Mold in rock wool ?

PinkParrotstarted grow question 2 years ago

Hi everyone, We are at the 19th day of hydroponic growing with rockwool as the only substrate. Our system is the ebb and flow 15/15 :) Do you have any ideas? Maybe you can help us!

If you are using enzymes then this is normal, by product. or any PH adjusters its just Salt drying in.. defo not mold pal. Stop wetting the rock wool. The roots drink not the stem.. Good luck buddy. Is

It could be mold, but also looks like calcium buildup from hard water. If your plant does not seem to be affected, I'd just watch it. If your plant seems stressed, I'd be doing some cleaning. I grow in rockwool and have experience similar and it was just hard water.

This is SPARTA! Get that out of the grow space. Clean all your equipment, learn from the mistake and mive forward. You don’t want any of that mold in your space, or in your body with the end result. ❤️👊🇨🇦

Ciao! Mmm la muffa non va bene, attento che non sia partita dall'interno, dalle radici! Mi sembra infatti proprio quella muffa che parte dai marciumi radicali.. Non ho mai usato il metodo ebb&flow, preferisco dwc oppure drip system :) poi attento perché mantenere la lana di roccia "scoperta" andrà a rovinare le radici quando saranno alla luce! Devono rimanere al buio.

Germinated seeds not sprouted yet I germinated 6 seeds that all after 4 days had cracked open and showed small tails. They were put in small pots with soil + perlite, soaked in ph 7 water. It’s been 6 days now since they went into soil and none have spouted. Wait more or disturb the soil to inspect the seeds?
