Unicorn Poop

Unicorn Poop is a very recommended strain for medical purposes due to its powerful sedative effects and physical relaxation that this GMO Cookies x Sophisticated lady cross provides thanks to its high THC levels. Besides, its citrus, floral notes along with the slight coffee undertones would be ready to taste in just 8-9 weeks of flowering. Definitely a magic strain.

Hollands Hope

The main particularity and some of the most valued characteristics of these plants, especially for beginners, is their high resistance against fungi plagues. Thus, in regards to the growth, this strain can grow up to 2 m (6.5 ft) tall, so you’ll need to watch that your plants don’t touch your indoor lights. On the other hand, its demolishing effects and sweet, intense fruity flavors and aromas make it a very interesting strain to try.

Harlequin CBD

Harlequin CBD by GB Strains is the medicinal result of a cross between Harlequin x OG Kush CBD with high levels of this beneficial cannabinoid. This is the perfect strain for patients looking for a treatment for their muscle cramps, insomnia problems or anxiety disease. However, this plant tends to over fertilize, which is not suitable for beginner growers.

The best selection of sativa weed seeds for indoor growing

Cannabis sativa plants contain large amounts of THC, a very powerful compound that produces potent mental effects.

Kali 47 by Advanced Seeds is a long growth period strain that will reward your patience with lots of dense, aromatic buds. This aroma has a citrus scent with a caramel-like flavor that will definitely melt in your palate.

Critical Jack

Critical Jack was born from the Critical+ x Jack Herer cross, two of the most famous varieties of the cannabis industry. This awesome plant has inherited the best of the both worlds of its parentals. On the one hand, it has a high yield and fast flowering, producing dense buds like the Critical+; and on the other hand, it has an elevating psychoactive effect that has been inherited from the Jack Herer, along with a great resistance to fungi and rot diseases.

What are indoor marijuana seeds?

Indoor marijuana seeds have been developed to be grown indoors, as this is one of the most popular ways to grow high-quality and potent cannabis plants. However, this doesn’t mean that you cannot grow these seeds outdoors, but the final yielding may not be as good as the intended one, and even the chances of failure are increased.

What are the advantages of growing indoor cannabis seeds?

Although growing outdoors is much cheaper than indoors crops, there are some advantages of growing indoor cannabis seeds that you should know if you are interested in starting to invest indoors:

• You can monitorize your plants more efficiently as you have full control over all the essential parameters that plants need to properly grow (humidity levels, amount of light, nutrients, temperature, etc.).
• You can also choose when to start the flowering period as you can control your plants' photoperiod.
• You avoid most plagues and pests that often occur in an outdoor environment.
• You can have more than one harvest per year, unlike the outdoors growing.
