Full Discussion on Flowering At Different Plant Length Yields!

You’ve seen 6” to gigantic 24” flowering cannabis plants from different growers. And not everyone has the huge space to let the plants grow tall vertically. But then you can’t also rush mother nature to flowering your plants when they’re small.

So, is it possible to flowering at different plant length yield?

For 6” length plants, the yield is about 1 oz. For 12” plants, you can expect 3 oz. yield. As for your 18” plants, expect a max. 6 oz yield. Finally for 24” plants, the yield is around 45 oz. However, flowering has less to do with height and more to do with age. It takes about 5-8 weeks for a cannabis plant to reach the flowering stage.

Now, let’s go through all three different lengths and their maximum yields.

Flowering At Different Plant Length Yield 

Here’s a quick chart to know the different levels of yields from different plant lengths-

Flowering at 6 Inches Yield

Flowering a cannabis plant when it’s only 6” in height is hardly possible. However, it’s doable only if you’re growing it with the ScrOG method.

After reaching a 6” height, tie your plant down and clip the tops. Then the nutrition and growth will spread horizontally. Follow the 12/12 lighting method. After harvest and drying, you can expect about 3 oz. Yield. And that’s the dry weight. 

Nutrients:

Maintain a 50% peat, Silica, dolomite lime, gypsum, and 50% Vermiculite. Manage the pH of the plant to 5.5. 

Provide K, Mg, N, and P to the soil. To save yourself from the hassle, try ready-made soil. Add hi Brix or blackstrap for bigger buds.

Or, you can go for something like Complete Crop 9-5-15 for an all-in-one nutrient solution.

Additionally, measure the nutrient and maintain 1.3 millisiemens/meter ^2. Keep the soil light and aerated so it’s well-ventilated and retains some moisture.

Lighting:

Cannabis plants grow faster when they get long and uninterrupted darkness. When the plant enters flowering, ensure 12 hours of complete darkness for the plant. They’ll grow more buds, maximizing your yield

Temperature: 

At all times, maintain the root temperature of your plant at 78 – 80 F. And keep the room temperature at 65 – 85 F. Lower temperature will slow down the flowering of your plants. 

Pot Size:

Pot size is the biggest bet for getting more yield. The bigger your pot size for your plant, the better roots will spread and absorb the nutrients.

Choose 3 gallons of pot at the lowest. However, if you have room, go for 6-gallon pots.

Flowering at 12 Inches Yield

Flowering at 12 Inches will get you about 8 oz. of yield. 12”  is somewhat near the ideal height of a plant when it’s at least 5 to 7 weeks old. The plant’s height really depends on the number of nutrients and light it’s getting.

Remember that all the yields I have mentioned in the article are after drying and curing the buds. Let’s take a glimpse at the factors that will influence your yield.

Nutrients:

Maintain a 50% peat, Silica, dolomite lime, gypsum, and 50% Vermiculite. Manage the pH of the plant to 5.5.

Appropriately water your plants and flush them after week 8 of flowering. So they can focus on growing the buds.

Lighting:

You can use 300W LED lighting for high yield. To get the most out of your light setup, ensure they’re getting 43.2 to 60 micromol/ m^2. D. This intensity of light is the maximum you can get. And it will aid in your plant growth. 

Also, provide pollution-free dark time to your plant. This is the most important fact to get the maximum yield.

Temperature:

Maintain the root temperature of your plant at 78 – 80 F. And keep the room temperature at 65 – 85 F. Lower temperature will slow down the flowering of your plants. Increased temperature can also hamper the flowering process. 

Pot Size:

Bigger size pot will allow your plant to have more room to grow and absorb more nutrients. For a 12” flowering cannabis plant, get a 10-gallon pot or grow bags.

In a bigger pot, the root will grow deeper and provide the plant with more nutrients for photosynthesis. In turn, you will get a bigger harvest.

Flowering at 18 Inches Yield

Flowering at 18 Inches will get you about 18 oz. of yield. 18” is the ideal height of a plant when it’s at least 8 weeks old. The plant’s height really depends on the number of nutrients and light it’s getting. 

Nutrients:

Maintain a 50% peat, Silica, dolomite lime, gypsum, and 50% Vermiculite. Also, manage the pH of the soil to 5.5. 

Additionally, measure the nutrient and maintain 1.3 millisiemens/meter ^2. However, even if you can’t maintain the nutrient in that exact magnitude, try to keep it in that range. 

Appropriately water your plants and flush them after week 8 of flowering. So they can focus on growing the buds.

