Structual Mold

[tweder8002]

Hey There,

So i just finished my first harvest this past week and i went into the flower room to do a huge clean job before i put my next set of teens in there. I looked behind the mylar and all of my walls are covered in black mold. Huge colonies of black spores. They only seemed to grow where there was no direct source of light. (behind the mylar). So i pulled all the mylar down swept the place up and im about to go to town with a spray bottle of bleach and some killz. Is there anything else i can do to prevent this from happening again besides what i mentioned. The room is flat white now and im debating on just leaving the walls white and saying forget the mylar.

So if anyone has any further advise concering preventing or curing this mold issue im all ears. (or eyes) Just hate mold and need to get this taken care of ASAP my next batch of ladies is very eager to get into flower. Thanks in advance....

I'm not sure if this will help you or not tweder, but I saw it in another forum and will post it here for you:

"I use my home-made sulfur burner on mold problems. while using the sulfur burner, all ventilation is turned off, of course, so I do the sulfur burner either the hour before the lights come on, or right when the lights go off - if done after, the fans are utilized to clean out the sulfur for a short bit once the hour is up, otherwise you will suffocate the plants if the sulfur is left in there overnight.

I just use the heating element from a coffee maker. the sulfur pellets burn in a tuna/salmon fish can."

Hmm interesting, I may look into that ive heard of other great reasons so use sulfur. (pest control) Just kinda wierd that it will kill mold but not harm the ladies.....

If it isn't aired out properly it will kill them I am assuming from that post. I think you should do the bleaching and KILZ before your next crop and see if it helps. Maybe you can still use the Mylar if you clean the back with that bleach solution and dry before re-hanging it? :what:

Not sure if they still make it, but they used to have an anti-fungal you could get at the paint stores to add to the paint can before painting...I used it in a basement hmmm, long time ago, and have never seen mold in there since. It was a long time ago tho and that's all I remember about it.

Yep use the Kilz, ditch the mylar. I am very allergic to molds, I can smell a house with mold from the outside I am so sensitive......

The plastic against the cold wall (I am assuming concrete....if 2x2 wall you need more work) keeps a very humid environment as the concrete will be releasing the water for years after setting.....perfect environment for mold and the black mold is bad, bad stuff.....full strength bleach my friend, full strength and maybe some alcohol too as a final wash.

Flat white paint seems better than the mylar and such but every few years it is necessary to repaint as it does yellow a little.
