There are two ways to feminize seeds: naturally or by applying chemical substances that force a female plant to pollinate.
Applying colloidal silver to a female plant is the preferred method of feminizing cannabis plants. These chemicals cause the plant to develop pollen sacs without compromising the lineages’ genes.
Why Should You Feminize Your Seeds?

A common fear about feminized cannabis seeds is that they will produce hermaphrodites. If you purchase your seeds from a reputable seller, this fear is misplaced. Early feminizers would purposefully use female plants that were genetically likely to become intersexual. Of course, this meant that those genes were passed down to the seeds. Today, chemicals are applied to the plant without compromising the genetics of the seeds.
As mentioned before, old school feminizers used intersex-prone females to produce feminized seeds. Although there are better methods today, some growers continue to use this one. If you’re purchasing feminized cannabis seeds, be cautious about who you get them from. Find out how the breeder feminizes their seeds to avoid purchasing seeds that are likely to grow hermaphrodites. Even if they don’t become intersexual, there is a risk that a significant portion of the seeds will be male. You can avoid this risk altogether by feminizing the seeds yourself. We’ll explain how to do that below.
Every cannabis strain has its own quality, ranging between high THC, high CBD, high yielding and some can be grown outdoors while all marijuana can grow indoors. High CBD cannabis seeds are often sought after by medical growers growing their own cannabis. The genetics of these strains are focused on gaining as much CBD as we can. However, we do not like to call it medical marijuana, because we are no certified doctors. But, we do recognize the effects and benefits of high quality home growing marijuana. That’s why Nirvana often has cannabis seeds for sale with high CBD values in a special deal. Luckily, Nirvana doesn’t just offer strains with high CBD for marijuana growers with medical needs. We also offer high quality weed seed deals for all of our marijuana strain and sometimes we offer free seeds to help our growers in need. These sales are specifically made for you to tailor your own home growing cannabis needs.
Nirvana’s history can be traced way back to the end of the 1980s. At the time, Nirvana’s founder Mau was working at Positronics, the legendary Amsterdam grow shop. It was here that he attained the knowledge and inspiration to start his own cannabis seed business.
History [ edit | edit source ]
After applying and expanding his knowledge in a number of Amsterdam’s well-known grow shops, the time had come to offer the world the expertise he had gained and the excellent products he had developed.
He spent years travelling, seeking and collecting marijuana seeds from the finest strains available. More years went into experimenting, growing, cross-breeding and developing new cannabis strains, from which the very best were selected for his range of first-rate hybrids.
In 1995 Nirvana was officially founded by Mau. From its origins as a cannabis seed specialist, Nirvana has grown into an innovative business concept. Its unique and original range of carefully crafted hemp products serves to expand the usage of this extraordinary plant further than ever before. While continually improving and extending its range of first-rate cannabis seeds.
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.
This is the least expensive and most privacy conscious way to produce fem seed. CS has gotten a bad name because there is so much bad information spread around about its production and concentrations. It doesn’t help that there are those who believe in drinking low concentration colloidal silver for good health and there is information mixed in about how to produce that low concentration food grade product. Follow the information here and you will consistently produce effective CS and know how to apply it to get consistent results.
There are numerous myths surrounding feminized seeds. Feminizing seeds are a bit more work than simply crossing two plants naturally. However it will save you a lot of time in the end. If you make fem seeds properly then there is no increased chance of hermaphrodites and all seeds will be female. This means no wasted time and effort growing males and it means that all your viable seeds produce useful plants. Since roughly half of normal seeds are male this effectively doubles the number of seeds you have.
Male Isolation Edit
To use the silver, spray on a plant or branch three days prior to switching the lights to 12/12 and continue spraying every three days until you see the first male flowers. Repeated applications after the first flowers appear may result in more male flowers and therefore more pollen. As the plant matures it will produce pollen that can be collected and used to pollinate any female flower (including flowers on the same plant).
Simply construct a generator using a 9-12 v power supply (DC output, if it says AC then its no good) that can deliver at least 250ma (most wall wart type power supplies work, batteries are not recommended since their output varies over time). The supply will have a positive and negative lead, attach silver to each lead (contrary to Internet rumors, you aren’t drinking this so cheap 925(92.5%) Stirling silver is more than pure enough. You can expose the leads by clipping off the round plug at the end and splitting the wires, one will be positive and the other negative just like any old battery. Submerge both leads about 2-3 inches apart in a glass of distilled water (roughly 8 oz). Let this run for 8-24 hrs (until the liquid reads 12-15 ppm) and when you return the liquid will be a purple or silver hue and there may be some precipitate on the bottom.
Auto-flowering cannabis and the easily distributed seed have opened a whole new market in the world of the online grow-shop, making it easy for home growers with shortage of space to grow rewarding cannabis plants in many different varieties. To grow plants indoors, a growing medium (e.g. soil or growing Potting soil, irrigation (water), fertilizer (nutrients), light and atmosphere need to be supplied to the plant.
Sooner or later every grower is going to want to produce marijuana seeds. Developing a new stable strain is beyond the scope of this discussion and requires the ability to grow hundreds or even thousands of breeding plants. However, just about any grower can manage to preserve some genetics by growing f2 seeds where they have crossed a male and female of the same strain, or can produce a simple cross which would be referred to as strain1xstrain2 for instance white widow crossed with ak-47 would be referred to as a WW x AK-47. You can produce some excellent seed and excellent marijuana this way.
