Gardin Product Release - ALPHA Index - how good is your climate?
Gardin's new ALPHA Index helps growers measure how climate and irrigation decisions affect plant performance, removing the influence of light to reveal real-time climate strengths and weaknesses.
We’re excited to announce one of our most anticipated features - ALPHA Index!
What is ALPHA Index?
The ALPHA Index removes the influence of light from EFFICIENCY, leaving only variation caused by changes in climate and irrigation. We do this by taking a moving five-day baseline of your plants to estimate what average performance would look like under the current lighting conditions, then subtracting that from the actual observed performance.
Gardin Fig 1: A positive ALPHA indicates that your climate is exceeding baseline plant performance. A negative ALPHA, on the other hand, flags periods where climate conditions may be worse than normal. The index fluctuates throughout the day and can be monitored in real time to improve the climate strategy.
Inspired by the concept of excess return, ALPHA highlights when your climate control is driving performance beyond your typical strategy. A positive ALPHA indicates that your climate is exceeding baseline plant performance. A negative ALPHA, on the other hand, flags periods where climate conditions may be worse than normal.
This unlocks a new level of plant-driven growing by allowing you to assess the strengths and weaknesses of your climate strategy, all at five-minute resolution. With ALPHA, you can begin to answer practical questions such as:
- What is the most effective way to use misting?
- Is the greenhouse heating up fast enough in the morning?
- What is the impact of not supplying excess CO2 in the greenhouse?
- Where is the climate weakest across compartments?
- How can irrigation timing be improved?
ALPHA Index is now available on all subscription tiers, we hope you like it and can’t wait to hear what our customers learn from it!
