I’m doing an outdoor grow and I noticed an odor of mold coming from the plants . I checked the plants but seen no mold . I bent down and smelled the pot and that’s where the smell is coming from . It’s in a 10 gallon fabric pot just sat on the ground . I thought about moving her get her off the ground but she’s very heavy rooted into the ground . She grew right through the bottom of the pot with thick roots . She’s in flower 2 1/2 weeks now and don’t wanna mess her up .
What can I do to get the mold smell off the pot .? Thankyou so much.
Be sure to let the soil dry out between waterings. It will help mitigate mold.
You can spray the outside of the pot with a dilute peroxide spray, and that might help, but don’t overdo it and don’t directly spray the soil. Doing so will kill the beneficial microbes in your soil.
If your fabric pots are sitting on the ground, the bottoms may never dry out contributing to the possibility of mold. I don’t have any experience with that as I grow indoors with the pots sitting on wire racks.
My advice is that you don’t disturb the roots this far into it. Roots already grew through it, so your tossing the bag anyway after this grow. You are super close to finishing up, don’t upset the apple cart as they say. I would second the motion to use a 4-parts water, 1-part Hydrogen Peroxide in a spray bottle to lightly mist the outside of the bag over a few days, but that’s about it. The plants look good and if it’s just the smell outside, let it go. The H2O2 will help with the smell. Love the plant risers shown in the thread too for the next run. Take this as a teaching moment and you learned something new! Perfect example of gaining experience.
It looks like you got char and all sorts of goodies in that top layer. In addition to active soil microbes on top. Char is literally a brothel for benificial microbes. I think you are smelling the happy microbe brothel and messing with it would be counter productive.
That plant looks great and you are going to hurt the flower production of you uproot those tap roots now. There is probably more in the soil now than the pot even. Outdoor in northerhemisphe you are well flower and no longer veg. Please do not rip up those roots.
I beg you….
That stem looks perfect. No cracks, kinks or blemishes. If it was bad mold it would be trying to slime mold up the stem by now.
Thank you for the response. I will not uproot the roots . I’m just gonna live out her life where she is . Thankyou for saying she looks good . I tried hard . Still a newb but I gave it my best .
Ty so much . Yes I definitely learned from this . And next years grow will definitely be off the ground on those pot risers . Hoping for a big harvest off her
I would agree with @noddykitty1 , @Tryingtogrow . Everything below that line and a few in the center to open it up for airflow. Never more than 20% of the plant total and then give it a week to recover. Hope that helps.
Or root rot, and sitting on the ground creates a perfect environment for it. Matter of fact, I’ll bet you a doobie that “moldy smell” is rotting roots.
I would agree if there was any symptoms. But symptom 1 is droopy leaves; then rapidly followed by yellowing of leaves. None of those are the case here. That plant is shining and happy.
Grow bags outside usually have the exact opposite problem. I live near seattle and fall rains f up more grows than I could ever tell you about. But never once has root rot without plant symptoms arisen for me even in our wettest of rainy falls. They are hard to over water outdoor. Usually, the opposite is true. Too dry followed with annoying hydrophobic soil. Doesn’t matter if it’s 30 gallon or 3 gallon. I often countersink them 2-4” into the ground to keep some residual moisture around and let some roots grow thru. Exactly like the original poster.
I am definitely not saying you have not experienced root rot, or your experiences are wrong. I am just saying with what I have experienced it is exceedingly rare outside in a porous grow bag. Even in some of the wettest fall conditions of North America.
Also, the bag pic showed active growing saprophytic fungus. We pay top money to inoculate myco boosts. Makes no sense to toss it out when it fruits on the soil surface. Those are excellent to have on your living soul soil. And yes they smell like moldy leaves.
I agree, probably the micro heard. You’re probably smelling the mycorrhiza of a happy pot with healthy biome. Does it smell like outside after it rains or does it smell like rotting and foul?
