Single Waterfall RDWC Tote: Critique My Idea!

• 27 or 38 gallon hdx tote (yellow/black).
• Eliminate the air stones by using an external dc marine pump to suck the resevoir water out of the bottom and pump it back in at the top (pvc with a slit cut for a water curtain?)
• 3 net pot nodes and a fourth hole for maintenance.access
• Cover all holes with plates for light leak
• Potential idea: pump on a timer 3x per day for 5 minutes, drip irrigation {good or bad idea?}
• Question: do Peltier coolers work at all?

Hey all,

New to hydroponics. I'm an avid soil grower and the closest to hydro I've gotten is hempy buckets. However, I like new things and am interested in giving DWC a shot.. (I'd like ebb & flow but I have height restrictions). My idea is this:

Ebb n flow is doable with only using like 14-15". Similar to a buckets height.

I have never used this product but for small systems it could be nice. They say it cools their 27gallons 10 degrees. Who knows..try it and lemme know how it goes

Cheaper on Amazon.
It's branded as Ice Probe.
They have weird controllers though... But VaderVision YouTube channel just built a micro Rdwc system with only like 5 gals using an ice probe and its more than efficient.
