Horticulture reference
Cannabis grow guides
Documented protocols covering every stage of indoor cannabis cultivation — from the day a seedling cracks through to a cured jar. Photoperiod and autoflowering lines treated as equally legitimate. Numbers reflect what's published in horticulture literature and hobby-scale grower reports.

Purpose
Educational reference. Not legal, medical, or growing advice.
Vegetative stage
What the vegetative stage is, the light schedules described in horticulture references, documented feeding ranges, low-stress training, and the cues that mark the end of the phase.
Read the reference
Flowering stage
How the flowering response is triggered in photoperiod plants, the stretch phase, week-by-week bud development, documented calcium-magnesium needs, and the late-flower flush debate.
Read the reference
Harvest
Documented trichome staging against the published flowering time, morning-versus-evening chop, and wet trim versus dry trim as described in horticulture literature.
Read the reference
Drying and curing
The 15 °C / 60% RH target, the eight-to-fourteen-day dry window, jar curing protocol, burping cadence, and how failed jars are described in grower reports.

Environment & equipment
What the plant lives in — feeding regime, light spectrum, tent setup, and the mistakes documented in published grower reports.
04
Nutrients
Documented NPK ratios by stage, published calmag dosing, EC targets in soil and coco, mixing order, the organic-versus-synthetic argument, and how the most-cited deficiencies appear.
Read the reference
Lighting
LED versus HPS versus CMH, documented PPFD targets per stage, DLI math, hanging distances, light burn, and the photoperiod-versus-auto schedule split.
Read the reference
Tent setup
Tent sizing for one to four plants, exhaust CFM math, carbon filter pairing, intake placement, humidity and VPD targets per stage, and what controllers automate.
Read the reference
Common beginner mistakes
The most-cited beginner errors in published grower reports — overwatering, overfeeding, pH neglect, calendar-based harvest decisions, the aggressive flush, light too close, and ignored VPD.
