1. Light Spectrum — Wavelengths & Ratios / 光谱 — 波长与比例

Cannabis uses photosynthetically active radiation (PAR) from 400–700 nm. Two key photoreceptor families drive growth:
大麻利用400–700 nm的光合有效辐射（PAR）。两大光受体家族驱动生长：

Chlorophyll a/b
叶绿素a/b — absorption peaks at ~430 nm (blue) and ~662 nm (red)
吸收峰在~430nm（蓝光）和~662nm（红光）
Cryptochromes & Phytochromes
隐花色素和光受体 — control photomorphogenesis: stretch, branching, flowering timing
控制光形态健成：伸长、分枝、开花时机

2. PPFD Targets by Growth Stage / 各阶段PPFD目标

PPFD = Photosynthetic Photon Flux Density (μmol/m²/s). Canopy-level averages measured at the top of the tallest cola. A PPFD = 光合光子通量密度（μmol/m²/s）。冠层平均值在最高花蕾顶部测量。PAR meter (Apogee MQ-500, Li-190R) is essential.

Always measure with a PAR meter.始终使用PAR计测量。 Wall reflectivity (95% white/mylar raises edge PPFD 20–30%) and canopy density affect these estimates.

3. DLI (Daily Light Integral) Targets / DLI目标

DLI = PPFD × light hours × 3,600 ÷ 1,000,000 (mol/m²/day).
DLI = PPFD ×光照小时 × 3,600 ÷ 1,000,000（mol/m²/天）。

Growth Stage 阶段	DLI Target（mol/m²/d）	Photoperiod 光周期	Equivalent PPFD 等效PPFD
Seedling幼苗 / Clone幼苗 / 克隆	6–10	18/6	93–154 μmol/m²/s93–154 μmol/m²/s93–154 μmol/m²/s93–154 μmol/m²/s

Critical DLI Rule / 关键DLI规则: Saturation point (ambient CO₂): ~40 mol/m²/day. Saturation point (1,200 ppm CO₂): ~55–60 mol/m²/day. Beyond these → no yield increase, only stress risk.

5. VPD (Vapor Pressure Deficit) 蒸气压差

VPD measures the drying power of the air — directly controls transpiration rate and nutrient uptake.
VPD衡量空气的干燥能力——直接控制蒸腾速率和养分吸收。

6. CO₂ Enrichment / CO₂补充

Cannabis is a C3 plant. At elevated CO₂ (1,200–1,500 ppm), the plant can tolerate higher PPFD, increase photosynthetic rate by 30–50%, and shorten flower time by 7–14 days.

Condition 条件	CO₂ Level (ppm)	When to Use 使用时机
Ambient (no supplement)环境（不补充）	400–450400–450	Standard grows, PPFD ≤ 600 μmol/m²/s标准种植，PPFD ≤ 600 μmol/m²/s
Low supplement低量补充	800–1,000800–1,000	PPFD 600–900 μmol/m²/s, better yieldPPFD 600–900 μmol/m²/s，更高产量
High supplement (commercial)高量补充（商业级）	1,200–1,5001,200–1,500	PPFD 900–1,100 μmol/m²/s1,100 μmol/m²/s, sealed room requiredPPFD 900–1,100 μmol/m²/s1,100 μmol/m²/s，需密封房间
Maximum最大值	1,5001,500	Diminishing returns above 1,500; toxic >2,000 ppm超过1,500后收益递减；超过2,000 ppm有毒

CO₂ Schedule / CO₂时间表:

Lights ON only (CO₂ uptake depends on photosynthesis)
Turn off CO₂ 15–30 min before lights OFF
Only use from mid-veg through mid-flower. Stop in last 2–3 weeks.
Sealed room required for high CO₂ — exhaust fans purge CO₂

Eclipse 328 + CO₂ Synergy: Without CO₂, dim to ~60–70% to avoid >900 μmol/m²/s. With CO₂ at 1,200 ppm, run at 90–100%, maximizing every diode.

