WINTER WARM UP

As the temperatures drop, your plants will need extra warmth. Cold damage is not always easy to spot, and many growers may misdiagnose it as a disease or deficiency. The most common cause is temperatures falling overnight, inflicting mild cold injuries on sensitive plants.

What happens

As the lights in your room go off the temperature in you grow room can plummet, this is bad on many levels.

1  The heat in you room drops significantly and quickly this shocks your plants and can stop them feeding losing yield.  Temperature of your grow room over night or when lights are off is also crucial for when lights go back on, humidity can increase due to the quick increase of temperatures and your plants don’t start feeding straight away as the root ball is so cold this loses you time and yield. 

REMEMBER YOU DON’T WANT MORE THAN A  6°  TEMPERATURE SWING BETWEEN DAYTIME AND NIGHTTIME CYCLES

 

2  humidity in your grow room will also shoot up.  If you are in flower when this happens it could give you problems with Botrytis also known as bud rot causing you to lose yield.   

 Plant deficiencies can be mistaken for cold temps, this is a night mare as you could end up spending money on products that you don’t need trying to fix a problem that could be fixed by buying the correct equipment
