The roots won't retract away because of light.
look at this, not an issue. These are the roots of cuttings taking but I have plants in flower full of roots wrapping round n round, exposed like this and it's no problem. I can't see that the light has any effect on the roots.
Id take a photo now to show you but lights are off

and there's no way them tiny plants have used up all the nutes in the soil yet, repotting won't hurt though.
patience is key
I think it's caused because of the water running down the edges of the soil when it's dry more than it soaks in. I was gonna cover them up but I had no problems so left it. I think roots know they're underground because of the environment they're in, not because they're in the dark, I see no sign of green on them or nothing unusual.Im glad you showed this. But i have to say the way the roots are growing looks like they are attracted to the light and head straight out to the edge and straight down.
Im only commenting on what i can see.

If a root brakes through the top soil that's different, it may then grow a shoot not cos of the light but because of the change of environment. That's my current theory anyway.
And bare in mind the lights are directly above the plants so if the roots were attracted to it surely they'd grow up, not down looking for light?
Of course they would... because roots grow. That you've forced them to grow in an environment where light hits the outside of the containers cannot be helped by the root system. The roots will still grow. They will just grow away from the light as much as they can. The roots on the outside of the pot will adapt much like a root exposed on the surface... their effectiveness as a root questionable.I agree it would probably be best not to have the roots exposed to light but from what I witness personally the roots don't seem to react to it in any noticeable or measurable way.
If roots actively grew away from the light then they wouldn't be visible in my photo would they?
Your quoting Darwin and other texts you've read but I'm telling you from real life experience. The roots do not grow away from the light nor do they grow towards the light,nothing noticeable anyway, nor do they know to grow downwards, they grow towards water and nutrients.Of course they would... because roots grow.

I'm not just making this shit up. It's real science. First observed by Darwin. If roots grew toward light as claimed in this thread then how would they know to grow downward? Plants, that's the stems, leaves, and roots are all light reactive. That it doesn't seem to harm your plants doesn't carry much weight when you consider all of the scientific research that has gone into proving that roots are light reactive.
Perhaps any effect the light has on the roots would be more noticeable in hydro as all the roots would be exposed where as in a clear container filled with soil like mine the majority of the roots are still hidden by the soil. I've got 15 plants in containers like this in flower wit no problems, I was going to cover the roots because I thought the light would cause a problem of some sort but 've had no issues. I've got no reason to believe the exposed roots aren't doing their job, or behaving normally, they're obviously growing, winding round and branching off.
@skh You tried to tell this guy who started this thread that his cups were letting to much light through and it could be causing problems, that is absolutely not true

I'm gonna have a read through the article this evening when I get a chance.You may feel that there is no problem and if you are happy there isn't one. But those rootballs are not optimal. And the article I posted explains that they suffer from more problems as well. I want the best results i can possibly get and in text and visually I can see roots should be kept in the dark.
In my opinion from all the facts shown and discussed and my own experience. :)

I absolutely agree roots would be better off in the dark but I can't be bothered to wrap 15 bottles. And it's not like I have the lights shining on the roots. The bottles are packed tight so it's minimal. Definitely agree dark would be better, I'm not suggesting people start lighting there roots, am simply saying there is no noticeable deficiency or damage to the plant caused by it in soil, the effects cannot be realised by looking, a measured side by side grow would be needed to show the difference.
But light on roots as a reason for the issue posted here is way out there
Sorry , worded a bit wrong. I didn't mean you said that the issue could be light on roots. Your knowledge is evident as I read your stuff on here, i know you wouldn't come out with thatI didnt say it was. I said likely overwatering and agreed the roots may have grown like that due to it.
I did not know the answers to the roots questions posed so i researched and posted my findings.
