Here is what I am working on. The right side of the table is where I am going to keep my mom's. I haven't put a top on yet. Currently there is about 26" clearance inside that tall section on the right. The lower section is where I will keep clones and it's about 14" clearance, both of these number are above water line which will be a 4" flood. I'm not real happy with the way the top tray turned out. Everything is squished on the left. My thought is to extend the top tray all the way across and sacrifice some clearance for the mothers. So bottom line: can I keep my mom's happy with 14-15" clearance above water line? I need about 6 - 9 clones every cycle is the current plan. I will likely keep 4 mothers which means I wont be getting around to each mom for a while. Is 14" enough clearance?