将4个登山扣连接到角落安装点。连接可调节绳索吊架（随附）。
Set Height / 设定高度: For seedlings, start at 30–36" above canopy. Adjust rope hangers to desired height using the ratchet mechanism.
幼苗阶段从冠层上方30–36英寸开始。使用棘轮机构调节绳索吊架至所需高度。
Connect Power / 连接电源: Plug the external LED driver into a 120V/240V outlet. Connect the driver output cable to the panel's DC input port.
将外置LED驱动电源插入120V/240V插座。将驱动输出线连接到面板的DC输入端口。

下载K99应用程序。开灯后按照应用内配对说明操作（BLE 5.2自动发现）。
Initial Dimming / 初始调光: Set dimmer to 20% for seedlings. Use the app or onboard dial to adjust intensity.

Verify PPFD / 验证PPFD: Use a PAR meter (Apogee MQ-500 recommended) to measure canopy-level PPFD. Adjust height/dimmer accordingly.
使用PAR计（推荐Apogee MQ-500）测量冠层PPFD。相应调整高度/调光。

Optimization Tips 优化技巧

Light Distribution 光分布优化

Reflective walls / 反光墙面: Use 95%+ reflective material (white paint, Mylar, Orca Film). This recovers 20–30% edge PPFD.
使用95%+反射率材料（白色涂料、Mylar、Orca Film）。可回收20–30%边缘PPFD。
SCROG net / 绿幕网: Create a flat, even canopy so all colas receive uniform PPFD.
创建平坦均匀的冠层，使所有花尖接收均匀PPFD。
Rotate pots weekly / 每周旋转花盆: Compensate for any hot/cold spots in the room.
补偿房间内任何热/冷点的影响。

Smart Control Tips 智能控制技巧

Sunrise/Sunset Ramp / 日出日落渐变: Program 15-min ramp-up/down via WiFi app. Reduces plant shock, improves morning CO₂ uptake.
通过WiFi应用设置15分钟渐亮/渐暗。减少植物冲击，改善早晨CO₂吸收。
EOD-FR Protocol / 日末远红光协议: In the last 15 min before lights-off, boost deep red to 100%. This mimics far-red sunset and can accelerate flowering by 3–7 days.
关灯前最后15分钟将深红光调至100%。模拟远红光日落，可加速开花3–7天。
Cloud Simulation / 云层模拟: Set a 5–10% intensity dip at midday. Some growers report this triggers mild stress response, increasing terpene production.
在正午设置5–10%强度下降。部分种植者报告这触发轻度应激反应，增加萜烯产量。
Late-Flower Fade / 晚期开花渐减: Reduce intensity降低强度 10–15% per week in the last 2–3 weeks. Signals plant to allocate energy to resin and maturation.
最后2–3周每周降低强度10–15%。向植物发出信号，将能量分配给树脂和成熟。

Environmental Synergy 环境协同

CO₂ + High PPFD / CO₂ + 高光强: Only push PPFD above 850 μmol/m²/s when CO₂ is ≥1,200 ppm. Without CO₂, cap at 800.
仅在CO₂ ≥1,200 ppm时将PPFD推至850 μmol/m²/s以上。无CO₂时上限为800。
LED Temperature Compensation / LED温度补偿: LED produces less radiant heat than HPS. Raise ambient temp 2–5°F to achieve optimal leaf temperature (77–82°F).
LED产生的辐射热少于HPS。将环境温度提高2–5°F以达到最佳叶温（77–82°F）。
VPD-First Approach / VPD优先策略: Always calculate VPD using leaf temperature (IR gun), not air temperature. Under LED, leaf is 1–4°F cooler than ambient.
始终使用叶温（红外温度枪）计算VPD，而非气温。LED下叶温比环境低1–4°F。

Troubleshooting 故障排除

Leaf Curling (Taco) 叶片卷曲

Cause / 原因: PPFD too high and/or VPD too high (air too dry)VPD过高（空气太干）. PPFD过高和/或VPD过高（空气太干）。

