I've asked this before, but didn't get a solid answer.... so as we do we ask again.

 

I have read that the temperature of a hot pepper plant (above the roots) can tolerate high temperature (90degF-100degF....100+) consistently, but the root system has to be kept cooler in order to thrive. This condition of course is based on a quality root system.....  Do I have to keep the roots cool in order to have a quality plant when the ambient temperatures are above 90degF ?

 

I'm working on a (tent system) where I totally disregard the temperature inside of the tent. I have the grow medium ( and roots) underneath  the grow tent, where the plant can grow up and into the bottom of the tent. I can keep the grow medium (under the tent) at good room temp, while allowing the plant that grows up and into tent get to a relatively high temp without affecting the root temps. I have to work out the details of the watering.

 

 So my basic question is..... should I spend so much time and effort controlling the soil temperature ?

 

Happy Growing,

 

Jeff

Hey!

 

I'm not sure about the temps the roots can tolerate but have you tried burying a thermometer at a few different depths to see what kind of temps you'll be dealing with under the soil? I have trouble envisioning the heat penetrating more than an inch or two down especially when you plop a tent on top that blocks out any direct light or heat from hitting the top of the soil.

 

Sorry wish I could give you better input on the root temp question.

 

Cheers

There was a member (can't remember) that was in a dry 140 degree sun. He covered a room with thick plastic to cut the sun. Air temp 140f. He was in containers so the roots had to be warm. He had a continuous drip system set up. Plants looked great! Waters the key.
