White fuzzy mold on medium

[DasPachy]

As the title stays, it's white fuzzy mold looking stuff, and it is forming a thin layer on the surface of my growth medium (potting mix). Any ideas? It's particularly bad in one pot, the others just have small isolated patches of moldy medium. Help!

I had the same prob last week. I'm no expert or anything, so this is what I did, try at your own risk:wtf:

When temps are cool, encourages mold to grow. I dropped my lights, quit watering, got temps up to 78, humidity 30-35% range.

With the up temps, I turned off fans next day and removed the dried out layer of topsoil from around plants and threw away.

I have kept the temps up a little higher than I usually do since then. After transplanting I have not seen any return of mold.

I am using 24-0 right now so I used dropping light to raise temps.

Hope this helps. I hate mold.

Lower the humidity as much as possible. (below 50%)

are u sure it's not just alot of salt buildup?


a few weeks back i had what looked like white fuzzy stuff all over my hydroton but it turns out i just let alot of fertilized water run over the hydroton and when it dried the salts were just left over, but it looked like mold

Get better fans going and keep RH below 50%.

Stinky - I hear you on the fans. In the mean time, any good dehumidifiers you could suggest?