超过这些阈值后，光呼吸增加，净光合速率趋于平稳。更高的PPFD如果没有相应的CO₂、营养和VPD管理，只会浪费能源并带来损伤风险。

LED-Specific VPD Correction / LED专用VPD修正

Under full-spectrum LED (low IR/radiant heat), leaf temperature runs 1–4°F cooler than ambient air. This creates a steeper vapor gradient at the leaf surface.
在全光谱LED（低红外辐射热）下，叶温比环境气温低1–4°F。这在叶片表面产生更陡的水蒸气梯度。

Factor 因素	HPS (Traditional)	LED (Eclipse 328)
Leaf temp vs ambient / 叶温vs环境	+5–8°F above ambient比环境高+5–8°F	-1–4°F below ambient比环境低-1–4°F
VPD correction formula / VPD修正公式	Standard VPD charts标准VPD图表	`VPD_actual = VPD_ambient × 1.1–1.15VPD实际 = VPD环境 × 1.1–1.15`
Practical adjustment 实际调整	—	Run 5–10% higher RH than chart suggests比图表建议的RH高5–10%
Ambient temp adjustment 环境温度调整	—	Raise ambient 2–5°F vs HPS settings比HPS设置提高环境温度2–5°F

Rule of thumb / 经验法则: Maintain leaf temperature at 77–82°F (25–28°C) during lights-on for flower. Measure with IR thermometer.
开灯期间保持叶温在77–82°F（25–28°C）（开花期）。使用红外温度计测量。

Wavelength 波长	730–740 nm far-red
Timing 时间	Last 10–15 minutes before lights-off / 关灯前最后10–15分钟
Intensity 强度	15–20% of total PPF, or deep red channel at 100%

2025 pH Best Practice — pH Drift / 2025 pH最佳实践 — pH漂移: Rather than locking pH at a single value, allow it to drift within the optimal range (5.5→6.2 for coco/hydro, 6.0→7.0 for soil). This ensures all nutrients are available across their respective absorption windows.
不要将pH锁定在单一值，而是让其在最佳范围内漂移。这确保所有营养元素在各自的吸收窗口内均可获得。

2025 Update: Under full-spectrum LED (low IR), leaf temp runs 1–4°F cooler than ambient. LED growers must raise ambient temps 2–5°F to achieve the same leaf temperature as HPS.
在全光谱LED（低IR）下，叶温比环境低1–4°F。LED种植者必须将环境温度提高2–5°F。

Humidity (RH) Targets by Stage 各阶段湿度目标

Growth Stage 阶段	Target RH (%)	Notes 备注
Seedling幼苗 / Clone幼苗 / 克隆	70–80	High humidity reduces transpiration stress on underdeveloped roots

VPD Management for LED (2025 Best Practice) / LED VPD管理

Leaf-to-air differential: Under LED, leaf temp is 1–4°F cooler than ambient. Use actual leaf temperature (IR gun) to calculate VPD.
Formula for LED growers: VPD_actual = VPD_ambient × 1.1–1.15VPD实际 = VPD环境 × 1.1–1.15 — run 5–10% higher RH than charts suggest.
Dew point awareness: VPD <0.4 kPa → dew forms on leaves → powdery mildew. VPD >1.8 kPa → stomata close → growth stops.
Airflow: 1–2 m/s at canopy level (gentle oscillation) is optimal.

Dawn/dusk ramping: Eclipse 328 WiFi can do 15-min intensity ramps. Strongly recommended.
Consistency: Lights on/off within ±1 minute daily. Circadian drift stresses plants.
Light leak protocol: Anything above 0.01 μmol/m²/s can disrupt flowering.

Stop CO₂	End of week 5–6 of flower (2–3 weeks before harvest)
CO₂ ON schedule	Lights ON only. Start 15 min after lights on, stop 15–30 min before lights off.
