BRICK WEED: ARE THE SEEDS GOOD TO USE?

Did you know that the seeds found in brick weed can be a great school in growing cannabis? The interesting thing is thinking that the seeds found can free you from having to smoke this marijuana in bulk.

Those who follow the blog must be aware of our cultivation series, in which we cover all the necessary steps to plant your cannabis and keep the plant healthy. And we know that access to the famous brick weed is super common, especially here in Brazil. And there are people who find a lot of seeds inside it and ask themselves: “can I plant it?”.

The answer is yes!

And let us tell you something important: brick weed seeds are a great “school” for starting cultivation. You can use these seeds if you want to grow, mainly because access to other seeds (from specific strains) can be more complicated – and more expensive – here in Brazil. Knowing how to differentiate good from bad seeds and dealing with them with care and love, it can become a beautiful plant, full of buds and really healthy.

Here in this post, we will tell you the main care you should take with her. Let’s learn?

Good seeds and bad seeds

In our step-by-step on germination, we have told how the seed selection process takes place. With brick weed seeds, you have to be extra careful: it is very easy to find seeds, but they will not always grow. So as soon as you find and collect your seeds, do the following test to separate the good and the bad:

Apply a little pressure to the skin;

If it breaks easily, the seed is no longer good for planting.

If it doesn’t break, it is perfect to go to the germination phase!

Another indication that a pressed seed is good is its color. If it is dark brown, with a good shine and some lighter patterns, it is usually perfect for germinating. If it is white or green, weak, it may be dry or not mature.

Test with water: another good way to know if the seed is in good condition is to leave it in the water for 24 hours, in a dark and not too cold place. If they go to the bottom of the glass, they are healthy. If they don’t, give them a little push – if they don’t go down anyway, you can throw it away – this baby won’t make it.

You can leave the seeds germinating in the water itself, or go for the paper towel method.

For this method, you will need:

Two clean dishes;

Step 1:

Take two paper towels and place them on a plate. Then place the cannabis seeds at least an inch apart and cover them with the remaining two sheets of paper towels soaked in water.

Step 2:

To create a dark, protected space, take another plate and turn it over to cover the seeds (like a dome).

Step 3:

Check that the area in which they are kept is warm, between 20 and 30 ° C.

After these steps, it’s time to wait! Don’t forget to check the paper and make sure it is still wet. When it is drying, add more water with a spray bottle.

Some seeds germinate very quickly, while others can take several days. You know that a seed germinated when the seed separated and a single little sprout emerged from it.

So, is it male or female?

As brick seeds are basically regular seeds, we have no way of knowing whether they are male and female until they develop and it is possible to see their reproductive organs. Yeah, friends, biology is important, you see? We will show you how to identify these beauties. (put images and point the difference with little arrows)

Female cannabis has what appear to be hairs, which are the pistils.

Male cannabis begins to develop marbles, which are its pollen bags.

Jeez, it’s a male. What do I do now?

If you aren’t familiar with this process, we will explain to you: the female plant is the one that gives flowers, and that will produce beautiful buds for you. But male cannabis. Ah, them males… they can kinda ruin your goal to get extra good buds.

When we have a male and he pollinates the female plants, they turn their energy to produce more seeds, and less flowers. This can happen even if a neighbor grows cannabis nearby: pollen from the male plant can travel long distances and create seeds in the buds of others.

So, our guideline is: throw the male away! For the love of buds.

What strain is this?

It is practically impossible to tell the strain of your press plant. That’s because it usually comes from plants that are grown only to be trafficked by Latin America, in several different places, in different ways and with seeds and characteristics that can change with each harvest.

However, you can identify whether it is more sativa or more indica by looking at the characteristics.

Normally, the pressed seeds are more sativa, plants are thinner and have more aerated buds. It is worth remembering that the brick seed’s flora time is usually longer.

The profile of cannabinoids, production of trichomes, profile of terpenes and other characteristics is more difficult to know, but they can be observed and perceived throughout the flora and after harvest.

So, ready to plant your brick weed seed? We guarantee that, with a lot of love and care, they can be wonderful! In addition to that you will be stopping consuming bricks, which can come full of debris, and you will not be contributing to the traffic.

It’s funny to say that, but maybe a brick weed seed that will save you from having to smoke brick cannabis!

Hands to the ground!

To learn more, follow our cultivation series! We will bring even more information on how to give the best care to your plants.

