chlorine and fluoride. While they will not kill the plant, maximum yield can’t be expected. So, consider using a reverse osmosis system or filtration. Make sure to change the filters regularly. It’s also best to test the water from time to time to check whether the parts per million (PPM) of dissolved solids remain the same.
Secure Enough Spacing and Ventilation
Wondering how to grow high-quality marijuana? Allow enough spacing between the cannabis buds. Make sure no leaves or branches block the airflow. You can apply low stress training (LST) where you tie the plants down while they’re still young to ensure that the light is well-dispersed, improving the plant’s overall health. Using other tools like filters and fans will also help you maintain the airflow.
Provide Sufficient Amount of Nutrients
One of the 10 steps to growing weed is providing just the right amount of nutrients per growth stage.
Tribus Original is the perfect seedling to harvest cannabis growing products on the market today and it’s very versatile. Usage rates are 1 ml per gallon and with a price tag under $60 for a 250 ml bottle, and a little goes a long way. Because it consists of beneficial bacteria you really can’t overfeed your cannabis plants with it, and it creates stronger plants from the inside out. For best results apply it to your grow media at least once a week. Tribus is compatible with all grow media, including hydroponics and even field application.
In addition to Tribus, these nutrients are necessary when feeding cannabis plants.
Nitrogen, potassium, and phosphorus may be the three main nutrients that your cannabis plants need. However, they also need other nutrients like:
During the flowering stage, various supplements can be beneficial too. These include:
Prune Cannabis Properly
While low stress training does not involve cutting, you have to perform pruning to promote yield increase in plants. It also helps you get rid of buds that are not in their best condition. This way, buds become fewer but larger and healthier. Consider removing the lowest branches to ward off pests. To ensure that the plants recover and grow faster, prune during the vegetation stage.
Keep the Right Room Temperature and Humidity
Cannabis can grow well under several conditions, but you need to ensure that the room’s temperature and humidity satisfy the weed’s needs. Even small changes can affect its growth, so focus on the temperature and humidity in each stage.
For seedlings and clones, the preferred humidity levels range from 65% to 80%. This way, they can take up enough water and have stronger roots. In terms of temperature, keep it at 25 degrees Celsius or 77 degrees Fahrenheit during the day and 21 degrees Celsius or 70 degrees Fahrenheit during the night.
In the vegetative stage, moderate humidity levels are necessary. Every week, you can decrease it by 5%. Around 40% to 70% will work. Given that the roots are stronger during this period, they can absorb more water, so lowered humidity levels are preferred. For the temperature, you can raise it a bit — around 71 to 82 degrees Fahrenheit during the day and around 64 degrees Fahrenheit to 75 degrees Fahrenheit at night.
Reducing the humidity levels to 40% to 50% is needed during the flowering stage. You can make it 55% but never 60%. Also, the temperature can decrease to 68 to 78 degrees Fahrenheit. Then, in the latter part of the flowering period or one to two weeks prior to harvest, reduce humidity levels from 30% to 40%.
Meanwhile, the temperature can fall between 64 to 75 degrees Fahrenheit or 18 to 24 degrees Celsius with lights on and 16 to 20 degrees Celsius for several nights before harvest. To monitor the humidity and temperature, use a hygrometer and thermometer.
If you aim to lower the temperature, you can do the following:
- During the day, keep the lights off; during the night, on.
- Add an air conditioning unit. This can also help reduce humidity.
- Use a cool tube if you are growing marijuana with HPS lights.
To raise the temperature, you can:
- Utilize a quality space heater with a thermostat.
- Use grow lights with higher watts.
- At the bottom of your grow room or tent, place a heating mat.
If you want to drop the humidity levels, perform these steps:
- Water your marijuana plants immediately after switching on the lights. Given the quick absorption, humidity levels will decrease.
- Get a humidifier.
- Have an airflow fan upgrade to increase the supply of cool air.
Enhancing humidity levels can be possible through the following:
- Use a humidifier that has enough water reservoir to avoid frequent refills.
- Using a spray bottle, mist your marijuana plants. However, this shouldn’t be done to flowering plants as it can result in bud rot.
- Bring larger plants inside the room. Compared to seedlings, they perspire more, raising the humidity levels in the grow room.
- Consider hanging wet towels inside your grow room.
Maintain Enough CO2
Did you know that providing your marijuana plants with sufficient carbon dioxide (CO2) helps improve their growth by 20%? CO2 is crucial in photosynthesis, where cannabis absorbs light and turns it into energy. Excessive CO2 or a lack of it can be detrimental to your cannabis plants. So, you should know how to provide them with the right CO2 levels. Ideally, it should be above 250 PPM.
