What about salt build up?
I use ProMix, coco will double my medium costs in my current setup.
But I want to get away from all that stuff , it’s dirty n gets every where .
Right now I’m thinking of using grow stones and rock wool croutons. And recycling the stone to cut the medium cost n mess .
You're trading off one set of possible problems for another, which can be a good thing if you think you can mitigate better against one set vs another.

I don't see salt buildup but I also run water only for the end week or so.

DTW requires that the amount of water to pass through the coco in order to reach the bottom roots and thus runoff is many times the quantity needed to water the same plants via bottom fed. I find you don't have to soak the whole coco medium when bottom feeding, the top roots go air and the bottom soaks up what it wants.

With DTW it's become obvious that overwatering is a problem for me in cooler temps. The plants do not use all that water. With bottom feeding the lowest roots don't dry out and the top of the rootzone can breathe.

I also find it way less hands on vs drain to waste.

My problem with Blumants is you need the res above them to create head pressure, when the level of the res drops the hydrostatic pressure drops , lots of adjusting . And I don’t have room for 4 res’ in the room at a good height.
They really don't need that much pressure as long as you keep your reservoir full-ish. My 27g reservoir is only about 2.5 feet up on a rack.

As for cleaning up run off. Can you dig up and seal a low spot you can put a small sump in it to pump out waste on a float switch?

There just isn’t room to fit 4 res’ in the room unless I get a table n put them under it.
I was playing with a 1/4 of the room with tables n different things . But the back wall suffers because I can’t get in there to clean up. Because I’m running CO2 DTW is the only thing that makes sense unless I want to add a big chiller , (I don’t)
Using a lot of power now.

If that fixes it I'd be curious how many amps are going through that line? Should be low voltage?
It is low voltage , it’s just a remote wire from the compressor to the head , they couldn’t get the right gauge so the doubled it up.
It didn’t fix it ,
I said this unit has to go.

After 5 troubleshoots and about 20man hours wasted plus , they finally agreed there’s is something majorly wrong .

How does bottom feeding coco perform in leaching excess salts, compared to DTW?
I use DTW and it's incredibly simple to set up, with timers, but it is incredibly wasteful, IMO.

@genuity - it's nice to see that the Cookies and Cream has been put to good use! I traded a giant Triangle pollinated bud of REBAR with EG for that pack.

Apparently PhotoBucket is broken so I can't load pics from there. I will need to try direct. That didn't work either. I was going to post pics of the REBAR seeded buds and the EG seed pack.

@BigHornBuds - can you put the res upstairs?


Cheers,
Mo

I’ve gave a few people real advice sometimes n they didn’t like it .
Here was my last attempt to help someone.
I might not of handled it professionally ,, but this is the Internet , I got a laugh.

That link took me down a rabbit hole of a clusterfuck of gmo definitions...lol. Why do intellects get so pissy with each other? It is entertaining. Do people actually smoke the buds they are growing now a days? Sheesh! 20 minutes of non mentally stimulating reading. Glad I was baked and can forget that part of my life.

edit* I see now BHB. lol. "skip". I'm sure that was a pantie buncher for him. I could've avoided the intellectual gmo debate had I started at page 2.
