Beginner to the whole growing process and am wondering if I have a rapid rooter tray that holds 50 rapid rooters, is it viable to germinate 3-4 seeds and not have to use the other 46-47 slots? Along with this question, I'm inquiring how much water would be needed for the 3-4 rooters and honestly might be tempted to just go in and do 5-6, so if there's anyway I can get a recommended feeding schedule and the SPECIFIC amount of water (and type of water, curious if it needs to be PH'd or not) needed in order to successfully germinate these seeds it would be greatly appreciated.
