clone mold

[HIWAY]

I took some clones about a week ago and when i checked them this morning there seems to be a white mold on the bottom of the tray ,and the cubes and some plants
I have them in rockwool 1 by 1 cubes in a tented tray and I spray them with water 2 times a day
all was looking good untill today
I have transfered them to another clean tray but I don't know what to do about the mold on the plants ?
Please help

They should be rooted by now, or at least close, get some air moving, vent the tray or remove the top. Im not sure how to kill the existing mold, and maybe you cant. Just hope the mold didnt hurt the forming roots. But they must still be looking ok if you are asking advice on this. If you are using 24 hours of light than stop this on these, mold grows in light.

I have them sitting in a window for light
I figured that this is allmost the longest day of the year so i am using natural light 6:00am to 9:00pm but should i transfer them to indor floresent lights for more control?

I don't know what kind of trays/domes you are using, but a vented dome works wonders. Don't mist them twice a day, there's no need for that with the dome on there.

When I take cuttings I put them under the dome, water the cubes, mist the leaves and leave it alone for about a week. After that week they may need some more water, but I don't add much and don't mist the leaves. The humidity in the dome is already going to be really high, misting the leaves is redundant and will just invite more mold.

Is there annything i can do about killing the existing mold? or
if i leave the dome off will the mold dieoff

You need to clean the trays and cut off all of the mold you see. Try to salvage whatever is left. The mold will only continue to grow.

Yeah I probably should have said that, the nice thing with rockwool is you can peel away sections, so you can probably get it off.

Now is this "mold" webbie and stringy or is it like a powderyness?

Could just be salt build up from you spraying. Rockwool always gets that and so will the trays and the plants if you spray them that often.

Are you using tap water?

yes plain tap water ph 6.0

I find it best to spray the inside of the lid of the dome and the plants will draw in the moisture.the dome only should be on clones for a max of 1 week then remove and let the plant form a nice root mass.once out of the done spray the cubes.good air circleation is all that is needed to sort out this problem depending on how bad it is.

I'd be willing to bet you aren't seeing mold. You are just seeing hardwater build up on the cubes and on the tray. Mold wouldn't really be encouraged much to grow on the tray itself. Just stop spraying, maybe try cleaning the leaves with a damn rag and try to get some RO water.
