Hey Fam,
I have been working on a variety of setups over the years and I am close to my finish line in my flower room.. just looking to bounce ideas around looking for positive feedback as well as playing devil's advocate for room to grow as there are always better ideas out there:

• Separate epicenters + separate reservoirs
• 2” return plumbing
• Adjustable bucket spacing between cycles
• Dedicated trellis bulk lane

Left Lane → Mid / Late Flower (bulk phase)
Right Lane → Early Flower (stretch phase)

Independent EC curves per lane.
No shared nutrient solution.

Root Zone Control

• Dual water chillers (one per lane)
• Root zone maintained 64–66°F
• Blue Diamond 60 air delivery
• AL-60 air delivery
• 200 GPD RO system
• Sterile root protocol (PAA)

High dissolved oxygen.
Clean uptake.
Stable root environment.

How is the system running? How do you like it?

I am loving the system I've been using this system for a good eight maybe 10 years. When I did soil in the beginning I was guilty of overwatering etc and I just fell in love with hydro and it made sense to me so I create all these systems for people and really enjoy it. The outcomes are great when you really get to understand the water and realize that Less is more in RDWC. The hardest part I believe is learning to read the plants over the years not learning how to read labels on the bottle. If you follow bottle recipes you're always in the highest area of danger to hurt the plant. Like for example I use Athena pro if I was to actually use their listing I would be in a 3.0 plus EC range so I listen to the plant I use core until I get to about .8 EC then depending on the situation I go from there like for grow I will maybe add 20 g to the system that's it 10 lb box with me lasts a year..but here is an update pic you can check out. Let me know if you have any questions ty

Sweet looking rig ya got going here. Awesome setup for a hydro guy. This is gonna be a blast to watch.

Yeah man, reading plants is the answer. Them bottles will lie to ya and I totally agree with less is more. Thats a real hard concept for some to grasp.

Usually because growing takes a little patience and thats not a trait all have an abundance of..lol Most want it and want it now. We measure progression a week at a time not in a minute...lol

Man did you nail it especially for me forthcoming here I'm in recovery like if I drink alcohol I break out and handcuffs and cocaine lol so I'm 420 California sober we call it here and have been for over a decade thank God so I can definitely understand the saying I want what I want and I want it right now so this is definitely help me learn the patience in life. And thank you so much My veg tent is pretty close to this too but I just use four site lids to pump out more and veg without taking more space thanks for the good feedback.

Love your clean orderly approach to all this. You can see you been riding this hydro horse a while. It is an outstanding method of growing with growth speed that blows ya away. When I learned to grow it was with bubbler tubs in a basement.

Today ima lazy ass salt grower. Slowed things down a lot when i returned to growing. Its like going from a constantly casting bass fisherman to a drunk ass cat fisherman sitting on the bank waiting for a bite..lol
