Refurbished soil HVAC system, and increased airflow.
To maximize your yield, always aim for 40 moles, or 40,000,000 μmol, per day. Here is how much PPFD is needed per second for each phase of cannabis growth to achieve the DLI of 40 moles of light per day.
I picked up a Quantum PAR Meter, very happy!😁 PAR Meter will show me how much useful radiation between 4-700nm the plant is getting from any given direction.
Seedling phase (18hr cycle): 200–300 μmol m-2 s-1
Vegetative phase (18hr cycle): 617 μmol m-2 s-1
Flowering phase (12hr cycle): 925 μmol m-2 s-1, (1500 μmol m-2 s-1 @1500ppm co2) (ballpark). Anything above 2000 PPM is harmful to both the grower and the crops.
The tent is currently reaching 3-400umol ms 1s at soil level (42" inches from light) and 1100umol-1300umol @ 25" Inches.
