indoor outdoor marijuana seeds

Among them, the most important one is the lighting system, which consists of lamps, ballasts and reflectors. Equally important is choosing the right lightbulb, which can be a bit overwhelming considering the array of choice. To this you will have to add the energy cost: during the vegetative stage plants need 18 hours of light and a 6-hour dark period, while the norm for the flowering period is 12 hours of light.

Regardless of the price of the seeds, it comes without saying that indoor set-ups are more costly to install and maintain. When you grow indoors, you can’t do without the systems that replicate the natural light and ventilation conditions, and these tend to be pricey.

Needless to say, in the beginning all cannabis seeds were outdoor seeds. Cannabis is a highly adaptable plant and this has helped the different strains adapt to different outdoor environments. Nowadays, however, cannabis plants can flower in a room or even a tent.

Can marijuana lead to addiction?

In cold regions with short summers, however, it is the autoflowering plants that will produce the best results, as their life cycle won’t be affected by aspects like the moment you choose to grow them.

A ventilation system for temperature control and a filter system that helps keep odours at bay are part of the equation too, yet another thing to take into account when considering indoor growing.

With the above in mind, here at Dinafem you can find a wide range of top-quality seeds both for indoors and outdoors. We have selected three per category based on eligibility, although some of the seeds might be suitable for either of the environments:

If the weather is nice, nature will do all the hard work and produce a good crop, although some watering skills and the ability to properly protect the plants from adverse elements including rain, wind and frosts will also be necessary.

On the other hand, raised beds enable growers to cultivate multiple companion species within the same block of soil. Not only does this enrich the biodiversity of the soil, but it also creates a shield of protective plants that fend off pests while attracting beneficial insects.

The vegetative phase begins once the seedling stage comes to an end. During this time, your plants will focus on photosynthesising and creating energy to fuel development. Expect a flurry of large fan leaves to proliferate throughout this phase. To maintain your plants, you’ll need to consider the following:


Female pre-flowers feature a small bulb and a protruding hair, or pistil. In contrast, male pre-flowers feature a hairless bulb. Remove any males if you’re not looking to create seeds.

Aim to grow plants in the sunniest spot you have access to. Cannabis requires a minimum of six hours of uninterrupted daily sunlight to perform well.

Our Royal Haze Auto brings simplicity to the Haze family! Being an autoflower, she does away with a major inconvenience that growers encounter with photoperiod Hazes—their long flowering time. Instead, Royal Haze Auto moves from seed to harvest in a short 10–12 weeks. She is also a great choice if you want to harvest several Haze crops over one summer season—something you can’t accomplish with photoperiod strains. Get ready for a great smoke with citrus and herbal flavours and a cerebral, uplifting Haze high.

Job number one is to establish how much daily sunlight your cannabis plants are likely to receive during the growing season. Once you know the timeframe you have to work with, you can begin to consider which strains are the best fits. Keep an eye on the local weather forecast and do a little online research. Find accurate data on hours of daily sunlight, sunrise and sunset times, temperatures day and night, prevailing winds, and precipitation frequency.

Genetics hold the key to your cannabis seeds’ potential and that’s a fact. No matter what miracle nutrient formulation you apply or how perfectly you maintain the garden, results will be genetics-driven. If you start with bunko beans, don’t expect huge yields of high-grade. Only by carefully choosing high-quality, feminized seeds can the cannabis grower avoid the low-ceiling limitations of weak genetics. Outdoor cannabis cultivation requires an even more rigorous selection process.


Sour Diesel is another legendary cannabis strain that any “serious” cultivator shouldn’t miss out on growing. With roots in sunny California, she’s well adapted to dry and sunny climates. Here, the plant can grow to its full potential. This 70% sativa can reach a height of 2m and flowers over 10–11 weeks. Despite the slightly prolonged flowering period, she can provide an epic yield of up to 600g/plant. Among her highlights is her trademark fuel-like aroma and taste, which is highly sought-after by cannabis enthusiasts. She provides a relaxing but clear high.

Perhaps you are based somewhere around the Mediterranean. If so, you have the luxury of growing late-blooming sativas outdoors from around April to Croptober. Maybe you are living in Northern Europe and only have a short Spring/Summer 8-10 week window to squeeze in some tough ruderalis. Or you could be somewhere in the middle and need versatile hybrids for a summer crop.

But don’t get too complacent with sativa genetics as they too can succumb to mould and fungus. Check the weather and be at the ready to harvest from September onward should the rain come early. Here are our recommended Hazes to grow in a hot and humid climate:

What kind of cannabis you choose to cultivate and where you sow the seeds will dictate your outdoor crop’s performance. Our breakdown of the perfect strains for each climate zone will help you grow fire marijuana throughout spring, summer, and autumn.
