Choosing Seeds

Feminized seeds flower and grow weed when they receive less than 12 hours of light per day. Harvest outdoors in fall, or indoors after 15-20 weeks. Professional growers use these.

Autoflower seeds grow small, easy-growing plants that you can harvest in 10-14 weeks. Great for new growers, small spaces, and multiple harvests per season!

How To Germinate

Germination is guaranteed when you soak the seeds in water up to 72 hours in darkness. When it shows a tail, put it in loose soil with fertilizer. Keep it light and damp and a seedling will appear!

Crystal Cannabis seeds grow into strong, resilient plants. The odor is strong, and the buds are absolutely beautiful. Because of its strength, this strain is an excellent candidate for Sea of Green (SCROG) growing techniques. Crystal grows well both indoors or outdoors.

Crystal Strain Origin

Crystal marijuana is a cross between two very notable strains of Cannabis:

The Northern Lights strain is a revered one with no less than eight awards under its belt. It has won first place overall and other renowned awards in the High Times Cannabis Cup. Crystal's other parent, White Widow, is also an honored strain that has also won first place overall and four other rankings in High Times' Cannabis Cup.

Growing Crystal Feminized Seeds

These are feminized seeds. Female plants, contrary to male plants, are the ones that actually produce weed. They start flowering when they receive less light per day, i.e. in the fall or when you manipulate the light cycle indoors.

We advise also reading our germination instructions for guaranteed results.

Crystal Plants

The Crystal strain's parental heritage is quite distinguished, consisting of a blend of Northern Lights and White Widow. Both are favorites among experienced and novice Cannabis growers. Aside from the need to trim these plants, this indica-dominant strain is very easy to cultivate and harvest, even for amateurs and beginners.

When growing this marijuana indoors, these tall weed plants can reach heights of over 3 feet tall. It produces green leaves and dense, large buds, which are covered in glistening crystals (as its name suggests). Upon harvesting, your weed can contain up to a whopping 25% THC.

Best Climate For Crystal Plants

When cultivating Crystal Cannabis seeds outside, the climate should be sunny and warm. Because outside growing gives the plants so much more room to stretch, the plants can grow close to 10 feet tall. Don't worry if you live somewhere a little colder though, these seeds will grow into beautiful plants in temperate climates as well.

We recommend giving your plants:

Flowering and Yield

For optimized results growing Crystal indoors, grow in soil or hydroponic environments. These plants tend to thrive best when the Sea of Green (SOG) growing method is used. They grow vigorously. That means to keep it shaped properly, you'll have to trim the leaves back. Indoor flowering time is about 8 to 10 weeks. Expect to yield 14 oz of usable Cannabis per plant. Outdoor harvesting takes place between late-September and early-October. You can yield up to 16 oz of usable marijuana per plant.

Experiencing The Crystal Strain

Crystal is a hybrid strain of marijuana that produces big, sticky buds covered with red hairs and crystals that glisten right before your eyes. Because it contains some of the highest THC levels, you'll experience a cerebral buzz throughout your body and within your mind.

The effects of this strain are not noticeable immediately. Instead, the euphoria takes a little time to creep up on you fully. But, once it does, you'll experience an intense, invigorating high. It relaxes your body and calms your nerves, making it an effective stress-reliever.

This marijuana strain will uplift your mood while relieving you of any anxiety or stress. The strong buzz is followed by deep sedation and laziness. Crystal Cannabis also stimulates appetites, causing major cases of the munchies, which help intensify these lazy and sedated states.

Crystal Taste and Smell

When smoked, Crystal marijuana gives off a sweet aroma. This tantalizing smell comes with a hint of pine. Some have compared its aroma to that of jet fuel. The strain has a pretty smooth taste. It's piney, with a nice hint of sweetness and notes of fruit, making this strain of Cannabis very pleasing to the palette.

Uses for Crystal

Crystal's versatility makes it a very effective medical marijuana. It has multiple uses and may help individuals with conditions like anxiety, depression, stress, and aches.
