mold on rock wool

[Koabear]

has any one encountered mold on rock wool cubes any advice

I haven't actually had it, but I have heard of it. How did you acquire the mold? Did you buy them that way, did they get mold while you used them? Can you be a lil more detailed? I have been curious about this as well, seeming how I use rockwool.

well i have a dwc setup with rock wool and i have a touch of mold on the top and looks to be close to my roots i have Dutch master zone and hydro pro oxide i am using i need a remedy

i dont use rockwool, but i have seen many many growers cover it to prevent that... a neat idea i have seen used a few times is cut a paper or Styrofoam plate to cover it... just trim the plate to what ever size it needs to be to cover the rockwool then put a hole in the center large enough to accommodate how big the stem WILL be and finally make a slice in the plate so you can slip it around the stem.

i thought that was a brilliant solution myself.

no light and the green growth dies.... simple and cheap.

tried that didn't work . mold like to grow in dark places. that pervent it form happening, one is on i need to kill it. i need Fungicides, names of products you have used please

sorry, wrong guy for that... i was thinking the green algae at the top of rock wool... my last grow area was totally climate controlled so i never got plagued with molds and this one is too much of a cluster fuck to let mold live

serves me right for trying to help in an area i have no experience. my bad.

Never heard of moldy rockwool is it affecting the plants at all? You sure its no algae?

ive allways grew in rw and i allways get green alge or blackish mold buy some covers and put them on it will help, the main problem ive had is if you touch the alge/mold it smells like dirt and it make my tree taste that way if it gets 2 bad

i have covers man i have white powder over my cubes and i already went to home depot and bought a fungicide that is for fruits and plants so i will tell you how that goes

 

[raidercelticfan]

when mine get 2 bad i spray them with high pressure water it nocks all of it off

I am using rockwool in an ebb and flow style and it has the same green stuff i think might be algae, and then the white stuff you mentioned, lemme know if you find a good way around it
