Coco Run-off Temp

[vonwolfen]

I was checking run-off(ph/ec) in 6 off my plants(6th week of flower), and noticed that the run-off was noticably coolder(15.5-17.8c) then the fluid going in(21.5-22c). Has anyone else checked the temps of their run-off? I suspect that the coco, and the roots must be even colder then the 15-17c run-off since the fluid going in is at 22c. This seems bad, really bad. What can be done about it? With-in reason..I cant put a heater into every grow-pot(smart pots 3 gallon).

I've never checked temps of run-off, but I have checked temps of root zone. Cold growing indoors was what I was struggling with for a while, and you're right, it's no way to grow. My solution? Electric Blanket Sandwich. Use thick contractor bags, be careful not to pinch wires, protect the connection point because it's not waterproof. Lay some corrugated plastic over the top and you're off and running again.

How cold is your room to allow your pots to get that chill? Are they sitting on cold floors or something?

And if you're in week 6 of an 8 week stain, I wouldn't worry about it too much.
