# What limits can I set?

You can set limits for a wide range of environmental factors to keep your grow conditions optimal. These include:

* Temperature
* Humidity
* CO₂
* VPD (Vapour Pressure Deficit)
* Leaf VPD
* Leaf temperature
* Leaf temperature offset
* ePPFD (Extended Photosynthetic Photon Flux Density)
* Daily Light Integral (DLI)
* Dew point gap
* Substrate temperature
* Substrate moisture
* EC (Electrical Conductivity)

By setting these limits, you can create a controlled, efficient grow environment tailored to your plants' needs.
