Video of my RDWC system I built since my old video link made my clip no longer viewable.

How did you post video?
Great idea!
I had thought of that as well, just hadn’t put it together. It sure is neat to find your idea.
Very Kool !!!

I have to put it on my YouTube channel and then copy the link from YouTube.

I didn’t know if there was another way
No I have tried so many ways. YouTube is the only one that works.
Have you tried an animated GIF file? Only good for short, low-resolution clips but they can be uploaded to this forum.

Those babies look NICE
That is GENIUS!
This is a simple Waterfarm type, single plant with remote reservoir, and feed back reservoir…This example has the drip ring is under the lid… 5-6 gal of water dripping from the dripring will keep the basket wet and add o2 to the water… But it can be configured a little differently and have the drip ring on top of the hydroton like a Waterfarm… The secret to the recirculating is a standing water column contained in a piece of 3/4" thin wall pvc…
The idea [the idea itself is hundreds of years old], lets you have the reservoir water available in the grow bucket… The pvc pipe is a couple inchs higher than the level in the grow bucket and the reservoir… As the water is pumped from the water column, gravity returns it to the reservoir…Don’t know how to preview these pics… Hope for the best…
Kicking this can a little further down the road… This time, a regular Waterfarm and the modifications to pump it’s own water from a remote reservoir… I use a free standing scrog screen… Here is another mod that adds a pass through for the water column… The biggest drawback with the mod that started this thread was that you couldn’t lift your girls skirt to check out her roots, and keep your hydroton balls in place at the same time… By drilling the exact hole size for ridges on the cone, it will snap in place like it was made for it… You need to cut 1/2-3/4" off the top of the cone…
I used the same hole location that GH put in the top bucket to drill the hole bigger… A round abs patch, larger than the hole to be drilled was contact glued over the hole on the inside of the bucket… It wouldn’t take the pressure when drilling the centering hole from the outside and peeled off… So i inverted the bucket over a 4"x 4" x12" pc of wood to support the patch while drilling from the outside…
I think this’ll be the last mod, probably the most needed. Picked up the drill at Harbor Freight… …
This is where I ordered the pass through… Speaker Cabinet Port Tube 1-1/8" ID x 6-1/2" L Flared

Here’s a couple pics of my modified WFs… No electric water pumps and no air stones… 26 oz total…
I used 1-315 watt cmh over ea plant… I used FloraNovabloom as my only fertilizer… The reservoir was a 5 gal bucket…

Got one more WF type grow, this one was to beat the summer heat… Just to show you what I mean by heat… This first pic was taken on a July afternoon… It’s a bucket with some insulation stuffed in it…
The screen can be raised by during the flowering period by lengthening the screen support pvc .
That’s about all i’ve got on WF type grows… Will be starting 2 igloo grows with a shared insulated ice chest reservoir… With no added heat from a submersible water pump and insulated lines, I think a single ice probe will keep the temp down… We’ll see… The yield was 6 oz, the screen was 18"x24"… My usual yield has averaged out to about 2 oz per sq foot of screen…

Do you have a build for these, intrigued 
I’ll be starting my Igloo grow soon, aka Waterloo I’ll start on the Waterloo build soon in the journal forum, unless it would be better done here? I find this site rather different than most, unless there is more I’m missing?
Have started on the ice chest mod with by installing a 50 watt peltier Ice Probe… I’ll get into more detail there… With insulation on the tubing, igloos and ice chest, I’m thinking the Ice Probe can keep pace to any added heat… Being a minimalist, I’ve dropped down to 315 watt cmh lights to save on power and did not hurt my yield… …
With out electric water pumps, and no air stones, I only have to deal with the ambient air temp, and the added heat from the dripring … With an air flow over the hydroton, imo, evaporation will remove some of that heat… I keep tinkering with the water airlift systems… Thumper, I’ll throw in a few pics of the unfinished modified ice chest…
The probe was bedded in spray urethane to secure it…, the blue tape was to keep the insulation off the rubber just in case I want to remove the unit…

im easy either way, just tag me if you move it,
ice probe interesting… why have I not heard of an ice probe…
, watching with interest…
Where can one source an ice probe and what are they typically used for…?

I bought mine off amazon, also bought a Ink Bird heat/cool temp regulator… It gives a better set temp range than the Ice probe temp controller… The probe is mostly used for aquarium temp. cooling…
