Tips for growing Blue Dream cannabis

This article is presented by Advanced Nutrients, a global company raising the bud weights and reputations of cannabis growers since 1999.


Strain overview: Blue Dream is a hybrid cross between Blueberry and Haze. It is deemed the most popular cannabis strain based on reviews and widespread availability. Blue Dream’s popularity stems primarily from its sweet berry fragrance and even-keel effects that entice both connoisseurs and first-time consumers.

Grow techniques: Sativa-dominant genetics ensure that Blue Dream will grow tall. With proper pruning and training, this plant will grow beautifully and easily. Give Blue Dream plenty of trellis support as the sativa structure has a hard time supporting heavier indica-like buds. Blue Dream is known for its ability to grow high yielding plants in quality soils.

Flowering time: 9 to 10 weeks

Yield: High

Grow difficulty: A vigorous plant that allows for a large margin of error, Blue Dream is an easy strain to cultivate.

Climate: Thrives in most climates and handles cold nightly temperatures well. Blue Dream’s ideal temperature ranges between 65-85 degrees Fahrenheit.

Indoor/outdoor: Can be grown successfully both indoors and out. Blue Dream is best known for its successful growth outdoors in California, but transitions easily into indoor environments. Consider topping and training to prevent Blue Dream from outgrowing your indoor space. 

Feeding: Heavy feeding. Blue Dream can take high levels of nitrogen without burning.

    I finished Blue Dream successfully in SW Oregon, very small amounts of mold, finished about a week before Halloween, in a greenhouse. Had a bumper crop, won’t need to grow that strain this year, maybe again next year. Great stuff!

    HI there,
    I live in Oregon and I got my very first clone.
    I have a tent and a LED grow light. However, my plant is not growing!!
    It looks good, but it is stuck at around 15 inches, Any ides?

    Thank you in advance!

      Have a look at ventilation and nutrition. if the plant is not getting enough CO2 , i think it would be hard to grow.

      Also ;check temperature.

    • Maybe the grow light isn’t powerful enough? My wife was given two little seedlings that were struggling in a foggy area near the SF coast. In our sunny backyard, 20 miles south, they’re thriving. See below.

  • Shazeb

    So i have got the entire set up ready for the grow and my seeds have arrived , however once i germinate the seeds and start to plant them, i have no idea how to feed it. i have done research on NPK but i dont know how to determine the exact amount these plants need and i feel that i could use advice/guidance wherever possible please, any help?

      The first 2 weeks of a seedlings life they hav enuff to grow. After that use ferts follow directions on pkg but use about a 1/4-1/2 strength.

    • Ryan James

      step one. avoid general hydroponics nutrients.
      step two discuss a good nutriant (something with auto PH) like the sensi series.
      step three follow directions on the bottle 1/4 strength for 1 to two weeks after they are fully rooted (a period of time of 1 to 3 weeks depending on temperature and climate) then a week at half strength (or one feeding at half then the next at three quarters) then you should be in full veg. hit them with full strength the first week then then increase 10% past the package directions for mixing then 15 to 20 % for the last couple weeks of veg. first week of flower hit the full strength in hit the switch to 12/12 by week two of flower 110% feed levels the 115 to 120 % by week three … on the last week of feed if your plants are healthy they may be able to handle 130% feed … especially if you used overdrive with as a secondary rippener (also increasing light to the point that you need co2 may allow you to tweek your nutrients even higher

        There’s nothing wrong with General Hydroponics. Clearly you don’t know what the fuck you’re talking about.

        • big time

          Oo

        • ‘Bill Aires

          I would have to agree… the nature of virtually every nutrient package is the same… IF you do not know what the fuck you are doing.. you will end up with this stuff in your finished product and it will be nasty… Flush flush flush…..

          Gets old guys bad mouthing products when the product is not at fault…

        Hi Ryan. My name is Pamela. Are you still growing Blue Dream? I have 4 plants flowering (flushing now), and a new crop starting. I started using Cannazyme and Guano as well as extra Nitro. I could use a little help because my 4 flowering have the small buds on the bottom. What I would like to do is keep it growing. I’ve seen folks who have plants that are 3, 4 and 5 years old. Do you have plants you keep going? Also, I would like to buy Jack Herer seeds. Who do you recommend? Thank you in advance and I hope you are still checking this post. PPP

  • Shazeb

    what do i feed the plant? is there an exact NPK that i follow ? also, what ingredients should i look for in a fertiliser?

    • My best buddy’s HIGHLY experienced farmer father (since deceased) preferred simple Miracle Grow, used per package instructions. Working for me so far (two girls, 48 and 55″ tall, the shorter one much bushier, covered in buds and 2 weeks or so from harvest, SF Bay Area where we’ve had lots of heat, watering every 4-5 days, just started to flush).

      • Ryan James

        i mean sure you can grow weed with no nutrients in a nutrient rich medium, but what your describing is bush swag, miracle gro and watering every 4 to 5 days? and you have them up to 48 to 55 inches? i would like to know what the result was at harvest you should have them cured by now, are you able to get it tested in a lab where you are? i would be very suprised if it even had a medium level thc count (mid to high teens) that is a plant that i am right now feeding every 2 to 3 days and by next week it will be every 2 days (3 feeds and 1 flush a week) using 15 to 20 % increase in Nutrient levels per gallon. and it is Thriving !!
