Not too hot and not too cold; many of the plants we grow are just like us and prefer similar temperatures — between 65 to 85 degrees Fahrenheit.
Also, like us, they hate extreme temperatures changes. Plants will temporarily stress out when adjusting to them.
Controlling temperatures is one of the single most important aspects of growing. If you fail to do so, you will wreck your plants nutrient uptake and weaken them to diseases before they eventually die. How about I show you how to avoid this?
Let's take a look at some common grow tent heat problems, and how to remove this heat from your grow tent or grow room.
Never Grow Without A Thermometer / Hygrometer
A thermometer and hygrometer are essential to every indoor garden. Locking your plants into their preferred temperature and humidity ranges is crucial for nutrient uptake.
If your vapor pressure deficit (VPD) is off (air temp + leaf temp + relative humidity), then your plants will either drink and uptake too much or not enough nutrients. It’s common to see calcium deficiencies because transpiration is largely affected.
If this happens, you can use a cal-mag supplement. But you will need to address the root cause eventually as well.
