I love the mist king set-up.
I suggest you start with the advanced system. While you're at it, choose the option to go with the 3/8 inch tubing, and the RCT-24. ($6 more) This timer allows you to set the (diaphragm) pump on the repeat cycles that your aero system would need to be supported properly.
Along with this, you may want to find a different sprayer on eBay, or Amazon ( search for "black plastic 3gph nozzles w/poly filter push tee 3/8 - $90 for 10. The sprayer nozzles that come with the advanced mist king system are a bit large, and in the way of the roots as the develop ($200 less if you opt out on the Mist king nozzles)
I love this system! My plants love it as well. Try what works best for you.
My Blue widow are 18 days old from seed, and munching up nutes at 1/7 min spray intervals.
The set-up in the picture is w 1/2 inch. I will be expanding with Fogponics very soon.
So speaking from my limited experience, do as I should have done and get the correct system first.
The half inch lines are way too narrow (!!clogging issues!!) for any high ppms and also allows for the higher pressure on regular intervals. It sounds as if you're building your system as well. This is a great idea! No-one knows better how to service and troubleshoot than the one who constructed it.
Advanced system to my spec should be in here in two days. If there is any interest, I can keep you posted.
I wish you the best of luck/experiences with your grow. Keep us posted!
