Check out j232s build. Fragileassassin and I walked him through his whole setup.
So am I understanding this correctly? You're using 3/4" PVC for the feed and return and reducing the feed to 1/2" to increase the pressure from the manifold?
Yes but 2" returns.
Ok, I'll need to find a source for the 2" bulk heads. I didn't see those on Home Depot's site.

I didn’t reduce to 1/2” anywhere on my manifolds but you will want to.

Yeah, I saw the comments and thought that's what you meant. Thanks!
That's what I'm going with. I think just for the experiment I'm going to buy two of them. One for the plants and one for the reservoir. Then I can easily add another later. I see most of you are using a chiller. I don't think I'll go to that expense. My plan is, I have a freezer sitting just outside my grow room. So I'll freeze some half gallon jugs of water, and every morning when I go open the doors, I'll drop a jug in the reservoir. This is just an experiment for me, so we'll see how that works.
i think 10 days is about max. but some people do nute top-offs and only do a few changes per grow.
Yeah, I guess I'll have to see how this goes. I did some calculations and for just the small setup I'm doing for two plants would require about 40 gallons of nutrients. It seems like a waste to dump 40 gallons every couple of weeks. I'm currently using Maxibloom, so I'd go through a bag of that pretty quickly changing it out that often.
I think Lucas is stupid. just use the gro too. Frozen bottles will become a nightmare for you.
I have it figured out that I can add back 7 gallons with 50ml calmagic, 50micro 100b for a no gain in ppm. As in now I can go 8-10 days before I would need to change over. I couldn’t go more without problems based on my experiences up to this point.
I went back to Lucas, the plants didn’t do anything different with grow for my 2 week tryout. I’m interested in seeing if I can make it threw flower on it. If I’m not impressed I’m going with jacks for a try. I think Lucas will always keep a plant happy but if you lose you mojo on it, your fucked.
Veg tends to be very forgiving with this, as long as things stay stable you can pretty much just do full strength nutrient top offs for a month long veg. too much longer than that Ill change once in the middle.
Are you using the slip inlet and slip outlet version of the 2" bulkhead? And I see they have a screen for it. Are you using any kind of screen to keep any roots out of the reservoir?
