Blue Dream is one of the most well-known cannabis strains originating from California. The THC range is 17%-25%, with a higher-than-average rate of CBD of up to 2%. 


Blue Dream is popular as it both energizes and relaxes, meaning it appeals to both medical and recreational. It's the perfect strain to assist with pains and for recreational users it offers a happy but not overpowering euphoria.

Genetics: Blue Dream cannabis is the result of crossing Super Silver Haze and Blueberry with most phenotypes holding a subtle balance of 60% Sativa and 40% Indica. 

Flavour: Blue Dream has a sweet berry fragrance and tastes all the way. 
Blue Dream is rich in myrcene which strengthens the calming effects of the strain. It also contains pinene and caryophyllene, which add a spicy hint to the strain. 

Effects: Smoking this strain allows for complete relaxation of the body, however, it will take a lot to get you into a couch lock situation. 

Medicinal: Blue Dreams is popular for soothing issues such as pain, anxiety, nausea, depression, nausea and other conditions that may demand a higher-than-average THC strain.

Side Effects: If you do not have a strong tolerance for THC then Blue Dream can mean you will experience a rapid heartbeat, anxiety or paranoia. Always go slow and low if you are just starting out

Growing: Blue Dream is easy to cultivate! It's a great strain for beginner growers to take and give it a go. 

Flowering: For the best harvest, wait for 9-10 weeks and prepare for an ample yield ranging between 15-20 ounces per square meter indoors.

Tips on Growing Blue Dream indoors

Blue Dream easily adapts to indoor environments. But can quickly reach the six-foot mark so be prepared to do some "topping and training" in the Flowering stage.

Blue Dream plants naturally grow tall and dense so staking them is essential to prevent the plants from leaning over or falling especially when the buds begin to develop and get heavy.

If you plan on growing Blue Dreams repeatedly, keep a grow diary to help with your plant care regime.

Nutrients for Blue Dream

Blue Dream is a hungry plant, it needs its fair share of the primary nutrients: Nitrogen, Phosphorus, and Potassium  (NPK) as well as the secondary and micronutrients including calcium, magnesium, sulfur, Copper, Manganese and Iron.

Blue Dream can consume vast amounts of Nitrogen, in some cases more than twice as much as other strains. 

Using liquid seaweed and molasses can help to maximise nutrient absorption, as can adding mycorrhizae when potting and repotting. Mycorrhizae boosts the ability of the root system to take up nutrients and helps build a healthy strong root system.

pH Levels

Soil pH affects the solubility of nutrients in the soil and how much food the plant can take up. 
Whether growing in soil or coco, the pH should remain between 6.5 and 7.0. In hydroponic settings, your pH should be between 5.5-6.5.

Temperature and Humidity 

Ideally, Blue Dream needs temperatures between 65-85F. When seedlings, the optimal temperature range should be around 75F with a humidity range of 30%-50%. 


After the first few weeks, begin to slightly increase room humidity to around 55%. 


Increase the temperature in the Flower Stage. Blue Dream likes it warm at around 82F. At the same time, gradually lower humidity levels by a few per cent until you are between 30-40%.

Light
Seedlings need 16-24 hours of lighting regime and clones will need 18-24 hours a day. Switch to  18-6 when your plants enter Veg and stick to this schedule until it's time ti flip to Flowering when you want to go 12-12. 


Ensure that you maintain an even distance between the canopy of your plants distance between the canopy of your plants and the light top avoid burning. 

Harvest and Cure

Once you reach 9-10 weeks you are ready to Harvest and Cure your product. Remember that despite how well you have grown your plants a good yield can be made or broken by how you carry out your harvest and cure so remember to follow a thorough plan and don't rush it, no matter how bad you want to sample your crop. Do this last stage right and you will be enjoying the delights of Blue Dream for weeks to come.
