Make sure the rockwool is only moist when your finished doing this. I think if you do this now you might have a chance in saving them babies.If you dont have a ppm meter, go to the shop and get a few litres of bottled water, no carbonated. Fill a tuberware container up with it, PH it down to 5.8, get a glass, fill it with the pHed water, submerge the hole rockwool cube in it, take it out, cup your hand round it, leave a space between your finger and gently flick your wrist. Then get rid of that water in the glass, fill it up with the pHed water again, and repeat that 2 or 3 times to all clones. Leave them until tomorrow, and only feed them water.
Have you any photos, of anything ie. clones, medium, propagator things like that?Its sponge material, it might be peatemoss.
I never mist my cuttings, unless they have not rooted in about 2 weeks and then only once ever two days. To Much misting makes the plant not need to grow roots for moisture. FDD taught me this about a year ago.Yes, i have a dome over my hydroponic system to keep the humidity. I spray the whole inside of the cover to increase humidity. I did this 2-3 times a day.