To supplement your plants with extra CO2, you can use the following:
- CO2 generator: To produce carbon dioxide, the CO2 generator burns natural gas or propane. It automatically turns on or off if a certain CO2 level is reached. However, burning the gasses can create heat. So, it’s advisable to use one in a larger grow room.
- Compressed CO2: With this option, the manufacturer produces the gas and compresses it into a tank. No heat is produced once gasses are released, so you won’t have issues with the temperature and humidity levels. It can also be set to automatic using a controller. Note, however, that both CO2 generators and compressed CO2 can be relatively costly.
Know When To Harvest the Cannabis Plants
Harvest time keeps growers excited, especially given all the efforts exerted to produce healthy and quality buds. However, cutting them too soon will defeat the purpose and waste all your hard work as the tetrahydrocannabinol (THC) content will be low. So, harvest them at the right time based on the following indications:
Dry and Cure Cannabis Properly
You may think you’re done once you harvest your cannabis. However, drying and curing are important steps to producing quality and tasty buds. First, drying helps reduce the bud’s moisture content to 15%. It also enables you to maintain its taste and the natural compounds in it, including THC. To dry cannabis properly, follow these steps:
- Cut down your cannabis plants. While most growers prefer to cut off the branches, some want to cut until the base and hang them upside down. Others will also cut off each bud and then place them on a drying rack.
- Trim to remove larger fan leaves. Doing so will contribute to your buds’ improved look. If you’re residing in a place with less than 30% humidity levels, trim fewer leaves.
- Begin the slow drying process. A temperature of 65 to 75 degrees Fahrenheit and 50% humidity is preferred. If it exceeds 80 degrees, the terpene content will go away. While hanging the buds upside down is the most common method, you can use a drying rack or cardboard to lay them out. Generally, you need three to seven days to dry the buds well.
After the drying process, you can now proceed to curing to preserve the plant’s cannabinoids or compounds and terpenes. Simply perform the following:
- Put the cannabis buds into mason jars with a wide opening. Other alternatives include plastic or wooden vessels.
- Secure the container in a dark and dry area. Humidity levels should range from 60% to 65%.
- Check the containers regularly. Open them at least once a day for two weeks. Doing so will remove extra moisture and accommodate fresh air.
While your cannabis should be ready for use in two to three weeks, keeping it for around two months is recommended for maximum results. Commercial grow operations may prefer to use chemicals to hasten production. However, the whole experience of users may be compromised.
There are multiple factors to consider when growing cannabis on your own. However, growing cannabis indoors step by step with our guide above will help you produce quality buds that you’re proud of.
5 Secrets to Growing Top-Shelf Bud
Have you ever had cannabis that was just…so so? Mediocre? Just okay? Cannabis that’s ‘just alright’?
Have you ever had cannabis that was so good, you want to save it so you can have it as long as possible? Cannabis so good that you inspect it closely as if you could somehow see why it’s so great?
What makes the difference between the two?
The look of the bud in addition to its potency, taste and smell is what makes cannabis seem top-shelf to the user.
But what happens when you’re growing cannabis that makes gives it these desirable qualities?
In this weeks issue of the GrowWeedEasy newsletter, you’re going to see what growing practices are responsible for making the difference between mid-to-low-grade cannabis flowers and top-shelf bud!
You’ve probably heard it a million times, but good cannabis starts with good genes. Having seeds with good attributes to work with gives you a plant that will flourish under the right conditions as opposed to just surviving.
All cannabis strains have their own attributes, so the best thing to do is to find one that fits what you’re looking for. Some strains are high in THC, some are known for tasting pleasant, some are high in CBD, etc.
In any case, growing cannabis from ‘bagseed’ is an easy way to lower your chances of growing great weed. In a best case scenario with bagseed, you’ll get a female seed as good as one from a seed bank. In a not-even-the-worst-case-scenario, you could get a male seed that grows a runt plant from a weak strain. Or even worse…it’s not even cannabis!
There are quite a few places you can go to get seeds with good genes, I’ve had the most luck and the least trouble with ordering from a trustworthy seed bank. Personally, I use Nirvana Seeds for their high-quality strains and I’ve got 100% of my shipments from them, but I’m also a big fan of seeds from Barneys Farm and DNA Genetics.
High Light Intensity
The amount of light your plant receives in it’s life can be used as a good indicator of how close it will get to its maximum potency when all other conditions are met. In fact, outside of genetics, light-intensity plays the biggest role in determining how big/hefty/potent your buds will be.
