Mold and powdery mildew

TheColonel420started grow question 4 years ago

Hi everyone. I have seen some of my friends suffer with mold issues in their grow tent. How can i keep mold out of my grow tent? Thanks My set up during this winter is to have the extraction fan off with a fan pulling in fresh air into the tent. P.s. i do not have any mold yet

If plant is too bushy(try defoliation so air flows better), Try to keep humidity around 40-60% when growing and 20-50% when on bloom because fat buds get mold if too much humidity and poor airflow. I also recommend disinfecting the tent and equipment before next grow. I hope this helped you, Good luck with your grows 🙂

Just watch your humidity and spraying the plants. Issue comes more from ppl doing same practices on LED as would do with an HID. LEDs don't get warm to evaporate the moisture.

How crucial is an exhaust fan and a carbon filter?I cant find anything in my country as a kit, but would buying them piece by piece work? Example something like in the photo connected to an air duct and then to a carbon filter? Or if the exhaust fan is not crucial? how can i get rid of the smell in a cheaper way?

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

CO2 depletion in the tent, under light. How much?You have a tent with a plant and a co2 sensor. When you have 1000 ppm in the tent, and you turn off the ventilation, how long does it need to get under 400 ppm? Please many answers! 🙌👍 How much watts has your light? Dimmed down? Give the resulting wattage.

Mould on seedling This seed was late to spawn. Now it finally opened, even if it's quite short on the soil. I can see a fluff of mould just below the cotyledons. What should I do? Can I save it or do I risk contaminating the rest of the plants in the growbox?

Well I messed up a little I just pulled out my sticks I was using to label my seedlings and I find this white mold on them. I removed the sticks and dirt around should I use an anti fungal thing? I already have had gnats too but treated for them. This living soil is no joke eh

New Light? Find a way to raise light? More Fans? Combination? (Light: 44" above ground level | Tent Height: 63" Day avg: 78.6f) Should i worry?What do you guys recommend as far as lighting for this tent? I have a 300w led light but at the height it's currently at it is producing a large amount of heat with my exhaust and two oscillating fans? I also have other plants in with my seedling so could the humidity cause it?
