I use the rapid rooter when I clone, I like them a lot because of the presoak factor. I've used a heating mat before too, actually got better results. If you do use a heater, make sure the thermostat is near or on the mat because it needs to read the temperature of the mat not the inside of the dome or whatever. A few months back I almost lost my Church strain because my puppy knocked the thermostat off the mat. I was using a waterbed heater mat instead of going out and buying a actual cloning mat(both have thermostat controlers) and their almost identical. Anyways, the room temp was about 70 and the mat was set to 82. The thermostat kept on reading that it was 70 so it just got hotter and hotter. Eventually I had 35 melted clones and 2 melted trays. About 5 of the clones survived this horrible incident.
I'm going to start giving my clones the tea to see how well their root structure starts to develop. Before I just fed them some flora nova grow with superthrive which has worked great for me. Got amazing results everytime. I'll use that with the tea this time and see how they do.
