how long shud it take for your germinated seeds to sprout up into seedlngs ? they have been rooted then planted since saturday (now tuesday) but as of yet still no sprouts....a bit para i mite have overwatered, would this do any harm ??
patiance grasshopper... yes it is possible you over watered them but all you can do at this point is wait and see.
If you are in rockwool and you pick up the blocks no water should come out...same for any type of water holding media, the media should be wet/damp but not dripping
