A male plant or a plant with male flowers will pollinate your entire crop rendering it seedy. You probably don’t want THAT many seeds so how can you avoid it? Moving the male to another room might work but if that other room shares an air path via ducting or air conditioning then pollen may still find its way. One technique is to construct a male isolation chamber.
Other times you will have no choice but to produce feminized seed because it will be a female plants genetics that you want to preserve and you won’t have any males. Perhaps you received these genetics via clone or didn’t keep males.
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.
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).
Auto-flowers have been rising in popularity fast and there are now auto flower growers communities. These Web properties allow users to get information on how to grow these non photo-sensitive plants and what are the best practices when producing and germinating auto-flower seeds.
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.
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.
In nature, a severely distressed female cannabis plant will naturally become a hermaphrodite and produce pollen sacs in order to self-pollinate. This is a survival mechanism built into all female plants, but it is only triggered when the future of the plant’s lineage is compromised. Consequently, many of the resulting seeds will be naturally selected to be intersexual, and that can make for a disastrous breeding situation. A hermaphrodite can pollinate with female plants that are meant to be harvested, causing the buds to stop developing and to produce seeds.
Imagine putting in the work to nurture a small 6 plant garden to find that only 3 of the plants you’ve cultivated produce buds because they’re male. If this sounds like a disappointing waste of time to you, you should feminize your seeds. Unless you are hanging on to male plants in order to develop a robust breeding program, male cannabis plants waste space and resources. Using feminized cannabis seeds removes the risk of unwanted pollination causing seedy buds or the possibility of growing flowerless male plants.
When it comes to cannabis plants, females are the only sex that can produce buds. Feminized cannabis seeds grow plants that are exclusively female and can almost guarantee that every plant that sprouts from their shells will flower. Normally, a male cannabis plant will pollinate a female plant, and that is how seeds are produced. The resulting harvest of regular cannabis seeds will contain about half male and half female seeds. For the flower producer , this is a costly inefficiency. Roughly half of an entire grow can be tossed at harvest time if the seeds are not feminized.
Why Should You Feminize Your 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.

There are two ways to feminize seeds: naturally or by applying chemical substances that force a female plant to pollinate.
The other reason to avoid feminizing plants the natural way is that it increases the likelihood of producing weak strains. When a female plant has been so compromised that it resorts to a sex change in order to survive, it is an indication that the plant’s genes are not strong enough to withstand the threats posed to it by its environment.
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.
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.
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.
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.
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.
