Some of the most knowledgable cannabis growers in the world aren’t growing on a professional level. Instead, they’re growing for personal medical reasons from home in Canada with an ACMPR license to grow. Although many ACMPR medical growers are dealing with small grow operations, a lot of them know exactly how to cultivate the perfect crop.


What do we mean by perfect crop? A few things, actually. First off, a perfect cannabis crop will be healthy and free from deficiencies resulting from common mistakes like a lack of nutrients or a less-than-ideal grow environment. But what’s more important to most growers when it comes to the perfect crop is harvesting beefy, potent, flavorful buds.


Whether it be a small-time ACMPR grow op or a massive commercial cannabis operation, high yields of high-quality cannabis are the main features of the “perfect” crop. But the real question on every grower’s mind is, how can I make this possible?


There’s a lot of information on the internet that focuses on answering this question, but there’s also a lot of under-the-radar info that growers tend to keep to themselves. These secrets to mastering your next cannabis crop might just help you to cultivate the high-quality buds you’ve always hoped for.

It All Starts With Quality Seeds

This might seem like a no-brainer to you, but a lot of new growers underestimate the power of quality seeds. They focus only on choosing feminized seeds of funky strains, and often they fail to take seed quality into consideration.

According to sites like Cannabis Growing Canada, many ACMPR growers are receiving licenses for as many as 500 plants. And you know what the main focus of the best of these growers is? Finding a seed bank with a great reputation and not being stingy on cheap seeds or clones.

The only way to consistently produce killer buds time and time again is to consistently use quality seeds for each crop. The best way to do this is to shop at a reliable seed bank that is invested in maintaining the purity of each strain’s genetics and lineage.

Choosing Strains Is Situational and Subjective

The next “secret” that all the best ACMPR growers are aware of has to do with the importance of strain selection. Selecting a strain should never be based on which strains are “cool” at the time or which ones have outrageously high THC levels. There’s so much more to think about when deciding on the ideal strains for your next crop.

Of course, you should be thinking about the high effects or medical benefits you’re hoping for, but you also need to think about your level of expertise and the specifics of your grow room. Every strain grows in its own unique way, and some are more difficult to handle than others (and some take up more space than others).

Cut Clones from Only the Best Mother Plants

Similar to the rule about using only the best seeds, you might think this next one is obvious. But even so, it’s important to iterate the importance of quality, especially when it comes to choosing mother plants. Starting from clones cut from a quality plant is a much more reliable practice than using seeds for your ACMPR grow, so clones should be your go-to choice over seeds.

However, cutting clones from an unhealthy or inadequate mother plant won’t get you very far. Once you’ve started growing, you should be making an active effort to identify the best plant in the crop. The one that stands above the rest should be moved to a vegetative state once the time is right – this is your mother plant.

Focus on Humidity More Than You Think You Need To

So you probably already know that humidity is an important aspect in creating the ideal environment for your plants. But the thing you might not realize is that humidity is more than just a key player in determining how well your crop turns out.

The main thing to remember about humidity is that it’s not a fixed range throughout the entire operation. Plants thrive in different humidity conditions with every phase, and humidity needs to be altered from germination to vegetative to flowering – even early and late flowering has different ideal humidity ranges.

Humidity needs to be higher during veg, seedling, and cloning than it does later on in the operation. During the last 2 or 3 weeks of flower (right before your plants are ready to be harvested) humidity levels should be at their lowest.

Before Harvesting, Don’t Overdo It on the Watering

So you already know that humidity should be set at a lower range a few weeks before it’s time to harvest. The same goes for watering your plants. In order to ramp up resin production near the end of the flowering phase, you’ll want to gradually decrease the amount of water you give your plants with each feeding.

By reducing the volume of water you give your plants near the end of the flowering phase, you’ll be able to stimulate them to produce more resin since they’ll be attempting to protect their precious buds. More resin also means more THC and a more potent crop in the long run.

It’s OK to Stress Your Plants (But Only a Little Bit)

One thing most ACMPR growers will agree on is that stressing out the crop is something that should be avoided at all costs. But in a way, this isn’t entirely true. A lot of cannabis cultivation research is showing that the ultimate way to boost terpene production is to gently cause stress, the keyword here being gently.

One technique that more advanced growers use is LST, which is short for Low Stress Training. There are more aggressive techniques as well for boosting terpene production, but new growers should start with LST.
