Thanks this is very helpful. what does the white areas mean (e.i. green is best, red is lockout white = ?)

more precisely, not 100% available.
I have to concur on lowering your ph @warjunkey. I also run rdwc systems, for perpetual grows. During Veg I like to keep my ph drifting between 5.9-6.1. To help with my Cal-mag uptake. When I flip to bloom I like to have my ph drift between 5.6-6.0. To help with my Phosphorus uptake.
If you keep your ph in that zone you won’t see any problems from deficiencies.
Thats what makes dwc so amazing. Having the ability to change your ph at any moment.
I use Advanced Nutrients Connoisseur ph perfect. But I still ph up and down, if I have to, to get that drift.
The other thing I love about dwc is being able to adjust the plants internal temperature with the temperature of the nutrient solution. You can really dial in the VPD.
This is one of my tents. The 4 plants in the back are female Royal Highness being LST, and the 2 in the front are males. They’re at Day 2 flower in that picture.
A couple plants rootmasses.
@Tygrow78 " being able to adjust the plants internal temperature with the temperature of the nutrient solution" can you explain this a bit. I am really new to hydro and have been having difficulties with the water temps
So when you have a good rootmass like my pics above, they will control your plants internal temperature. So if you have nutrient solution at 68f your plants leaves will be the same temperature. I can test that by using my temperature gun and pointing the laser on different fan leaves.
When you have that control you can zero in on how your plant feeds by its VPD. Thats done by adjusting the air temp, Rh, and temperature of the plants leaves.
I would encourage you to do a search of VPD on the internet. Their’s articles that can explain it a little better than me.
Dwc can be a little challenging, but when you get it down it’s an amazing way to grow.
It’s taken me 2 years to really get it down and dialed in. If you ever have any questions just let me know.
Awesome work cannafam!
I just watched a video and read a couple of articles on VPD…oww my head hurts!
