Hi all i have these grow bags that were used I scrubbed them up a bit and used them for my greenhouse grow. Its starting to show this red and the normal green algae or fungus. I dont run into the red indoors and not sure if its bad or not? Can anyone tell me whether this is bad and if so what is the best way to handle it. i haven't had any issues with the green algae. Thanks weed family. The plants are currently immaculate so they arent showing any issues I just want to understand what I'm seeing here and if its ok or not?
It has to do with salts in the fabric and possibly what your feeding them. What did you wash them with? Consider getting the bags elevated a bit so air gets all the way around the bag. More oxygen to the roots the better
I just brushed them with tap water from the hose. It very well could be from heavy feedings before. I wll make grates to sit them on. Thanks for the help I wont stress on it too much until I seem to be having a problem.
