Ok, so I've done a little more research and have found out that rockwool retains up to 60% water. That being the case, should I not be watering so much? My seedlings are going to be ready to be transplanted in my e&f system by this weekend and I don't want to start overwatering them off the bat. I'm thinking maybe start them watering like twice a day at first for 15 minutes at a time and then slowly increase their watering schedule as the plants grow. Anyone that uses rockwool have any recommendations for a watering schedule in an e&f system?
