This can be used as is, or you can cut a small intake in the bottom to improve airflow. Pollen won’t be able to escape the intake as long as the fan is moving but you might put filter paper over the intake to protect against fan failures. You can also use grommets to seal holes and run tubing into the chamber in order to water hydroponically from a reservoir outside the chamber. Otherwise you will need to remove the whole chamber to a safe location in order to water the plant or maintain a reservoir kept inside the chamber.
A male isolation chamber is simply a transparent container such as a large plastic storage tub turned on its side (available at your local megamart). Get a good sized PC fan that can be powered with pretty much any 12v wall adapter, by splicing together the + (yellow or red on fan, usually dotted on power adapter) and the – wires (black on fan, usually dotted power adapter) just twist with the like wire on the other device and then seal up the connection with electric tape. Then take a filtrate filter and cut out squares that fit the back of the pc fan so that the fan pulls (rather than pushes) air through the filter. Tape several layers of filter to the back of the pc fan so all the air goes through the filter. Now cut a large hole in the top of the plastic container and mount the pc fan over top of it so it pulls air out the box. You can use silicon sealant, latex, whatever you’ve got that gives a good tight seal.
There are a number of important characteristics when selecting parents. First are you making fem seeds? If you are then both parents will be female. This makes things easier. If not then the best you can do is select a male with characteristics in common with the females you hope to achieve from the seed.
Making Feminized Seed Edit
Stress techniques will work but whatever genetic weakness caused the plants to produce a male flower under stress will be carried on to the seeds. This means the resulting seeds have a known tendency to produce hermaphrodites. Fortunately, environmental stress is not the only way to produce male flowers in a female plant.
To pollinate a plant you can brush the pollen on a flower with a cotton swab or you can take the plastic bag, then wrap the flower inside it and shake, trapping the pollen inside for easier transportation. In this way you can selectively pollinate plants and even individual buds and branches.
Silver Thiosulfate is a substance that has similar principle, application and results of CS, but is more difficult to make. STS is more difficult to acquire, but it can still be obtained directly from a chemical supply company. STS is not an expensive or controlled substance.
Obviously potency, yield, and psychoactive effects are critical to the selection process. But some other important traits are size, odor, taste, resistance to mold and contaminants, early finishing and consistency.
What to look for when buying feminized seeds?
When ultimately deciding where you want to purchase your seeds it is important to look for a few things. Well established trusted seed companies will generally offer a warranty for their seeds. With the high cost that is often associated with feminized seeds it is important to view your purchase as an investment, and when able it is best to go with the highest quality possible to ensure the best results. You will usually get the best deal when purchasing in bulk. There are other things to consider, like the offered variety of strains, the THC and CBD content available, and of course the cost. Sometimes it is best to go local, so the shipping doesn’t kill you. Other times, you will find the most variety over the border in which case it might be worth a little extra.
How are feminized seeds made?

Usually, a cannabis seed offers a 50/50 chance of producing either a male or female. This is something biologically programmed into the DNA of the plant to ensure the highest odds of reproducing and of course, overall survival. Much like with humans, the gender is determined by the X and Y chromosomes. A plant with one of each chromosome will 99% of the time produces a male. A cannabis plant with two X chromosomes with hasa 99% chance of being female. To create feminized seeds, a treatment of colloidal silver is sprayed on the plants during the flowering stage. This process is used to transform female plants into hermaphrodites (a plant that is both male and female). It forces them to grow seed sacs full of female pollen instead of bud. Those sacs can then be collected and used to pollinate other female plants. Since this process makes two females the mothers, the plant will produce seeds that will only carry X chromosomes. This ensures a 99% success rate of female only plants. While in nature this process does on occasion happen it is incredibly rare, and when it does those plants will also almost always produce more seed that will create hermaphrodites, than seed that is strictly female.
What’s the deal with feminized seeds? Why are they so expensive and what exactly does feminized mean? Feminized cannabis seeds are genetically modified seeds and will produce only female plants. There is quite a bit of science behind how feminized seeds are made. Making feminized seeds isn’t something the average person does. It is a long process that is time-consuming. If your buddy says he’s created some in his basement and has them up for sale for half the price of your local seed bank, I’m not entirely sure I’d risk buying any. The process of making feminized seeds is generally done in a lab in a strictly controlled environment but can be recreated by a careful and patient grower.
Finding trusted seed vendors can be more difficult than it sounds. Even the sketchiest companies will plaster “trusted” across their site like a badge of honor, but that doesn’t necessarily make their statement true. To help, we have compiled a list of the highest rated top three seed vendors that ship to Canada and carry a wide range of feminized seeds that are sure to impress.

1. What color is it?
If your marijuana seeds boast darker color patterns with visible veins, then it’s a good indicator that they may be of good quality.

5 reasons why you should try eating cannabis seeds
To best preserve cannabis seeds, you will need to store them in a dark, cool, and dry area. These babies may be dormant, but they are still very much alive and need to be treated with the utmost care. Marijuana seeds will deteriorate quickly when exposed to heat, humidity, dramatic temperature drops, or rough handling, so storage in a fitting or soft-lined container in a cool (not cold) dark space is ideal.
These seeds are specifically designed to create only female cannabis plants. Feminized seeds are selectively bred among themselves to produce a seed that has a 99% chance of resulting in a female plant. Since females are generally the only type of cannabis plant that anyone wants, these seeds come at a higher cost but also a significant benefit.
Only federally and provincially approved vendors are legally allowed to sell cannabis seeds, so it is important to research a provider thoroughly before placing an order. That means your options are relatively limited for buying, but marijuana seeds can be traded or gifted legally, so a great alternative option is to join a seed exchange program where you can connect with other like-minded individuals and legally trade products.
