I'm going to use my own 5gal buckets. I'm going to build my own system. I found buckets for a 1$ each and the 50gal drums for 10$ each and 2$ for the 10" net pots. I may even have to dissemble the flow and control and reassemble it in a tote if I can't keep the water level where I want. I'll make it work to my needs.
You use the Titan? I'm going with the C.A.P system. It looks like I can flood and drain as many times and as long as I want. My drum/reservoir will be on the outside of the grow area.
You think I will have more heat issues than you when your buckets are empty? Air warms much quicker than H2o brother. Stick a temp probe in one of your buckets and monitor the temp whet there's no water in them. I promise you it will be more than when the water is left and then drained and recirculated back. That is what I was trying to get at with your system and your RR issues, By the way how is the RR going?
Alaskan. Think of it like this. A car in the summer heat sitting in the sun. (same as ya plants buckets) windows up and not much of a breeze. Heats up pretty quick. Now fill that car with H2o and leave it out there. the temp will still rise but no where as quick. It will work and better. Your roots are on the bottom of the bucket baking in the summer heat of your tent brother. I will fix this in my grow.
Think of this... if you dial your tents in correctly, you won't need to try to make water in a bucket cool a tent, which doesn't usually work, by the way, unless it's got a fan blowing through a cloth that is wicking up the water. Quite the opposite in fact, your over heated tent will heat the small volume of water in the buckets and you can pythium your plants bubye....
And you telling him that his tents are too hot and he's baking his plants is . . .um . . . uninformed... His tents are pretty well dialed in and he's running three of them. The root rot is long gone...Been gone for quite some time.
