In addition to deciding between indica, sativa, and hybrid, you should also figure out which specific strain you want to grow. If you are not sure which marijuana strain you want to grow, or you’re curious to learn about other strains you might not be familiar with, browse through the digital catalogs of reputable seed banks online and read about the various strains currently available. The best seed banks will have plenty of helpful information.
Buying online may be the simplest way to purchase cannabis seeds. Online retailers often have a larger selection and may provide more detailed information than smaller brick-and-mortar stores.
Indica, sativa, or hybrid?
For the last 50 years of cannabis cultivation, crossbreeding has been the name of the game. As a result, there’s virtually no such thing as a pure indica or sativa anymore. Every seed you’ll consider purchasing is probably a hybrid. Classifying a particular cultivar or strain as indica or sativa usually means that its genetic makeup tends more toward one side or the other of the indica-sativa spectrum.
Once you’ve figured out which seeds are right for you, you need to decide how many seeds to purchase. Regardless of the strain or type of seed, you should have an idea of how many plants you want to grow. It’s also a good idea to circle back to your area’s laws and check the number of plants you’re legally allowed to grow.
At the same time, there are some potential drawbacks to buying seeds online. For one, some weed-legal locations, including the US, still outlaw buying and shipping seeds across state or national borders. There are also issues of reliability. If you want to do business with an online cannabis seed bank, take some time researching the company. Make sure it’s reputable and has good customer reviews.
You can make this yourself by combining worm castings, bat guano, and other components with a good soil and letting it sit for a few weeks, or it can be purchased pre-made from a local nursery or grow shop.
How to set up your outdoor marijuana grow
Heavy clay soils drain slowly and don’t hold oxygen well, so they will need to be heavily amended. A few weeks before you plant, dig large holes where you’ll be placing your weed plants and mix in big amounts of compost, manure, worm castings, or other decomposed organic matter. This will provide aeration and drainage, as well as nutrients for the plants.
Indoor grows can be wasteful, using a ton of electricity to power all those lights, fans, and other equipment. The sun and the wind are free!
Cannabis plants require a large amount of nutrients over their life cycle, mainly in the form of nitrogen, phosphorus, and potassium. How much you need to add to your plants will depend on the composition of your soil.
It also reduces the risk of having a stray male sneak into your crop—just one male can pollinate a huge crop, causing your females to focus their energies on producing seeds instead of buds.
The first couple months of the year is a great time to start planning your cannabis garden to get a head start on the outdoor growing season, which roughly runs from March to November, depending on where you live.
Dispensary staff should be able to give you information on the seeds they’re selling, but keep in mind that a lot of dispensaries focus on selling flower and end-products. It’s a good idea to call ahead and talk to staff to see if they are knowledgeable about seeds and can give you specific information on growing.
Seeds can come feminized, meaning you can just put them in soil and start growing for buds. These seeds are guaranteed to be bud-producing females and growing them cuts out the step of having to sex out plants and discard the males.
Some strains also take longer to grow than others. Depending on whether you’re growing indoors or outdoors, you may want to grow a quicker marijuana strain if you live in a climate that get cold and wet early in the season. For example, indicas are known for having a shorter flowering time than sativas.
Feminized and autoflower seeds will cost more because more breeding work was put in to creating them and they take less time for the grower to get buds.
An inexperienced breeder might cross a male and a female one time and sell the resulting seeds as a new hybrid strain, but professional breeders usually put their strains through several rounds of backcrossing to stabilize the genetics and ensure consistent plants that reflect those genetics.
