The law is the first thing to take into consideration when planning to grow cannabis. Before doing anything else, double and triple check the laws in your area related to purchasing cannabis products and growing weed at home. This is important because the legal status of both cannabis products and home cultivation will dictate where and how you can buy cannabis seeds.
Growing indoor seeds gives you the ability to control and fine-tune the growing climate for your plants. You may feel more confident trying new seeds or difficult cultivars because you can adjust the environment as needed.
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.
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.
Remember, seeds must be germinated before planting and there is no such thing as an iron-clad germination guarantee. Always plan on a certain percentage of seeds failing to germinate or growing into weak, unviable plants. So plan on purchasing more seeds than you think you will need. As a general guideline, assume that at least 25% of the seeds you plant will, for one reason or another, not make it to harvest. For best results, buy and plant 25% more seeds than the number of mature plants you want to produce.
On the other hand, feminized seeds have been bred to produce only female cannabis plants. For many growers, these are the best cannabis seeds to use. One reason is that using feminized seeds means you won’t need to buy quite as many because a higher percentage will grow into female plants. However, feminized seeds are not fool-proof, and there is no fully reliable germination guarantee, so you should still pay attention to the sex of your plants as they mature so you can spot and eliminate any males that might pop up. In general, feminized seeds are easier and more straightforward to grow.
Because US federal law still prohibits cannabis, it can be hard to find information on seed banks and breeders. Breeders who have a long history and positive reputation are usually a good place to start. To get an idea of what well-established breeders look like, check out:
When growing regular seeds, some won’t germinate and some will have to be discarded because they’ll turn out to be males. With feminized seeds, some won’t germinate, but a higher percentage of them will turn into flowering plants because there won’t be any males.
How to buy cannabis seeds at a dispensary
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.
Navigating the cannabis seed market can be challenging when states have different degrees of legality. This guide will answer your questions on buying seeds so you can be on your way to growing your own cannabis.
CBD, or cannabidiol, is one of the chemical components—known collectively as cannabinoids—found in the cannabis plant. Over the years, humans have selected plants for high-THC content, making cannabis with high levels of CBD rare. The genetic pathways through which THC is synthesized by the plant are different than those for CBD production.
In commercial cannabis production, generally, growers will plant many seeds of one strain and choose the best plant. They will then take clones from that individual plant, which allows for consistent genetics for mass production.
Go easy on nutrients
In some cases, even if a seed isn’t completely mature, there’s still a chance it could be viable. But often these are extremely weak, take long to develop, and express other unfavorable characteristics. Growers usually discard weak plants to free up space.
As interest in CBD as a medicine has grown, many breeders have crossed high-CBD hemp with cannabis. These strains have little or no THC, 1:1 ratios of THC and CBD, or some have a high-THC content along with significant amounts of CBD (3% or more).
If growing outside, some growers prefer to germinate seeds inside because they are delicate in the beginning stages of growth. Indoors, you can give weed seedlings supplemental light to help them along, and then transplant them outside when big enough.
