Any advice on the table? Really concerned about cleaning and possible slime in a large table that wouldn't be easy to get into.
Everything else seems to be buckets or coolers which is what I using for moms.
Id like to make an informed decision before dropping the cash on a couple of tables.
Thanks

An ebb & flow design? I have seen some use trays filled with hydrotron, you pump water up into tray from a reservoir and let it flow out, that would be the easiest way.
I think it would be tough to clean and keep light out, you would have to be able to have it elevated so you can drain it spray it out and then refill all without moving your reservoir.

I'm doing a system about that.
This is a 20 gallon cement mixing tub (Home de Pot).
On top of it is 1.75" thick sytrofoam with 3" holes cut in it.
There's two 250gph water pumps since side it. One for circulation and one heading to my 1/10hp Aqua Chiller.
I have a EcoAir 5 air pump with 8 airstones in it. This might be overkill, but the roots love it.
I've had various slime issues. I resolved them by lowering my res temps to 65f, adding Aqua Shield, and using Sub Culture B & M. The roots really love that setup.
Hope that helps!

Great DIY job on the table. I may reconsider my more expensive purchase of a system from the grow shop.
How deep is the tub?
Any additional info would be great.
Regardless I am going to run this all by my grow shop guy so he can make sure I am getting the correct stuff or equivelent product.
He is a DWC fan so I am sure he will help me out getting the right stuff.
I am very much a NooB but jumping in with both feet.
So far I am growing 4 mothers in individual buckets and although they are all looking quite healthy up top, down below they have all have the grey/brown slime to some degree.
1 SLH, 1 SSH, 2 PK.
Would you have an opinion on this solution to the keeping the slime away?

Many thanks for your reply.

Well if I can I want to stick with DWC. At least if I can control the slime.
Seen the vid. I may resort to Ebb and Flow.

The tub, which you get at Home De Pot for cheap, is 2'x3' and about a foot deep I think. I fill it with about 18 gallon of water (not to the brim obviously)
Here's a picture...don't mind the foam, I just added some Azamax which caused it to foam up due to all air I'm pumping in there with that EcoAir5.
This is what I do when I make a new 18gal DWC chilled res:
1. Sterilize equipment (soaking everything with 3% h202)
2. Add H20
4. Add Pyrosol
5. Add GH 3-part nutes
6. Add Aqua Shield
7. Add Hygrozyme
7. Add Super Thrive and Thrive Alive
8. Add Add Sub Culture B & M
9. Azamax (root aphid issue)

"Would you have an opinion on this solution to the keeping the slime away?"....you have two slimes. Root rot (pythium) and the brown slime algae.
Pictures 1&3 are root rot or pythium. Its the lighter brown slime. (rinse them off and water temps to 65f)
Picture 4 is brown slime algae (dark brown, sometimes chunky if you pull it off with your fingers).... and maybe a little root rot.....refer to some of Heisenberg's posts (a known user on here) for the slime algae.
The solutions for each slime can and should be used together. You'll be set after that.

i have grown in dwc tables for some time. i did them DIY from wood boards and geomembrane nylon, it's black intended to make outdoor ponds. i used pvc boards with holes as a lid. i used the same tables as flood/drain setup, just fill em with rocks in summers to prevent slime in high temps. in dwc you need very effective bubbling all over the water surface and you need to maintain water temps low around 68-70F. i also used H2O2
