Hi toemato, Looking good! I am giving the Super Closet's Superponics 8 a big thumbs down. I have been using the res water pump to empty the res. If you turn the res water pump on and open the valve on the large hose that comes out of the top of the unit the pump will drain most of the nute solution from the res. I watch for a reduction in flow and the level of the res to shut the pump off when the level of the res get low as to not burn up the pump. After the res is mostly empty. I refill it without worrying about the small amount of liquid that's left. So far so good. I did however purchase a Stealth Hydro Drain Kit, or bulkhead valve (see:

http://www.amazon.com/gp/product/B00FCKR5EC/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1) My plants are drinking a gallon a day and there are about a gallon of roots so the plants are drinking half of the res solution everyday and subsequently the PPM are all over the place.
My dealings with Super Closet have been fine except that when I received the unit they shipped me a box with someone from Illinois paperwork. Hopefullly whoever got my name and address in their shipment is cool. After receiving the unit and opening it up I had to call Super Closet several times to figure out how to use it. Super Closet is so stealthy they don't have a users manual. They answered all of my questions but for the premium they extract from you for their fool proof system it seems shoddy. Finally, although it's not needed the top feed system on my unit has shut down and I won't damage the plants by trying to dig through the roots to fix it. Anyway I am not trying to hijack your thread. Keep up the nice work on the grow. I've got to build myself a SCROG net like yours.