This means that even if you get seeds from a strain that is known to have 22% THC, the plant will need enough light to allow it to grow to this level of potency. This doesn’t mean that you need a 1000 watt HPS to grow great bud, but it does mean that you’re probably not going to grow top-shelf buds with a single 26 watt cfl bulb.
So much is enough?
Unfortunately, this is a question that is very difficult to answer as it depends on the specific strain you’re growing, the area you’re growing in, and the size of the plant being grown (smaller plants need less light). The general rule to go with is “more is better”, and watch your plants to see how they react. In most cases, it’s hard to give your plants too much light unless you have a high powered LED or a 1000 watt HPS.
Harvesting At The Right Time
For many growers, this is the toughest part to get right. Why?
Because you can buy seeds with awesome genes, and you can buy a MH/HPS combo that will flood your cannabis with light, but you can’t buy patience! And boy will a flowering cannabis plant try your patience!
Aside from becoming ever more picky about which nutrients they get, flowering plants will begin to smell ever-more enticing and look more and more ready to harvest. The problem is that there is a small 2-3 week window in which cannabis should be harvested, and most growers (myself included) get the urge to take them down prematurely.
Whenever your plants are flowering and you get the feeling you should harvest them because they look ready, reference this page and double check to make sure they are: https://www.growweedeasy.com/how-do-i-know-when-to-harvest-marijuana. Harvesting early is an easy way to ruin the buds you’ve taken so long to grow, so double, triple and quadruple check they’re they’re ready before you cut down a single bud!
Many growers consider drying and curing to be two parts of the same process, but I like to separate them to really underline the important steps involved.
It’s important to not only dry your newly harvested buds before they can be used, but you want to dry them as slowly as possible. Drying buds too quickly can make them crispy and harsh, and will make them smell – ironically – like cut grass.
A good way to keep moisture in the plant and keep it from drying too quickly is to trim the harvested branches after they’ve been dried. Having the extra leaves left on will cause the plant to dry slower since there is more actual plant to dry out.
Personally, I trim my buds before I dry them since it seems to be easier for me while trimming and when I’m cutting buds off of the stem. From there the buds can be hung up to dry, or placed on a drying rack.
In either case, I would recommend leaving on as much stem as you can as it slows the drying process, and is easy to remove later. I would also recommend hanging your buds upside down to dry before testing any other methods. Anecdotally, I’ve found that buds that retain their stems and are hung upside down to dry tend to dry much slower than on a rack…which is exactly what you want!
In short, dry your buds for as long as you can. Aim for more than 5 days, with a goal of 8-10!
Once your buds have been properly dried, the only thing left to do is cure your buds. This last step won’t add to their potency per se, but it’s largely responsible for the taste and smell we all love.
Essentially, curing your buds involves sealing them in an airtight container for at least 2-3 weeks. During this time, the jars are periodically jostled, opened, emptied and refilled with the same buds. This will give the buds to ‘get rid of’ certain not-so-tasty chemicals, and the jostling, emptying, etc. will help prevent mold from forming.

The Short Version
Here’s the meat & potatoes of this article in case you forgot any part of it(as some of us are prone to do):
Potent, top-shelf bud requires these 5 things:
- Good genes (Get good seeds)
- High Light Intensity (More light is better for your plants)
- Harvesting at the right time (You only get one chance; patience is key!)
- Slow Drying (The slower you dry your bud, the better)
- Proper Curing (Put them in a jar and let them out every so often until they’re done)
Great Bud Starts with Great Seeds!
What’s the first step in creating fat, potent, mind-blowing buds?
Make sure you start on the right path by beginning your next grow with a with a hearty, potent, higih yielding strain!
“Nirvana Aurora Indica is an F1 hybrid of Afghan and Northern Light. Its plants stay short, producing heavy colas and dense buds. This marijuana strain produces exceptional amounts of resin, resulting in a deep, near-black hash with a tasty aroma and a heavy buzz.”
“BlackJack produces hard buds with huge, grape-like calyxes that are completely encrusted with THC! The smoke is heavy and flavorsome, and produces an exceptionally long-lasting high.”
“Nirvana Wonder Woman is another one of those fabulous new high-volume marijuana plants. Wonder Woman bears rock hard buds which are easy to trim. The smoke of this cannabis variety has a classic, rich, skunky flavour accompanied by a long-lasting buzz.”
Are These Cannabis Seeds Good?
Growing with bad marijuana seeds is particularly harsh on growers of all levels.
This is mostly because it’s tough to pinpoint when the seed itself is the actual problem. Most growers will blame themselves for a problem that shows up in their grow long before they assume it’s the seeds.
