what do i do im 1 week into flower ing and have brown roots on say 50 persent of roots on the bottem of the tray in a ebb and flow what do i do is this normal

Welcome to the forum ctec. Brown roots can be a problem if the roots are mushy. Have you noticed any difference in the way your plants look. You say 50% brown roots. Are you using the h2o2 we talked about? What medium are you growing in, sorry I forgot. VV

yes im useing 80ml of h202 in a 52l tank every day and im growing in a ebb and flow witl 4 inch with clay pebbles one inch cubs ill see if i can find a pic

If the plants are healthy looking above the clay pebbles then there is probably not a problem with the brown roots. Things to be aware of: the water temp can affect your grow, roots should not be exposed to light unless absolutely necessary. The h2o2 will kill any pathogens that would harm the root system. The ebb and flow system is one of the simplest most forgiving systems you can use. It sounds like you are doing fine and just don't know it. Pictures would definately help. VV

yikes - if i saw brown roots i would be concerned too...
never heard of brown roots being normal. is it clay resdue from your pebbles making them brown? is your resivor water "brown"ish?

nope the water isnt brownesh

Are the roots mushy? dejavu. If they are you must have to high of a temp in your reservior. If not..... VV

I've seen a situation similar to this... one of my local hydro shops was sporting a large ebb & flow table right in the shop's front window with six tomato plants (trees, more like) flourishing underneath an air-cooled, 600W HPS lamp. There was no hydroton in the table, only in the 10-inch mesh pots which housed the plants. The roots were spread across all four corners of the table and the mat was at least an inch deep. The roots themselves ranged from medium tan to dark brown.

I asked the guy who runs the store about this, as the plants themselves were obviously quite healthy and were fruiting bountifully. He explained that the intense exposure to light was causing the discoloration, as was the particularly dark nutrient bath he was using. He pointed out that none of the roots were fuzzy or mushy, so while they didn't look argent at all they were certainly healthy. Other than a few bugs eating leaves occasionally, the plants completed their life cycles without any problems whatsoever and produced several pounds worth of fruit.
