I’ve had a good look over all of your figures and believe it or not, after I got some humidity into the tent, I’m running close to you. Main differences are I’m not gassing through veg, I’m not using R.O, and I don’t use calmag. If there is a significant improvement, I could easily make this happen but is it really worth it?
Why do you back off nutes during the bulk?
As for your set up... Amazing!
Mine isn’t as dialled in as yours, as I have separate controllers doing individual things.
Can you dial in VPD at room temp with the IntelliClimate?
Is there separate set points for night/day for all parameters?
What rh/temp equipment do you use? AC and a humidifier?
I prefer to use RO as it gives a clean slate to work with, no crap or chlorine/ chloramine etc.., knowing exactly what makes up the nute solution, and in what ratios, I use beneficials aswell. My water quality varies heaps throughout the year also. Surprised you’ve not had cal or mag issues in coco and haven’t had to supplement at some time.
During the last few weeks the majority of new growth formation has stopped or really slowed, only to leave flower bulking. I’ve found 1.6EC is enough for that. Why waste expensive nutes, and risk over feeding and causing issues that could actually inhibit bulking.
Cheers, I put a pic up for a bit from early in this last run. It’s been posted before and most of the regulars here would have seen it so I pulled it down. Think the boys would like to see your setup.
I used to run separate controllers...PIA, things would fight against each other, difficult to get offsets right, no real intelligence, and couldn’t have seperate day night settings. I bit the bullet and laid down the $’s when I built the new sealed room and got a proper grow room controller.
There’s a heap of features on the Intelliclimate that I don’t use, like growth stage and scheduling. I just change settings as I go, and reference a VPD chart (the one I posted for you) if I have a brain fart and forget the VPD I’m wanting, or need to change it based on LST.
Yes, there’s seperate targets for day and night settings.
I’ve got 2x 5 disk fan forced humidifiers that I made. A quest 70 dehu. 3.5kW split system AC. A large (non fan forced) panel heater. All the intake and exhaust fans. co2. Lights. All connected into the controller.
