Learning Made Easy

Dummies has always stood for taking on complex concepts and making them easy to understand. Dummies helps everyone be more knowledgeable and confident in applying what they know. Whether it’s to pass that big test, qualify for that big promotion or even master that cooking technique; people who rely on dummies, rely on it to learn the critical skills and relevant information necessary for success.

Growing marijuana takes a certain level of commitment: time, energy, and financial resources, so be sure you can commit to the whole process.

With cloning, you don’t have to get new seeds every time you want to grow another plant—you just take a cutting of the old plant—and you don’t have to germinate seeds or sex them out and get rid of the males.

For the typical homegrower, it may be easier to obtain cannabis seeds rather than clones. Growing from seed can produce a stronger plant with more solid genetics.

Was the seed found in good weed?

Germinating cannabis seeds doesn’t always go as planned. Some seeds will be duds. Others will be slow and take longer to sprout. But some will pop quickly and grow rapidly.

Autoflowers can be started in early spring and will flower during the longest days of summer, taking advantage of high quality light to get bigger yields. Or, if you get a late start in the growing season, you can start autoflowers in May or June and harvest in the fall.

One way to avoid sexing plants is to buy feminized seeds (more below), which ensures every seed you plant will be a bud-producing female.

If growing male and female cannabis seeds, they’ll start to show their sex organs, or “pre-flowers,” after 8-10 weeks from germination.

Growing cannabis in your home is legal in an increasing number of states and provinces throughout the United States and Canada. To make starting a home garden easy, growers can start with feminized seeds for many popular strains from providers like Kannabia.

As a result, growing cannabis from regular seeds isn’t very efficient—it’s akin to running a bakery that has to throw out every second loaf of bread. Growers working from regular seeds have to account for the fact that roughly half of their plants could be males. While those plants are of some value to breeders, folks growing for flower won’t find much to like in them, and too many male plants can spoil a grow.

How Are Cannabis Seeds Feminized?

There are numerous advantages for growers who start their garden using feminized seeds. By removing the guesswork of germinating regular seeds, feminized seeds streamline the growing process, saving space and time.

Cannabis plants that are pollinated naturally or with traditional breeding techniques can produce both male or female seeds. These are known as regular seeds and, as in most species, they occur with about an even split between the two sexes. That means cannabis cultivators starting with standard seeds have about a 50% chance of yielding a female plant from each one.

Both substances are a blend of water and fine silver particles, and they work in largely the same fashion. The silver solution impedes the production of ethylene, a hormone involved in flowering. The result is a female plant, but one that produces male flowers with pollen sacs. Since those pollen sacs develop on a plant with only female genetics, female genetics are all they carry. When those flowers pollinate another female plant (one untreated by silver solutions), the resulting seeds are nearly certain to be female.
