Does Light REALLY hurt your plants roots?

Ive never had any ill effect growing roots in light but the second the roots dry they become green and hard, more like branches, so i would assume that as long as they are kept moist you will suffer no harm.

this web sight needs to have a way every 1 can vote best answer may help wit confusion, and the answer with the most votes stays at the top of the thread

I support what Vostock said about a hormone inhibited by light but i read that it was also due to lack of moisture plus light not light on its own.

I too have done the same experiment as the OP and achieved the same results.

don't hide in in the forums take ur idea to support, I'm sure if you are correct admin will jump to your ideas ...?

the 'real' question here, is

How do you actually know whether one member is 'right'

just cause a heap of noobs agree with one post

don't make them noobs right!

that is the limitation of the democratic process,

thats why 'merica must be the 'world' police as

theres no backing out once you drop ur fly!

if i ran this web sight trust me there would be a way to know if the person that was giving the info was a good grower and some 1 they can trust it would say it by there name some where, people would be able to vote ther profile as a grower, im sure there is moor good growers on this sight then there are fake ass snakes,,, i actuly had some 1 tell me i can use a lil bleach to jermanate seeds and they was being serious as fuck, with that comment there who is not going to call bull shit, and as far as the voting on best awncer u got to leave that up tp the pepole it works on google and ask.com never have i seen a reply to a qustion that was voted best anr be a stupid 1,,, there is a way to weed out the snakes but you got to catch them first .....

just find the post with the most likes and read that one first before reading all the other bull shit, seems simple enough.

WOW,,,this went down hill fast....
Now stoner logic will rule and science will return to the stone age - pun intended.

Here's what I want you to do. Put a cutting of MJ in a glass and see if it roots....at the same time do one in a cloner and place it in a solo and run it along side the "light to roots" plant.
IF it roots. Start feeding it. When the algae starts growing.....See what one comes out better?

But my REAL question is.....Why do you want to have (or try) lights on your roots anyway?

What bonehead shit!

Doc

I know it is an old thread but I have something to say on its subject. I believe that exposing your special plant roots to light will kill it eventually.

I had one seed germinated in a clear plastic cup. At first it went fast from nothing to about 1 inch height(a day or so) but then it just stopped growing. Now it stays like this for at least a week. And It does not look healthy now with its leaves curling down.

I thought what the heck. I knew light to roots can be a problem I just did not think such a small plant can have a lot of long roots that can go that far, So just right now I picked the cup and I noticed that its roots are running between soil and a wall of the cup. And it is not just one root, there are a few of them that I can see. Some of them as long as a cup height.

So now I believe that the roots exposed to light for this special plant is what causing all this,

I have just put it in a black tube that completelly block any light. Lets see if it recovers. If it does then we can say for sure that it is a problem. Maybe it is ok to germinate seeds in these cups and let it grow 1-2 days but then you either need to move it to a totally non transparent cup/pot or completelly block any light coming from cup sides.

Had you received any adequate education in the most basic of sciences

you would be aware of Neil deGrass Tysons comment on Cosmos (sub in Ru)

that he claims life started as 1 cell, divided into 2

1= loving light the other loving(prefer) darkness

with the light came sugar thru photosynthesis

in Dark came rest and re charge

regardless of your own 'Play'

Biology is a science in its own right

good luck

Funny things I know a lot more on Astronomy/AstroPhysics and even on Neil Tyson's that I know about plants and their roots. It is my second grow and the first one went very well(at least 1 ounce from each plant) I was lucky I did not have these cups and went buying and using biodegradable pots for my first grow, And seeds I used the first time were bought from Altitude bank in UK.

However with the second one everything went of rails. Seeds are not germinating at all. Out of 10 only one grows(the one I was talking above), two germinated but died without growing. That was my experience with these cups and attempts to do it in soil. I even tried a paper towel method and nothing is germinated out of ten seeds there. The first time I used all 20 seeds purchased from the UK seed bank in a paper towel only thinking that only few of them would germinate but all 20 did without a single problem. Transferred them to biodegradable pots, then to big plastic ones and got 20 plants. That was too much for me so I left half for indoor grow and moved 5 outside and give another 5 to my neighbour.

All produced great buds but all of them were pollinated while inside by one hermo so I got buds filled with seeds. So I got 100s of these seeds now. Some of the plants outside dropped seeds in a soil where each plant was sitting and it started new plants. Cannot be as easy as that. That's why I started without paper towel the second time and tried to germinate them in soil directly.

it does not work for some reason now for all these seeds no matter how I try to germinate them. These seeds are less than 6 months old and still won't germinate. And the only one that did does not want to grow. How weird and frustrating it is especially that I have almost nothing left to vape from my first grow. Tried to scratch them with a sandpaper, cracked one open and no success even in a wet paper towel at all. They look to be fresh inside but do not germinate.

