Have seedlings here and they are about 3 weeks old and have grown out of the sides and bottom of their rapid rooters. I have a 14 plant aero rig in a 4X8 room that is sealed, temp and humidity controlled, insulated, with vapor barrier, and mylar wrapped, with a 1000 watt cool tube for them to mature into, but that seems like overkill at this point. I have read that going too big too fast is bad, I have also read to drop your rooter into your basket with clay media, set your timers and turn on your rig and walk away. So thus my question of what should I actually do?
