Ice to cool marijuana roots


A question from a fellow grower:

My plants are experiencing between 80 -90 degrees at tmes I got some o2 genrator for the cooling of the plants and seems like it working… I was just wondering if my plants gets to hot would Ice work on the soil to help cool the plants down?


Cooling of the root zone is generally an issue for hydroponic growers.

Perhaps you can freeze some 2 liter coke bottles, and place them behind your oscillating fan. This will draw cool air for a while. Replace as necessary. Monitor your Relative Humidity. In flower; You want to keep humidity at around 40%
