there is this stuff that keeps developing on the soil. its this white sorta powdery stuff that appears to be mold. its not on the plants at all, and im not sure its actually mold. it sorta developes on any protruding little stick or clumps of dirt around the top of the soil. im wondering how this will affect my girls in the future, and what can be done to get rid of it. they are still veggin by the way.

Mold typically likes a humid, moist environment. Keep the soil a little on the dry side. Water with care and only as needed. Also, try to give the plant more light and it should go away. If the mold persists, it may be your soil. get some new soil with adequitte drainage so the moisture wont hang around and cause more mold growth.

White mold grows kinda like a fuzzy cotton ball on the clumps of the soil. If yours looks kinda like this then it is a moisture problem. Clean off by removing the top soil around it and along with it. let the top soil dry out for a couple of days, then proceed to water as you did before. If it comes back, try a different soil and or get better air circulation going around the plant. Most forms of mold don't grow in light to well if at all. More lighting can help.

On the top of the soil? Mold?

Are you talking about nutrient salts that collect on the surface and dry to a powder-like stuff? If that's the case, it's nothing to worry about.

Yeah Potroast is a great guy. Anytime I needed help he has always been there to answer my questions. People pay him for his services that he gives us for free. I am glad to have him as a grow buddy. I have found that if you mess with him and bother him he will get pissed. He can be a grumpy old man. lol. He doesnt like a bunch of pm's about stupid shit either. Who does? I would like to make it mandatory for him to smoke a blueberry joint while he post if I could. lol. So he can relax a bit. Im still waiting for him to beat up the knowm. lol.:mrgreen:

It sounds as if your plants have been attacked by powdery mildew. This is a mildew closely related to fungus. The powder is the mildew's reproductive spores. It thrives in an acid environment in a temperature range of 60-70°F (15-21°C) with a humidity above 50%. The spores are floating in the air and there is no practical way to screen them out. Instead, try to change the environment so that conditions don't match the mildew's needs. This may require raising the temperature or lowering humidity.

[SIZE=-1]Dusty white or light coloured coating on leaves and other tender plant parts. Symptoms are worse in late summer and early fall because the disease is worsened by cool nights and warm days. Plant parts will slowly decline in health and may result in dwarfing, distortion, chlorosis or browning of leaves or premature leaf drop. Small black specks may also been seen late in the season on plant surfaces. Generally, powdery mildew is not harmful to a plant but can decrease vigor and aesthetics.

Powdery mildew is a fungus that spreads by wind, and prefers moderate temperatures and high humidity. Growing conditions such as close spacing, densely growing plants and shade can promote disease development. Powdery mildew can over winter in buds, other plant parts and in debris and can continually reproduce indoors.

Thanks for the kind words, WM, I think.

I AM a grumpy old man! And I DO smoke while I'm on here, it's the only way I can do it, by laughing constantly.

Plus I've been answering growing questions on the net for 9 years now.

I believe that I'm deserving of a little crust. :blsmoke:

I don't know for sure how much this may help.
I have made it a practice to regularly turn over the top 1/8 to 1/4 inch of the soil mix in each of my containers with my fingers….. I do this every few days. I read something about the benefits of this practice years ago,….. can't recollect clearly where.
My point is that I have been doing this for a long time. As the surface, if left untouched, has a tendency to mat…..I think this technique aerates the soil better also. I think the plants enjoy this!

I'm having a similar problem and I just found this:

There is white stuff growing on my Grow Sponges (or plants).

Sometimes people notice a white fuzz developing on the surface of their Grow Sponges, especially when the plants are small. This may be a fungus that is decomposing any seeds left behind in the Grow Sponge that did not sprout.

If your plants are still small, you can usually remove the dead seed by following this procedure:

Remove the label (if you can) from the top of the pod by making a cut from the center to the edge of the label and gently peeling it off, being extremely careful not to cut or damage any little sprout stems. Save the label, as you can put it back in place like a collar later.

Gently open the Grow Sponge and see if you can find any unsprouted seeds, and if you do, gently remove them with tweezers. Once the dead seed is removed, the fungus will die off.

If you have a fungus that is starting to grow up the stem of a little plant, do the procedure above first as it is most likely the source of the problem, but in addition, dip a cotton swab in a bottle of hydrogen peroxide (available at any drug store or supermarket), and very gently daub the stem of the affected plant with it. This should kill any fungus.
