Do Roots Really Grow In The Dark?

[kushykush11]

I just figure plants naturally get a dark period and that they would do better in dark so this makes sense

 

[SmokyJelly]

So, will LED lights help the root growing?

Good article, thank you for sharing. I used to be confused about this, whether the roots need light or not, now, I've got a little sence of it.

What happens on top during photosynthesis happens down below during dark period.

in photoperiod plants it is the shock in the reduction in lights on time that starts flowering hence going from 18 to 12 makes the plant think its coming to the end of the growing season (Autumn/fall) and therefor produces flowers to reproduce . its the same for most plants, unless you are using auto flower which I have no experience. I prefer to control the cycle.

i can tell you that my plants grow 3" in 30 hrs of dark cycle when Im flipping to 12/12....i dont look at the roots but that should indicate something.

Absolutely - I see a major surge in that 36 hours darkness at start of flip and i am convinced that a lot of growth goes on in the dark

Myself I use 6 on 2 off cycle in veg and always see astounding growth

Finally a definitive answer! To me it was similar to...does that refridgerator light really go off when you close the door? lol!

The answer is. Yes it does.

Btw. Have been doing some tests with 18/6 and 24/0

Didn't notice any difference between the plants grown under the different lighting regimes.

Perhaps a little more stretch under 18/6

Would love to hear everyone's opinions and thoughts about this

I use 6/2 cycle to veg and it's better than either growth wise

Thanks for bringing clarity to the topic, awesome

interesting for sure got me searching the web now lol

I've done some AF's at 16/8 with great results. Power costs big time up here in the Great White North. $1.20/KwH at peak usage times.

Roots don't die when air and light hit them. But nice fact lmao

When I used to root lots of cuttings and give them away to friends/relatives, I used disposable half-liter water bottles. They were cheap, and I could see when there was a pretty decent root system. Never experienced any adverse effects from leaving them under a light until there were visible roots pretty much everywhere along the inside of the bottle. Afterwards, I'd grab my Dremel tool, make two slices down through the threaded part at the top, and hand them on, telling the recipients to cut the rest of the way down with a single-edged razor blade and plant the things in larger containers.

If plants were all that fragile, none of them would be alive today. And, by extension, neither would we.

I think you have some point here. The absence of light actually stimulates plants to grow fastest at night. I will share the link to the article which proves this theory. Do Plants Grow At Night? - Smart Garden Guide.
