Mould on top of substrate
Dat_Maltez_Loudstarted grow question 4y ago
There is some sort of mould on the top of the substrate. I think I will spray it with diluted hydrogen peroxide.
Is this a good Idea?

Bud Rot? Mold? Or safeOne of the branches split during a storm the other day and didn't recover after a few days so I chopped. I'm wondering if the leaves trap moisture in the bud during the days I let it recover. The backside has a brown tint to it while the front looks green and healthy. Srry 4 picsBuds. Other

Mould on seedlingThis 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?Other. Mold

Possible mold issueI've had a drastic change in smell... overnight. Smell went from very pungent to an earthy almost musty smell. Could this be a precursor to bud rot? Or is this sometimes normal? Humidity avg 50-55% during day and no higher than 65% at night with constant ventilation/circulationWeek 11

This is my roommates plant. I think it’s starting to get some type of mold on it. He sprayed it down with baking soda and water I guess, not sure how effective that is. What do you guys think it is? And what should he do?
