Yeah, I've been watching your ICE grow. Very nice. The attached pics were taken about 9 days ago. I like this system so much I got another one. The last pic is an Aeroflo 30 which can also be modified to a 50.
The last pic shows 37 clones at about 3 weeks. I doubled up on a couple of pots. This system is a no-brainer. Just check your nutes and top off.
The 50 takes about 4 gallons per day. I don't even change the res solution as the soup is crystal. I will change to plain RO about 10 days before harvest. Aeroflo rocks.
