Imortant question about roots

[dougefresh]

Hello,

I had just started my plants about 2 weeks ago and the roots are in the water of the hydro system, but there seems to be a problem. There is brownish yelloish stuff growing on the calk i used to old down my tubing and the brownish yellowish stuff is on the roots also?? does anyone know what is growing inside there (fungus or algae?) and how bad is it for the roots?

What kind of hydro system is it? There should never be unaerated standing water in a hydro system. Please give some information about your setup. Pics would help.

the system is very simple i used a rubermaid container and a bubble stone... it may have been becasue the tubing came out of the bubble stone and there wasnt much air comming thoguh...but I will take a picture today and post in on my next post

Sounds about right. You REALLY need to be sure that your reservoir is properly aerated at all time. Scrub the bubble stone with a toothbrush to get all the crud off it before you hook it back up again just in case it's clogged. Check your lines for obstructions. Technically what you are doing is called DWC and there is a lot of good info for you in the hydro section.
You'll want to treat with peroxide. Look up threads about slime on roots in DWC- I think there are a couple kicking around somewhere.

What type/color of rubbermaid tote? Even the darker ones will allow ambient light to permeate through to your nutrient solution. Water + nutrients + light = algae... and the more light, the more algae. H2O2 will work, like Stinky said, but you should also check out the excess light and see if it is a problem.

well i fixed the system, its a dark blue rubbermaid..I cleaned everything but the slime wont come over the roots unless i touch it and kinda pull it off which i do not want to do, is there any other way to get it off?

i don't know about getting rid of it other than what was said above u do need to clean ur res out scrub it down and when u start over do the h2o2 and hygrozime is a real good product + clearx i think it's called it's a water treatment that is good for the water those 3 things with ur res with no light leaks and you'll be set
