roots exposed to light

I was thinking about this ...

everyone knows that light is bad for roots right?

but when i read posts by Earl with his crazy assed space shuttle system, and Stinkbud with his Aero/NFT system they both have heaps of roots all over the place.

They have photos of kilos of roots, they chop them off in masses with no damage, etc etc.

Anyone that has done DWC or Aeroponics has exposed the roots heaps of times.

Then i look at Al B Fuct and his cloning thread. You can see the roots out of the bottom of the rockwool in every photo. In fact he waits till the roots are well exposed until he plants them.

Obviously roots do have a tolerence to light. How much i dont know, but they do.

so the question is : HOW MUCH ??

awesome link!

Clear plastic bottles for pots, kitty litter for medium, CFL, and well over 1 gram per watt.
if its true hes the weight per watt king!

So far as I understand it, It's not the roots that suffer, but the nutrient solution or moist soil. When exposed to light, it's perfect breeding ground for algae.

I don't see many roots that could be exposed in his kitty litter. light allows bacteria and fungus to grow. do you have a problem with your res when you allow light to get to it? yes, same thing here, lots of good nutrition in those roots for bad things to eat. I use black landscaping fabric to block light. I wouldn't ever think about using kitty litter to grow in. who knows what chemicals could be in it, or what it might do to the ph. fish tank stone works well. it's clean and inert.

so if you water once a day and run to waste (not back to res) there shouldnt be a problem ? < thats a question BTW

EDIT : the omega garden foodle has roots exposed to light and air the whole time and its a commercial system

so i put forward that in fact you can have roots exposed to the lights as much as you want.

mine are in clear bottles and the roots are fucked up. white fuzz man, slight root rot, and my leaves are fallin off, almost a month in flower but there are no stores this season that are selling pots and shit. i've tried hydrogen peroxide in small doses and that doesn't do shit. for the newbs... don't be real fucked up when thinking up ur grow room. roots need dark. makes sense.

if a commercial company does it then it MUST be ok to do! I also trust the news and media and always follow fads. can't ever go wrong this way
