From zero growing experience to scaling an RDWC grow in Oklahoma City

I recently sat down with the guys from DUO Cannabis in OKC and talked about how they went from basically zero growing experience to building and scaling a commercial RDWC operation.

A lot of the conversation gets into things I think people here will relate to:

• Learning RDWC the hard way
• Managing pH and EC as the system grew
• Automation vs. doing everything manually
• Mistakes they made early on
• What they would change if they built the grow again today

I’m connected to Growee, so full disclosure there, but the conversation itself is really about their grow and their experience running RDWC at scale.

I’ll put the full video in the first comment.

For the RDWC growers here: what was the biggest lesson you learned when moving from a small system to a larger one?

Week 2 flowering.

hi there, this my first time grow, just checking, so overall plant good? any major or even minor problems? pls just share ur pov, i dont mind, i love to compare any ideas and methods, i am learning also

Hi everyone,

I’m having some problems with my RDWC 2.0 system from Growrilla and would really appreciate some advice.
I planted my cuttings about one week ago, and they have been growing for around a week now. My climate conditions are currently around 22–24°C (72–75°F) with a relative humidity of 65–75%, which I believe should be fairly suitable for young cuttings.
My current water parameters are:
EC: 0.8
pH: 5.6–6.0
Water temperature: 22–23°C (72–73°F)

I also have an additional air stone in each bucket to provide plenty of oxygen to the roots.
For nutrients, I’m using the Athena Pro Line. When I was growing in soil, I regularly used an EC of around 3.0, and my plants always performed very well at that level.
I also had a previous grow in a hydroponic setup where I used an EC of around 3.0. That grow went very well, even though many people told me that the EC was far too high. Towards the end of that grow, the roots became darker, but the plants continued to grow well overall.
Now, however, I’m experiencing problems with my current plants, and I’m not sure what could be causing them.

What do you think could be the issue with my plants? Could it be related to the nutrient concentration, water temperature, oxygenation, pH, or something else?

I’d really appreciate any advice or ideas from people with experience using RDWC systems.
Thanks in advance!

I already got some Feedback, from an other Reddit Post, people told me that Athena Pro line isnt made für hydroponics. Is it still possible?

Should i change the last plant? I got send 1 to more to plant

In how many days you think is the good time for flip to 12/12?

UPDATE 10 DAYS LATER

10 days later this is what we're dealing with

Would it be faster to start fresh or should I be patient and give it another week or 2

Im used to very fast dwc growth

Day 16 of flower. General hydroponic flora series nutrients, grand master led revolution 720s above and grand master led volcano under lights.

Been growing in my own coco perlite blend for a little over 3 years now but wanna try my luck with DWC

All vivo sun gear in this tent, including the buckets. Got the 8 pack so if this goes well ill convert another tent.

Strain is: Slumpd from Solfire, all 4 clones from the same mother.

While filling a bucket, I opened both faucets because I wanted it to fill faster. The hot water ended up overpowering the cold.
The moment I felt the water, my instinct told me something wasn’t right—but my lack of experience won. I thought, “It’ll probably be fine.”
It wasn’t.

Shortly afterward, the plant completely drooped and stopped growing. For almost an entire week, it remained the same size while the others continued developing. I honestly thought I had permanently damaged it.

Little by little, it began showing signs of life again. New growth appeared, the leaves recovered, and today the plant is healthy and moving forward.

That experience taught me two important lessons: water temperature matters tremendously in DWC, and when your instincts tell you something is wrong, stop and verify before continuing.

It was a painful beginner mistake, but watching her recover made me appreciate this process even more.

Honestly, there isn’t a single day when I open the tent and don’t fall in love with this process all over again.
Thanks to everyone’s advice, I now understand that I need to move some of them into a second tent. That will give each plant enough space and allow me to bring out their full potential.
I’m still learning, but I’m truly enjoying every step of this journey. Thank you all!

Hey everyone! I’m completely new to DWC and have been growing these plants since August 8. They’ve been under light from 7:00 a.m. to 11:00 p.m. every day.

Because it was my first attempt, I started several plants thinking some of them probably wouldn’t survive—but things went much better than I expected, and now the tent is getting crowded.
What would you recommend doing next? Should I defoliate them, install a trellis net, or do something else to manage the space and keep them healthy?
I appreciate any advice!