The term ‘bad seeds’ usually refers to any type of seed that has a significantly higher likelihood of causing problems in a grow. I’ll cover the most common reasons for bad seeds in this tutorial!
These cannabis seeds were germinated between two wet pieces of paper towel!
These are pot seeds you might get from a friend, or maybe you have them stashed somewhere and forgot how you got them. In either case, if the shell of the seed looks beat-up, it may not germinate as well or quickly as seeds that were stored in good conditions.
Seeds are a little nugget of genetic material than can hopefully grow into a plant. And like all other genetic material, it doesn’t last forever! Although seeds can be viable for quite years and years after they’re first produced, the chances of them successfully germinating goes down over time (and old seeds also tend to take a lot longer to germinate than fresh ones). The resulting seedlings are also more likely to be slow growing. But sometimes they sprout like they were born yesterday!
Check out the picture below. We sprouted all the plants at the same time. The tub on the right has seeds that were planted within a week of receiving them in the mail. The tub on the left has a very popular strain with award-winning genetics… but the seeds were more than 6 years old from when we first bought them. Even though they were all put into the tank at the same time and the new seeds grew like crazy, the seeds on the left got outpaced by algae – only one sprouted and though its roots keep growing and growing the actual never got any bigger than two round leaves even after a month!
Pale or Flimsy Seeds
When I first started growing I was told that good cannabis seeds needed to be very hard with dark tiger striping. If you could crush it between your fingers, it was a bad seed, or so I was told. This has not been my experience at all!
Did you know that the “stripes” on cannabis seeds are actually part of a protective coating? The “pale” seeds in this photo are actually just regular seeds with the coating rubbed off!
Over the years, some of my very best plants came from flimsy, light brown seeds that very likely would have been easy to crush between my fingers.
So I’m a big believer in the fact that if you put the seed in the ground and a fast-growing healthy seedling comes out of it, it was a viable seed! Don’t toss a seed you are really interested in just because it’s a little pale; give it a chance (I’m talking more about tan seeds, it’s very unlikely a yellow seed will sprout)!
Note: Although the hardiness of the seed was likely important in the wild, cannabis growers have been breeding plants for generations to make good buds, not seeds! We growers strive to provide an ideal germination environment that lets almost any seed germinate successfully. As a result, we haven’t been breeding for seed hardness. Just like a teacup poodle hasn’t been bred to be strong, cannabis seeds haven’t been bred to be strong. They have other qualities we love
Bag seeds you randomly find in your buds aren’t supposed to be there, so that means that the genetics are a toss-up. Even if the seeds started with good parents, there’s no telling how high or low the quality will be. Unfortunately, the only way to find out is to grow it… Some growers win the genetic lottery, but many others lose out.
If you talk to breeders, you’ll learn that when you breed two “star” strains together you don’t always get what you’d expect. It seems like every one of the seedlings (or at least most of them) should be capture the best qualities of both their parents.
However, that’s not how genetics works most of the time. Without intensive breeding and backcrossing, when you mix two random plants you often end up with only a fraction of the seedlings capturing the best of both parents.
Bag seeds are a wildcard! You never know what you’ll end up with!
So depending on how the seed was originally made, bagseed often has a lot of variety. Even if the buds you got were an incredible quality, it doesn’t necessarily mean that the seeds will produce buds like that. If you’ve ever gotten involved with breeding or growing other types of specialized plants like roses, hops or even apples, you’ll know that seeds rarely breed “true” to the parents, and cannabis isn’t any different.
That being said, sometimes bagseed is all you have, and lots of growers get lucky!
Hermaphrodite or Male Plants
If a cannabis seed was produced with a male doing the pollinating, it means that about half of the resulting seeds will end up being male (which you don’t want, because only female flowers turn into bud). In that case, you want to determine the gender of your young plants as soon as you can so you can toss all the male ones before they start making pollen sacs.
If growing with seeds that were produced without a male plant around, the seeds sometimes end up being hermaphrodites, which means they grow both male pollen sacs and female flowers (again, something you don’t want).
One of the best ways to ensure all your plants end up being female is to start with feminized cannabis seeds from a trustworthy breeder.
Sometimes It’s Random!
Even if you’re starting with the best, most fresh seed stock, occasionally you’ll get an individual seed or plant that just doesn’t grow as well or quickly as the others, or maybe you’ll get a super awesome seedlings that just starts kicking butts and taking names from its first moment.
Natural variation is totally normal! It’s always a good idea to sprout at least a few more seeds than you need in case you happen to run into a runt, or some other expected problem! If all your plants are healthy and growing fast except one, you can blame the seed!