You can also choose to use cannabis fertilizer to amp up the nutrient supply for your plant. Since your plant is big, it will need more nutrients. 

Do not forget to flush the soil towards the end of the flowering stage. Which is about 8 to 9 weeks.

Lighting: 

To get the most out of your light setup, ensure they’re getting 43.2 to 60 micromol/ m^2. D. This intensity of light is the maximum you can get. And it will aid in your plant growth. You can use different watts of lighting setup to achieve the intensity.

Provide pollution-free dark time to your plant. This is the most important fact to get the maximum yield. The plant grows more in the darkness after the photosynthesis period.

Temperature:

At all times, maintain the root temperature of your plant at 78 – 80 F. And keep the room temperature at 65 – 85 F. Lower temperature will slow down the flowering of your plants. 

Pot Size:

Bigger size pot will allow your plant to have more room to grow and absorb more nutrients. For a maximum 18” flowering cannabis plant yield, get a 15 to 20-gallon pot. It’s safe to go with a 20-gallon pot or grow bag as it gives more room for growth.

In a bigger pot, the root will grow deeper and provide the plant with more nutrients for photosynthesis. In turn, you will get a bigger harvest.

Flowering at 24 Inches Yield

Flowering at 24 inches will get you about 35 oz. of yield. 24” is too big of a length for a plant when it’s just 8 weeks old. The plant’s height really depends on the number of nutrients and light it’s getting.

You must have provided the best nutrients to your plant so congratulations!

Nutrients:

Maintain a 50% peat, Silica, dolomite lime, gypsum, and 50% Vermiculite. Manage the pH of the soil to 5.5. 

Also, don’t forget to maintain 1.3 millisiemens/meter ^2 nutrient level. Keep the soil light and aerated so it’s well-ventilated and retains some moisture.

Appropriately water your plants and flush them after week 8 of flowering. So they can focus on growing the buds.

You can also choose to use cannabis fertilizer to amp up the nutrient supply for your plant. Since your plant is big, it will need more nutrients. 

Lighting:

To get the most out of your light setup, ensure they’re getting 43.2 to 60 micromol/ m^2. D. This intensity of light is the maximum you can get. And it will aid in your plant growth. You can use different watts of lighting setup to achieve the intensity.

There are different stages of cannabis plant growth. This includes providing pollution-free dark time to your cannabis plant. This is the most important fact to get the maximum yield. The plant grows more in the darkness after the photosynthesis period. 

Temperature:

At all times, maintain the root temperature of your plant at 78 – 80 F. And keep the room temperature at 65 – 85 F. Lower temperature will slow down the flowering of your plants.  

Pot Size:

Bigger size pot will allow your plant to have more room to grow and absorb more nutrients. For an 18” flowering cannabis plant, get a 25-gallon pot.

In a bigger pot, the root will grow deeper and provide the plant with more nutrients for photosynthesis. In turn, you will get a bigger harvest.

Flowering at Different Plant Length Yields with Different Strains

Along with the factors discussed above, strains play a big role in cannabis plant yield.

Here’s a table for the yields of popular cannabis strains at different lengths- 

Whatever strain you choose to use, it’s essential to use some specific products that offer better results. Here are some of the nutritious products you might need in the long run-

Now, all that’s left is to get on your feet and start getting the best yield possible!

Frequently Asked Questions (FAQs):

How does Day Length Affect The Flowering Of Plants?

More daylight means more light intensity for photosynthesis. Usually, cannabis plants require 12h of daylight. The more a plant can photosynthesize, the more it will absorb nutrients. Consequently, the plant will get you a higher yield. That’s how the length of daylight can affect a flowering plant.

What Happens At 7 Weeks Of Flowering?

In the 7th week of the flowering phase of cannabis, you’ll notice the biggest changes. The highest production of the trichome on the buds will happen. The leaves will begin to turn yellow. And you’ll notice the amber-brown color around the buds. The buds will also appear more frosty.

What Is A Good Yield Per Plant?

A good yield of a cannabis plant is measured by the wattage of light it’s receiving. For each wattage of light, your plant should yield around 1 to 1.5 grams of dried cannabis bud. Along with wattage, you have to ensure it’s getting enough length of daylight. Growers prefer 12 to 13h of daylight. 

Conclusion

That was my take on flowering at different plant length yields for cannabis plants. More than plant height, the important factor is really the lighting and the nutrients. 

Take great care of your plant during the flowering stage and you’ll get an astonishing yield!

Best of luck!
