Watered lightly with:
BioBizz Root Juice β 2ml/L
pH: 5.8
EC: 0.4
Results: 10/10 sprouted with aggressive root growth. Plants stood tall with zero stretch. Early signs of strong phenotypic uniformity.
Lighting: 600W HPS turned to full 600W, 24" above canopy
Nutrient Mix:
Root Juice: 2ml/L
Bio-Grow: 1ml/L
Acti-Vera: 1ml/L
CalMag: 0.3ml/L
pH 5.9 | EC: 0.6
Progress:
Transplanted to 3L pots mid-week.
Side branching had already started.
Plants squat, lush, and wide β early signs of massive internodal development.
Pot Up: Into 11L final fabric pots
Environment: 27Β°C | RH 60%
Training: Began topping after 4th node
Feeding:
Bio-Grow: 2ml/L
Fish Mix: 1ml/L
Acti-Vera: 1ml/L
CalMag: 0.5ml/L
pH: 5.9 | EC: 0.9
Observation:
Banana Mac is a medium-stretch strain, so topping early and training wide is key. Side branches already thickening. Plants have rich, oily leaves.
Lighting: 18/6
Training: Full LST, branches spread and tied down
Feeding:
Bio-Grow: 2.5ml/L
Fish Mix: 1ml/L
Acti-Vera: 1ml/L
CalMag: 0.5ml/L
pH 6.0 | EC: 1.1
Result:
All 10 plants showing vigorous lateral growth
Canopy well structured, preparing for flower
Root zone fully colonized β pot weight drops fast between feeds
Lighting: Switched to 12/12, HPS kept at 20"
Environment: 28Β°C | RH 55%
Feeding:
Bio-Grow: 1ml/L
Bio-Bloom: 1ml/L
Top-Max: 1ml/L
CalMag: 0.4ml/L
EC: 1.3 | pH 5.9
Observation:
Pre-flower pistils on Day 4 post-flip. Stretch initiated immediately. Dense leaf canopy responded well to defoliation at flip.
Feeding:
Bio-Bloom: 2ml/L
Top-Max: 2ml/L
Bio-Heaven: 1ml/L
Dense Max Professional: 40ml/L (Day 5 only)
pH: 6.0 | EC: 1.6
Effect of Dense Max (40ml/L):
Within 48 hours, bud sites visibly swelled.
Calyx-to-leaf ratio began to shift in favour of denser flower stacks.
Leaves perked with βprayer handsβ posture β no burn, no clawing.
Dense Max Applied TWICE: Day 2 and Day 5
Feeding:
Same as Week 6
Dense Max: 40ml/L x2
EC: 1.7
Results:
Buds look 1β2 weeks ahead compared to previous Banana Mac grows.
Trichomes are already forming.
Floral aroma begins faintly β banana rind, slightly doughy.
Final Week of Dense Max
Applied 40ml/L on Day 2 and Day 5
Feeding:
Bio-Bloom: 2.5ml/L
Top-Max: 2ml/L
Bio-Heaven: 2ml/L
EC: 1.8
Results:
Buds dense and sticky β visibly chunkier than normal BioBizz-only runs.
All 10 plants now forming thick colas, minimal spacing between internodes.
Banana terps now strong β like overripe fruit mixed with hash.
Feeding:
Bio-Bloom: 3ml/L
Top-Max: 2ml/L
Bio-Heaven: 2ml/L
CalMag: 0.3ml/L
EC: 1.8
Notes:
Dense Max results holding beautifully β firm, rock-like buds on every top.
All Dense Max applications completed β residual effects noticeable.
Pistils 40% brown on some colas already.
Feeding tapered slightly:
Bio-Bloom: 2.5ml/L
Top-Max: 1.5ml/L
EC: 1.6 β 1.5
Defoliated again to expose lower bud sites.
Results:
Buds have zero fluff β dense to the stem, weighty.
Trichome heads fully swollen, 10β15% amber forming.
Aroma now intense β fermented fruit, sharp gassy edge.
Feeding: Plain RO water with pH adjusted to 6.0
Flushed every 2 days
Final runoff EC: 0.2
Observation:
Leaves fading beautifully into yellow/purple tones.
Buds continue to harden β zero shrinkage post-flush.
Chop scheduled for Day 89.
Hung whole for slow dry at 18.5Β°C | RH 50%
Trimmed on Day 97
Cured in jars with Boveda 62% for 4+ weeks
Dry Yield per Plant: 122g (4.3 oz average)
Total Yield: 1,220g (~43.2 oz)
Bud Quality:
Structure: Solid colas, calyx-loaded
Aroma: Sweet banana fuel
Effect: Relaxing but surprisingly euphoric
Bag Appeal: 9.5/10
Grower Verdict:
βThe 40ml/L rate of Dense Max Professional delivered explosive density without sacrificing terpene quality. Compared to earlier runs of Banana Mac without Dense Max, this grow produced 30β40% heavier and tighter buds. Zero larf. Just wall-to-wall chunky frost.β
Dense Max Professional is ideal for runs with BioBizz where organic density can be lacking.
Coco + HPS + Organic combo worked better than expected.
Defoliate mid-flower for best airflow and light penetration.
Consider reducing HPS distance slightly mid-flower β some mild taco-ing at 24β under 600W.