Weed seed contamination in imported seed lots entering New Zealand

Imports of seeds for sowing are a major pathway for the introduction of contaminant seeds, and many agricultural weeds globally naturalised originally have entered through this pathway. Effective management of this pathway is a significant means of reducing future plant introductions and helps minimise agricultural losses. Using a national border inspection database, we examined the frequency, origin and identity of contaminant seeds within seed for sowing shipments entering New Zealand between 2014-2018. Our analysis looked at 41,610 seed lots across 1,420 crop seed species from over 90 countries. Overall, contamination was rare, occurring in 1.9% of all seed lots. Among the different crop types, the arable category had the lowest percentage of seed lots contaminated (0.5%) and the forage category had the highest (12.6%). Crop seeds Capsicum, Phaseolus and Solanum had the lowest contamination rates (0.0%). Forage crops Medicago (27.3%) and Trifolium (19.8%) had the highest contamination rates. Out of 191 genera recorded as contaminants, Chenopodium was the most common. Regulated quarantine weeds were the rarest contaminant type, only occurring in 0.06% of seed lots. Sorghum halepense was the most common quarantine species and was only found in vegetable seed lots. Vegetable crop seed lots accounted for approximately half of all quarantine species detections, Raphanus sativus being the most contaminated vegetable crop. Larger seed lots were significantly more contaminated and more likely to contain a quarantine species than smaller seed lots. These findings support International Seed Testing Association rules on maximum seed lot weights. Low contamination rates suggest industry practices are effective in minimising contaminant seeds. Considering New Zealand inspects every imported seed lot, utilises a working sample size 5 times larger than International Seed Testing Association rules require, trades crop seed with approximately half of the world’s countries and imports thousands of crop seed species, our study provides a unique overview of contaminant seeds that move throughout the seed for sowing system.

Targeting Weed Seeds at Harvest

As herbicide-resistant weeds become more common across the country, researchers and growers are looking for other ways to control weeds.

In Colorado, they’re looking to techniques and technology developed in Australia, which has significant issues with herbicide-resistant weeds.

Known as harvest weed-seed control, these IPM-friendly methods are designed to destroy or remove weed seeds during harvest to prevent them from raining down onto the soil and replenishing the weed seed bank. In Colorado wheat, weed species of concern are winter annual grasses that share the grain’s growing cycle, like jointed goatgrass, feral rye and downy brome.

“In harvest weed-seed control, the objective is to prevent those seed-bank increases,” explained Colorado State University doctoral candidate Neeta Soni. “There are a number of ways to do it, and we’re investigating to see if they could be adopted in Colorado.”

One way to destroy the weeds seeds is by directing chaff during harvest into a cage mill – imagine a giant coffee grinder – and pulverizing the chaff and weed seeds into powder. That’s the idea behind an Australian innovation known as the Harrington Seed Destructor (and a new competitor called the Seed Terminator).

Another option is to use a piece of equipment called a chaff deck to gather chaff into mounded strips behind the harvester, capturing the weed seed in those mounds of chaff. In some places those chaff strips can be burned, and in others they’re left alone to allow the weed seeds to decay without entering the soil.

A third option is to use chaff carts and collect all the chaff and captured weed seeds for off-site destruction.

“Our research is focused on finding out if there is potential to use these methods in Colorado,” explained Soni, a graduate student of assistant professor Todd Gaines. “So what we needed to know is whether, at harvest, the majority of the winter annual grass seeds are retained in the upper wheat canopy, where they would be vulnerable to the seed destructor or other methods.”

If the weed seeds have already shattered and fallen to the soil, or if the weed seeds are below the cutting height of the combine, the methods would not be as effective.

So the Weed Research Lab team measured and counted a lot of weeds.

“What we found is that the majority of seeds are still retained at harvest,” Soni said. “Downy brome is the same height as wheat, rye is taller and jointed goatgrass a little shorter, but growers could adjust their cut height to manage it.”

Soni then counted out 1,000 seeds of each weed species into a specified amount of chaff and drove to the University of Arkansas where they have a seed destructor set up on a test platform. She ran each bundle through the destructor. The pulverized material was dusted across beds of soil to see if any weed seeds germinated. Virtually none did.

“The seed destructor was 98 percent effective on downy brome and jointed goatgrass, and 99 percent effective on feral rye,” Soni said.

The Gaines lab hopes to conduct field trials with the equipment. They will also study if the strips of mounded chaff are effective in Colorado, or if the state’s dry and windy conditions enable weed seeds to survive and spread.

The seed destructor isn’t commercially available in the United States yet, but a number of researchers are testing versions in different regions and in different crops. The initial model was a tow-behind trailer, but both Australian manufacturers now offer the technology integrated into a combine harvester that retails between $120,000 and $160,000 Australian dollars.

Not every grower would need to buy one.

“It is very common that growers here have their harvesting done by a contractor,” Soni said, “so this could be an extra service they provide.”

But not at every harvest. Because whatever specific iteration of harvest weed-seed control Colorado growers may eventually adopt, it should be just one element of an integrated management strategy, Soni cautioned.

“Repeated use could lead to the selection of earlier-shattering weed seeds, or shorter weeds,” she said. “It has to be used in rotation with other integrated measures, including herbicides and crop rotation.”

In short, it should be part of an IPM program.
