alright well im having trouble cloning, hopefully someone can help me.. well i have tried every thing from cloning with soil, rockwool, water, a bubble cloner and i have got nothing to root...well i have a 20 watt plant and aquarium light on them, i do use rooting powder, right now they are in a humidity dome in rockwool cubes, that is in a wooden treasure chest so it is hidden. i first thought maybe there not getting enought air but with the humidtiy dome the dont get much any ways. i have soaked the rockwool in 5.5 ph water. i do not have a heating pad yet. temps are at like low 70's could my problem be fixed with a heating pad?my main question is having temps of low 70's will that not let them root. if you have any tips or ideas plz let me here them.. thanks..
