44° F Runoff Temp! Rootzone Temperature

[MCPotential]

Soil grower here...

Regardless of my growing environment here's something interesting:

I'm watering with 69° - 71° and the run off is 44° which is way to cold and I'm assuming that is affecting my plants tremendously, I did have a water bed heating mat under the plants but it burnt out on me so may need to get an electric blanket.

What impact does a RootZone of 42° have?

Thoughts?

Damn that's crazy. 70 going in and 44 coming out?! So that would mean your roots are growing in a block of ice?

U got pics of your plants tho?

What is the ambient temp. of the room you are growing in? I grow in a room that is 60-61 deg. My res. temp. drops to ambient room temp. when lights are off, climbs to about 63-64 deg. when led's are on.

Ha no block of ice, I had a nutrient lock out a few weeks ago and had to flush and a couple plants just never drank/dried out....I think since my RootZone at the bottom of my medium is pretty cold, im gonna find a thermometer here and see what it is from top to bottom.

Ambient is 85 lights on
Roughly 68-64 off

I could flush them again till temp gets up in my soil and then keep them warm somehow....here's some pics

Lots of clawing and a few yellow, theyre stressed for sure

U would think I'm over watering but they ain't drinking so it's maybe once a week for some and theres 2 that I water twice a week maybe

Did you just repot with soil that had been stored outside in freezing temps? That is the only reason I could think of that would cause runoff temps like that. If that is the case, soil and runoff should adjust themselves.

I will test run off water again....I was thinking because the ground under my tent is a mere 40degrees thus keeping the mediums extremely chilled....but I put cedar shaving under my grow box....those were transplant 3 weeks ago

Maybe elevate your pots off the ground with upside down saucers or something to allow an air gap,. Is there cement under your tent? I had the same issue and elevating them helped a lot.

I don't want to jump to conclusions yet but they almost instantly look better! Right now in Portland Oregon it's 25 degrees and cold at.....but.....I have had a heated blanket on them.

Besides the 1 plant, the rest look almost to be throw aways....but here's the pics

Go to home depot and get a piece of foam board to put under your tray ti isolate it from the cold concrete.
