What are “feminized” cannabis seeds and how are they different from regular seeds? (Where can I get feminized seeds?) Feminized cannabis seeds are produced in a way to make sure that all the resulting plants are female (since only female cannabis plants make buds). “Regular” (or non-feminized) seeds will produce about half male, and half female plants. Having male plants can be an asset to a breeding program, but having to watch over and throw away half the plants can be a waste of time and space for growers who just want to grow their own supply of bud! By starting your grow with feminized cannabis seeds from a reputable breeder, you can stop worrying about plant gender altogether, and know that every single one of your plants is going to be female and make buds! All plants end up producing buds Less wasted space on plants that need to be thrown away Don’t need to watch plants closely to make sure you remove males No chance of pollination without pollen sacs, so no seedy buds. In order to build a robust breeding program and create new strains, you should start with regular seeds so you have both male and female plants It’s possible to buy feminized seeds from bad breeders which turn into problematic hermies (mixed gender plants) or even just end up being half male plants like regular seeds.
That’s why it’s important to order seeds from a trustworthy breeder! Since I started growing cannabis nearly a decade ago, I’ve only grown with feminized seeds! I’ve never had a single plant that didn’t grow buds! Non-Feminized Seeds Produce Half Male, Half Female Plants (learn more more about cannabis plant gender) Feminized Seeds Only Produce Female Plants. The way breeders create feminized seeds is they breed two female cannabis plants together, which means that all the resulting offspring will be female. This is done by spraying developing flowers with a substance that changes flower development (often colloidal silver or gibberellic acid). This process is used to force one of the female plants to start producing pollen sacs just like a male plant. By harvesting the pollen sacs and using the “female” pollen to pollinate buds of a different female plant, you are giving the resulting seeds only female genes (there is no “father”), so none of the seedlings end up being male. How To Make Feminized Cannabis Seeds Like The Pros. Growing from feminized cannabis seeds is a space and resource-efficient way of getting all girls, all the time. Find out how to create your own feminized cannabis with Royal Queen Seeds. Growing cannabis is all about resinous flowers, trichomes, and rich cannabinoid profiles. These splendid characteristics can only be found on the female flowers. Having gardens full of robust, un-pollinated sinsemilla females means jars full of mind and body-friendly, crusty nuggets. The only bummer, unless you grow from clones, is that cannabis is wired to produce about 50% male seeds and 50% females. Wouldn’t it be sweet if it was possible to grow all females from seed, every plant, every time? Well, that is where the feminizing technique comes into play: two methods of manipulating the cannabis plant to produce only females from seed, every-time. But 99% of the time is a pretty good number, and could be considered entirely male risk-free. The general practice behind feminization is that female plants are forced to produce pollen, which is in turn used to pollinate other female plants. Resulting seeds will be feminized, with no risk of further pollination. Feminized seeds are super efficient for indoor and outdoor gardeners. Area, time, and resources aren’t being given to plants that will be thrown away two weeks after the 12-12 flip. Similarly, outdoors where a large plant can consume a lot of time and resources in upkeep prior to the autumn show of flowers, feminized plants are also a good way to reduce guerrilla crop pollinating. There’s nothing worse than bush-bashing out to a well-hidden crop only to find a rogue male or two have impregnated every female plant. “Applications that reduce the ethylene level in tissues or antagonise the action of ethylene causes the formation of male flowers instead of female ones” — Paraphrase, Byers et al., 1972.
There are a number of solutions that can be sprayed on female plants to create male pollen sacs: benzothiadiazole, gibberellic acid, silver thiosulphate, silver nitrate, and colloidal silver. Colloidal silver is by far the easiest to source or make. It is non-toxic, non-caustic, and can be bought from a pharmacy or easily online. The other solutions can be dangerous, difficult to get a hold of, and expensive—except gibberellic acid, which can be found in nurseries, but is not as effective as colloidal silver. But if you want to watch some freaky plant growth just for the fun of it, give gibberellic acid a try. It is a growth stimulant and makes plants stretch and stretch. Colloidal silver is a distilled water-based solution in which microscopic particles of silver are suspended. The nature of colloids means the particles will never settle out and can’t be removed by normal filtering. Colloidal silver is available commercially, or you can make your own if you want to totally geek out (see how-to section at the end).
For example, it is used to soothe burns, as an antiseptic and digestion stimulant in people, and as a fungal control in horticulture.
