Mold on stored coco/worm castings

rando_herberstarted grow question 4 years ago

Hey all, I mixed together 40L of Coco and 10L of worm castings, and left it sitting with a lid. Sure enough, it has some mold growing on the top. Can I still use this medium or should I just throw it out? (Not broke, but cheap!) Thanks

This is exactly what should want. Beneficial fungi and bacteria allow for organic nutrient exchange.

Depends on what kind of mold it is...I'm not toi familiar with coco but I grow in living /super soil, so some mold is beneficial and bound to happen when you add certain products. My mold appeared when I added malted barley but after a quick Google it appears to be good mold beneficial to the soil microbes and plants seem healthy. Check out my current grow...

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.

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?

Genetics or budrot?Hi all, my Royal Jack Auto from RQS is in 7th to 8th week and on the tip of the main cola these red, brownish spots appeared. Humidity has been 50% yesterday and before 40-45%, plenty ventilation in the tent. Around 24 to 28 °C. Could this be the start of budrot or am I paranoid?

PM covered plant sentenced to death - What would you do?I'm about to destroy this plant. Each branch has heavy PM despite having ample airflow. I suspect due to the lack of direct sunshine, but I'm sure it's spread to other plants which will also be destroyed. Is there anything I can do to salvage? What would you do? Thanks!
