White dusty looking stuff
GeekSayWhatstarted grow question 4 years ago
I have a pure white substance on the top of my soil, should I be worried. My RH is at 50% and temp is around 26 in the day, and 21 at night. It doesn't seem to be effecting the plant at all. What should I do?
Thanks

I had the same on mine. Just scrape away all visable areas and dispose of. Can add more new soil if you like but let the top dry before watering again. Hope this helps

Mold on stored coco/worm castingsHey 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!)

Mold ??Hi,
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?
My plant will be going out there and I am worried.

Fungi in floweringFound fungus on a girl's leaf. my first actions were to carefully remove the leaves that were contaminated and the excess leaves to improve ventilation. I also washed the Grown with disinfectant. What should I do next? It's 4 weeks to harvest, should I anticipate it to avoid

How do I reduce humidityI have my grobox in the loft but it's got very high humidity 60-80. What's the best way to get it down to 40-50% for flowering? I already have a mini dehumidifier, 2x fans in the box. A dyson cool fan outside the box. Any tricks? Can't afford to spend mad money
