How Big Should Buds be at 5 Weeks

By now, your Cannabis plants should be about 5 weeks old and have started to form buds. The buds will continue to grow in size and density as the plant matures, but you’ll want to ensure they’re the right size before you start harvesting.

So, what is the right size for buds at 5 weeks? That depends on a few factors, including the strain of Cannabis you’re growing and the growing environment.

But generally, buds should be around the size of a golf ball or a little bigger. Too small, and they won’t have much THC or other cannabinoids; too big, and they might not cure properly.

In this article, we’ll take a closer look at what to look for when harvesting Cannabis buds at 5 weeks old.

Understanding the Flowering Cycle of Marijuana Plants

Marijuana plants grow through a process of vegetative and flowering stages. The vegetative stage is when the plant grows leaves and extends its stem. The flowering stage is when the plant starts to produce buds.

Buds will continue to grow and swell in size as the flowering stage progresses. Around week 5, they should be roughly the size of a nickel or a quarter. As the buds get bigger, they will also start to fill with resin, the THC-rich oil that gets you high.

It’s important to remember that not all plants will reach this size by week 5. Some may take longer, and some may reach this size sooner. But this is a good general guideline to follow as you keep an eye on your plants’ development.

The Different Stages of the Flowering Phase

Your buds will go through different stages as they grow; at 5 weeks, they should be around the size of a nickel. You’ll see the first signs of pistils, the tiny white hairs that grow around the bud.

The pistils’ color will also change from white to orange to red. This is a good indicator that your buds are getting close to maturity. As the pistils change color, the THC levels in the bud will start to increase.

Timing It Right: When Buds Usually Start Forming

At around the five-week mark, you should start seeing your buds begin to form. As we mentioned before, each strain of cannabis will have a different timing for when its buds begin to form. Some strains, like OG Kush, can take up to eight weeks for the buds to fully develop.

Most importantly, you can expect the buds to reach their desired size between the fifth and seventh week. Of course, this will vary depending on the type of plant you’re growing, the climate, and other factors. But as a general rule, that’s when you can expect your buds to be at their biggest.

What to Expect at 5 Weeks — When Buds Should Be Reaching Optimal Size

You should expect to see the buds reaching optimal size at five weeks. This means they should be 4-8 inches long and at least 0.5 inches thick. If they aren’t, don’t panic—it could just be that there is still more growing.

At this stage, you will also notice that the fan leaves have begun to turn yellow and die off, allowing the buds to receive more light and air. The buds themselves are quite dense now, as well as sticky with resin. At times, you might even smell a sweet scent emanating from them!

If your buds are not reaching optimal size at this point, try increasing the amount of nutrients and water you feed them with. Also, consider investing in a few higher-grade grow lights if you don’t already have them. These can make all the difference in helping your plants reach their maximum growth potential.


Tips for Maximizing Your Bud Size and Quality

The buds will grow rapidly at this stage, and you want to ensure they get enough nutrients and light to reach their full potential. Here are a few tips that will help you maximize your bud size and quality:

– Make sure the plant is well-fed and getting enough nutrients. Check the feeding schedule for your particular strain of marijuana, as some plants require more or less fertilizer than others.

– Avoid stressing the plants out with too much or too little light. You want to slowly increase the light intensity as your plants continue to grow so that they have enough of it to create big, dense flowers.

– Prune regularly to ensure that all parts of the plant get access to light and airflow. This will help you get bigger buds since there won’t be any competition for sunlight.

– Finally, it’s important to remember that different strains have different timing when it comes to flower production, so read up on them before you start growing if you want bigger buds faster.

Potential Reasons for Stalled Bud Development

At 5 weeks, you should see some decent-sized buds with consistent growth. But if things suddenly seem to have stalled, there are a few potential reasons why.

For starters, the plants may not get enough nutrients—especially phosphorus and potassium—to help develop their buds. If your soil isn’t up to snuff, you may need to supplement with a balanced feed like Miracle Grow or other liquid fertilizers.

You also want to ensure your lights are positioned correctly so that all parts of the plant get proper lighting. If your lights are too far away or only hitting one side of the plant, that could explain why your buds aren’t growing as expected.

Finally, your environment may be too hot or too cold for optimal growth, which can also cause buds to stop developing at 5 weeks. Make sure you’re keeping track of your grow space’s temperature and humidity levels and adjusting as needed, so everything is right.


So at 5 weeks, your buds should be about the size of a pencil eraser. Again, this is just a guideline and will vary depending on your growing strain. But if you keep an eye on your buds and ensure they follow this general size guide, you will be able to harvest the perfect amount of buds every time.
