Do plants need a colder night temp?

50 degree nights

I am thinking about this and i think i know whats different. The cold basement under artificial lights with relatively cool (70’s) growing conditions the cold floor causes the same problem as overwatering consistently.

outside in the sun can still have good dry cycle so the roots are colder but not so wet and cold.

Ok so here is my take... root temps and plant temps are far more important than air temps and they are very different... plants sustain low air temls when the root temos are reasonable.

Imo the root twmls have much more influence on the plant than air temps... like was said indoor in small pots it can be an issue outdoor not so much because ground temps are very stable.

This is where again an IR temp gun... they are dirt cheap can really help you understand teml wise where the plants at and how well they are fairing in your environment.

What about colder temps in the last 2 weeks? I read that some people are pointing an air-conditioner at their plant for the last 2 weeks. Is that just bro science?

i said the same but @mancorn showed healthy plants in small containers outside with 50 degree night temps. So i think cold and wet is the problem. Not just cold as dryish cold roots will heat up quickly at lights on so to speak.

that is to bring out color. Purple. Which is actually the same thing. Cold roots. Poor phosphorous uptake. Purple color results.

Govee minister and app allows me to keep an eye on the temp and humidity gap from lights on to lights off.

i got one of those and love it

okay, it doesn't affect potency?
By the way, i started reading your grow journal last night and was blown away. So fun to watch your grow journey

No but high temps can affect terps and degradation.

thank you very much. :-). And its high temps under lamps that can hurt potency, flavor and smell from burning terps and heat stressing in general.

oops i just posted this right after in my response.

Yeah I’m always sweating (ha ha) the warm days and never really think too much about the cool night. Another May picture where I had to put the pots in protectors as the little ladies weren’t in the ground and frying due to an early heat wave.

Edit: I no longer recommend the Daytime, but rather Drake’s Kick Back for day drinking

I STOOD tent on top of plastic shipping pallets with a2 inch peace of blue board helps a lot with cold concrete/cold root problem i will try for a soil temp latter runs at77-79degrees 47%-50%rh

I didnt see it coming. It was my first grow in my new (old) house. The basement got down to 45 in the back end with the tents. Pallets and insulation board didnt help.

i put a oil heater in my tent.helped even out temps and RH

tried that too. But i was likely too late with soggy roots by then. I was a much newer grower and did not know what was happening at the time.
