Is it good to constantly heat up the soil ?

I mean, if you could make the soil dry out completely every 24 hours and than full water it.. would that be good ?

Will that cause monster roots ?

You can warm the soil a bit, but overdoing it will kill your plants. Cannabis can't tolerate a completely dry soil medium. It wilts easily until well into flowering. Keep soil temperatures between 60 and 75 degrees, and the soil, moist. A consistently damp(not wet) medium is best.

Our plants do need wet/dry cycles but.......
Yes, soil should be allowed to dry out, some, but not too dry. Too dry can easily occur in a container. I wouldn't push waiting to water. Pick a cycle and stick with it. 2,3, or four days. Whatever fits your conditions.

I start my plants during the winter and use warming pads to keep soil temps above 50 degrees.

Just aerate the water before watering. I never did that, but if u must do SOMETHING, haha. But yea, like veggie says, a little dry is good, totally dry = bad

Bad advise on drying the soil out, or even "a little dry" microbes need water to survive, lack of water will kill microbes and fungi and can destroy the structure of the soil (which can take a very ling time to heal), also causes erosion and dry spots in the container, which can result in bad drainage, that is all BAD. Of course too much water is a bad idea as well, but dry period in any container is a bad idea, especially if your a believer in keeping soil alive.

I can see a exception for straight coco grows, but not true organics.

As for heating, i would say add mulch, this will keep heat during the cool days and will also keep cool during the hot days, not to mention water saving, no need to keep it hot if your thinking that will speed up the composting, much more to it then that.

I'm talking about raising temps to as close as possible to the point the roots damage.. just below it, to maximize evaporation ..

I'm far more interested in keeping my dirt cool than warm, but just out of curiosity, how will you raise the temp of the dirt just to the point of almost damaging the roots but not past that point? Have you tried smart pots yet? They seem to evaporate off more than regular ones.

I do this to the water in my rain collection tote to prevent algae. Can't say I see any significant difference in the plants but not a controlled experiment. For my money, I would focus on soil structure as best way to improve aeration.

u just place heaters under the soil, touching it, and choose the highest temp that doesn't damage the roots, and have a sensor in the soil telling you what's the real temp .. so you can be sure you're not over heating .....

What is the highest temp that doesn't damage the roots?

I deleted my advice because I don't understand people who ask a question knowing full well they are going to do it anyway even if people till them not to. why waste our time asking questions??
I was joking in that comment .. ! :)

I made it cause u just said "dont do it" but no explanation.. so I didn't know why should I believe .. that's all bro

lol it doesn't matter how much.. irrelevant.. I'm just wondering, cause 'they' say full water it and wait till it's fully dried....... so I thought - why wait 4-6 days or so.. and not do it every 24hours , maybe it's better.. that's all.

BTW from what I understand, smart pots are good only because they allow water but no soil out of the pot from the sides and bottom...... it's sort of a passive way to do what I'm talking about, and actually work together with what I'm saying .
