🌺 Environmental Control Guidance
Get crop-specific temperature, humidity, ventilation, and light level targets for your greenhouse — tailored to your production phase, structure, and current equipment. Includes DIF guidance and troubleshooting for common environmental problems.
⚠️ Important: Environmental control guidance provided by Sage is based on general crop parameters and typical production practices. Actual temperature, humidity, and light targets will vary based on your specific variety, structure, equipment, and local climate. Always validate recommendations against your own crop performance and consult local extension resources or a certified crop advisor when in doubt.

📅 Use the Production Week Reference above to find your current week number.
Step 3 — Lighting, DIF & Current Issues
None — natural light only
HPS lighting
LED grow lights
Fluorescent / T5
Photoperiod lighting (day extension / night interruption)
Low — under 1,000 foot-candles / DLI below 10
Medium — 1,000-3,000 foot-candles / DLI 10-20
High — over 3,000 foot-candles / DLI above 20
I measure in DLI — I will enter below
Yes — using positive DIF (day warmer than night)
Yes — using negative DIF for height control
Not currently using DIF
Not sure what DIF is
Excessive stretch / elongation
Tip burn or edge necrosis
Bolting prematurely
Slow crop — behind schedule
High disease pressure (Botrytis, Powdery mildew)
Heat stress / bleaching
Cold damage / chilling injury
Condensation / dripping on plants
No current issues
✨ The more detail you provide, the more targeted the environmental control recommendations will be.
