There are two ways of growing marijuana plants namely cloning them and growing them from the seeds. Here at Sunwest Genetics recommend growing them from the seed as we offer the best cannabis seed for sale in the market here in the USA.

Is it better to grow it from the seed?

There is no best way than do it the natural way. Compared to cloning marijuana plants that are grown from the seed are significantly stronger and produce higher-quality genetics. Therefore, it is best to grow it from the seed but there are also disadvantages as you need to take proper care of every seed you grow to guarantee that the cannabis seed will mature and produce yields.

How to grow marijuana from seed?

The process of growing marijuana from seed involves four main stages: the germination stage, during which the seed makes its first sprout and emerges from the planted medium; the seedling stage, during which the seedling develops into a small plant with tiny leaves and is extremely sensitive to its environment; and the vegetative stage, during which your plants start to grow bigger and stronger by gaining a lot of mass from the leaves, roots, and stem. The flowering stage, which is the last and most crucial of all, is when your plants will produce buds and be harvested. Keeping in mind these four stages will make cultivating your very own marijuana hassle-free.

Indoor or outdoor cultivation which is better?

Whether to grow your cannabis seeds indoors or outdoors depends on various factors. Now let’s consider the pros and cons. Growing plants indoors involves a lot of attention because the right humidity, airflow, and local climate must be created for the plant to be able for it to flourish. However, growing marijuana indoors is safer and gives you more options when it comes to selecting cannabis seeds. On the other hand, selecting marijuana seeds that can flourish in your region is necessary if you plan to cultivate your plant outdoors. Your options will be fewer, but because it requires little maintenance, it is quite cost-effective. you don’t need to establish your local habitat because mother nature will take care of that for you. Additionally, depending on your area, you should make a strategy for what month you will grow your weed seeds.

What is the difference between Indica, Sativa, and Hybrid strains?

What effects do I want to achieve? is the major factor to be taken into account while selecting a strain. It is crucial to understand whether a cannabis strain is Indica, Sativa, or hybrid. We’ll start with Indica because it’s the best cannabis strain for people who want to unwind and reduce stress. This strain has a body-high effect, which can help you unwind and have a better night’s sleep. The Sativa strain is best for you if you want the energetic benefits and want the contrary. The Sativa strain of marijuana provides both an anti-anxiety effect and a “head high,” which is an energizing and creative sensation. Because of its cannabinoid concentration, it can also be used medicinally as a hallucinogen, analgesic, sedative, and anti-inflammatory medication. Last but not least, the hybrid cannabis kind is the ideal option if you want the best of both worlds. You can experience both the calming effects of Indica and the stimulating effects of Sativa. Choose the ideal strain for you and benefit from it.

What marijuana seeds should I buy and grow?

We have already talked about how to choose the best cannabis seeds and their effects. We’ll now take into account your goals for developing these seeds and your level of seed-growing experience. If you desire high THC or CBD levels, you should first think about the potency of the seeds because there is usually a trade-off between the two. So, high CBD cannabis seeds are the best option if you want to utilize them for medical reasons. Next, consider your level of experience as a farmer; if you’re just getting started, start with autoflowering seeds because they’re simple to grow and ensure success with little work. However, if you are an experienced grower, pick and choose the best strain to produce. Another is that feminized weed seeds are best if you want big yields, in which case you would only want female cannabis plants. Because it exclusively generates female plants, your harvest will increase. These are just some things to take into account and you will find out more if you buy marijuana seeds here at Sunwest Genetics and start your journey by cultivating and reaping the rewards.
