How did you cut the bottoms? In order for the roots to sprout they have to be cut at an angle and then the other side has to have the outer stem shaved away with a razor blade so there is lots of the inner stem expose about 3/4" inch up from the bottom. Is that what you did? My have been 7 days and just starting to show roots through the rooter plug. I keep them in a mini bubbleponics I made for this purpose and then I put a dome over them. You cna use the recommended amount but watch b/c it will make your Ph jump up to 8 a few hours or the next day after. So you will have to Ph the water back down. Once you stabilize it it stays. It's the Root 66 that does it. How much light, how much water/moist is the root plug?
