  • Cooler nights in late flower can enhance purple colors

Humidity:

  • Vegetative: 50-60%

  • Early Flower: 45-55%

  • Late Flower: 35-45%

Lighting:

  • Indoor: 600-1000W HPS or equivalent LED

  • Minimum PPFD: 600 μmol/m²/s in flower

  • Light schedule: 18/6 veg, 12/12 flower

Growth Characteristics

Understanding Blue Dream's growth pattern helps you plan:

Vegetative Stage:

  • Vigorous vegetative growth

  • Stretchy Sativa-influenced structure

  • Strong main stem development

  • Responds well to training

  • 4-6 weeks veg recommended for indoor

Stretch and Transition:

  • Expect 50-100% height increase during stretch

  • Stretch lasts 2-3 weeks after flip

  • Plan ceiling height accordingly

  • Training essential for indoor grows

Flowering Stage:

  • Long, dense colas develop

  • Abundant trichome production

  • Sweet aroma intensifies weekly

  • Calyxes swell in final weeks

Training Techniques

Blue Dream's structure makes it ideal for training:

Topping (Recommended):

  • Top at 5-6 nodes

  • Creates multiple main colas

  • Controls height

  • Increases yield potential

Low-Stress Training (LST):

  • Bend and tie branches

  • Opens canopy for light penetration

  • Blue Dream responds excellently

  • Start early in veg

Screen of Green (SCROG):

  • Ideal for Blue Dream's stretch

  • Maximizes light exposure

  • Controls height effectively

  • Excellent yield per square foot

Super Cropping:

  • Blue Dream handles stress well

  • Bend stems to create knuckles

  • Strengthens branches

  • Improves nutrient flow

Feeding Blue Dream

Blue Dream is a moderate to heavy feeder:

Vegetative Feeding:

  • Higher nitrogen (N) for vigorous growth

  • Standard veg nutrients work well

  • Don't overfeed - start at 50% strength

  • Watch for nitrogen burn (dark, clawing leaves)

Transition Week:

  • Reduce nitrogen

  • Begin increasing phosphorus and potassium

  • Add bloom nutrients

Flowering Feeding:

  • Increase P and K for bud development

  • Reduce N to prevent larfy buds

  • Cal-Mag often beneficial

  • Follow nutrient schedule or adjust to plant response

Flush:

  • 7-14 day flush before harvest

  • Plain pH'd water only

  • Improves final flavor

  • Leaves will yellow naturally

Common Growing Issues

Stretching Too Much:

  • Common with Blue Dream's Sativa genetics

  • Solutions: Top early, use SCROG, keep lights close

  • Increase light intensity if possible

Nutrient Sensitivity:

  • Some phenotypes are picky

  • Start feeds at lower concentration

  • Increase gradually

  • Watch leaf tips for burn

Foxtailing:

  • Can occur in late flower

  • Often genetic trait, not always a problem

  • Heat or light stress can worsen it

  • Monitor trichomes for harvest timing

Mold/Mildew Risk:

  • Dense colas can trap moisture

  • Ensure good airflow

  • Keep humidity low in flower

  • Inspect buds regularly

Phenotype Variations

Blue Dream can vary depending on the phenotype:

"Blueberry-Dominant" Phenos:

  • More Indica structure

  • Sweeter berry flavor

  • More relaxing effects

  • Typically shorter plants

  • Faster flowering

"Haze-Dominant" Phenos:

  • Taller, stretchier growth

  • More cerebral effects

  • Longer flowering time

  • Pine and citrus forward

  • Higher yield potential

Finding Your Favorite:

  • Grow multiple seeds

  • Clone the best performer

  • Each pheno offers something unique

  • Document differences for future grows

Harvest and Yield

Harvest Timing

Optimal Window:

  • 9-10 weeks of flowering

  • Some phenos extend to 11 weeks

  • Watch trichomes, not calendar

Trichome Guide:

  • Harvest at 10-20% amber for balanced effects

  • More amber = more sedating

  • Mostly cloudy = peak THC, energetic effects

Expected Yields

Indoor:

  • 400-600g/m² typical

  • Up to 700g/m² with advanced techniques

  • SCROG particularly effective

Outdoor:

  • 500-700g per plant

  • Can exceed 1000g in ideal conditions

  • Harvest mid-October (Northern Hemisphere)

Drying and Curing

Drying:

  • 60°F, 60% humidity ideal

  • 7-14 days until stems snap

  • Don't rush - quality depends on proper drying

Curing:

  • Mason jars, 62% humidity

  • Burp daily first week

  • Cure minimum 2 weeks, 4+ weeks ideal

  • Blue Dream's flavor develops beautifully with cure