How is it growing in Russia now with all these laws and local police? I tried to grow 3 plants on a balcony in Moscow. It was a bit scary to be caught but it all went to the point that I just smoked just all leaves before giving plants any chance to flower.

Yes I've had a few grows like the above

Mango springs to mind

Russia on weed is like 10-20 years ago

keep growing

good luck

I don't worry about exposed roots at the base of my plants. They form a bark skin, and transport water fine. Generally I avoid clear containers due to algae (and associated problems), but for my garden veggies I'll use old plastic gallon milk jugs. I think the OPs picture is misleading. It's one sample. Try this test under sanitary conditions more typical of an operating grow system.

Ok, good news here but it is not about light . As I mentioned above I have 100s of seeds so I was experimenting with germinating them. It was not a great success with regular germination methods(soak in water, germinate in soil, germinate in paper towel). However after all these unsuccessful attempts I tried adding hydrogen peroxide. This time I used paper towel method soaked in hydrogen peroxide diluted in water, soaking in the same solution in a cup and another one with Perlite in a plastic bag soaked in the sme solution. Here are the results after 40-48 hours.

About 20 seeds in cup: I can see them all floating and two of them have sprouted.
About 20-25 seeds in a plastic(zip) bag with perlite: I need to open the bag to count how many sprouted but I can see a lot of them sprouted if I just look at it without opening.
About 10 seeds on a paper towel. I can see one sprouted.

I think the perlite with hydrogen peroxide diluted in water method is a winner. I would not be surprised if I have 50% success rate there. There is one factor though that could increase this rate in a cup and paper towel methods. My bag with perlite is on a window seal and gets a lot of sun and warmth. The cup and the paper towel are far away from the window and just sitting on a table. I will put them on my water tank for hot water and see if I can get most of them sprouted with extra warmth.

This is just great because with just normal water I could get only 2-3 sprouts out of 50 stubborn seeds. Now I have much more than I need plus I have ordered 10 fresh fem seeds just two days ago thinking that I would never get my seeds germinating.

BTW, can anybody please confirm something. I was looking for this detail for a long time and I could not find 100% proof. If my all seeds have come from feminised seeds pollinated by one hermo can I expect all the seeds I have now to be females? And does it mean they can be hermos too?

True Deno, may be algae is a reason why one I have in a pot now is not growing. Covering its clear cup walls did not help. Two days and it was not growing, its leaves stayed curled down(but green). I replanted it to a bigger pot but a big chunk of soil with roots dropped while I was moving it. So now I cannot say for sure
It is still green in a bigger pot, almost the same size as a week ago. Its leaves still curled down but the top part seems to be straighten up and slightly longer that it was.

I will probably throw it away anyway as I want all my plants to be the same age and this one is at least a week ahead.

Your overcomplicatimg things, either you suck at germinating or your seeds are mainly dead/duds.

Very rarely do seeds not germinate and if they do no complex method is needed.

Instead of peroxide paper towels and soaks find out why it isnt as simple as placing a seed in soil like me

Hormones in the roots of cannabis, are allergic to light,

the hormone does not work when light is present(I forget the name)

rootlets the fine hairs down on the roots require heat, dark,

and 02 amongst a heap of other desirables to function correctly

being a grower means you have to know your root zone its vital

many great books abound of the subject

good luck

Beautiful roots!

Old thread.
I took a clone in veg and left it in a cup. Occasionally changed the water.
It was a couple of years ago, I don't remember but I may have added a few drops of 3% hydrogen peroxide. Looking at the second pic the water has bubbles so I'm sure I added 3 % hp. Flowered and hermied and developed a few mature seeds.

Ok, may be but then try to explain why the same batch of seeds sitting on the same window seal germinating with hydrogen peroxide mixed with simple water like crazy but it has not worked with just the same water without hydrogen peroxide?

The temperature on a window seal at night is about +15 but it again does not seem to be relevant as it has not affected germination using H2O2.

I can only explain it the following way: all my current seeds came from my buds and are covered with a lot of oil, I did not even care to store them properly for 6 months as there were inside buds in a clear plastic container.
They also have thin layer of casing(pouch) on top of their shells. Without hydrogen peroxide water cannot get break this casing and oil layers sitting on top of a seed shell so there is no water coming inside for it to grow and crack its shell. H2O2 though breaks this pouch and penetrates/breaks oil layers.
It is not even may explanation. This was explained in some video on youtube for old bag seeds.

Now with my successful experiment as for right now I have about 20 seeds germinated with three different methods that all have h2o2 mixed with water.

UPDATE: Actually I have about 30-35 geminated in a cup of water and in a zip bag with perlite altogether. In fact so far I can see only five that have not germinated.
