Let's Get Growing!
The lights are in position. The growing unit, hydroponic system or planting containers are in place. Fans are installed in the space as appropriate to provide air circulation. A CO2-enrichment or ventilation system is set up to provide a continuous source of CO2 during the lit period.
Temperature and humidity are controlled with sensors and automatic systems using air coolers, air conditioners or a ventilation system using filtered outdoor air.
You should also be prepared to monitor the nutrient mix by measuring either the parts per million (ppm) of nutrients, the electrical conductivity (EC) of the solution, or the total dissolved solids (TDS). You have a pH meter or test kit to measure pH. A surface temperature meter and a light meter are also useful.
