Thanks
Using the Pulse I have managed to keep the environment dialed in pretty close to (what they say is) the "Best VPD" for each stage of the grow.
Currently I am in flower stage, and I am aiming for a tent environment of around
27 Deg C, at
52% Rh, this gives me an average
1.3 kPa VPD
Running 19 Hrs Lights on, 5 Hrs Lights off
Lights on Log - Last 16 Hrs Log
The Fan controller is keeping the tent environment within the target range, reasonably steady, very little movement.
According to all the available research, this ensures that the plants "Stoma" are operating at peak efficiency.
As you can see, It looks almost Spot On !

Of course, everything else needs to be dialed in as well....
My feed is:- Ph = 5.8, EC = 1.9, Soil Ph = 6.4
The Plants show no signs of any deficiencies, nutrient burn, lockouts, etc
Perfect feeding cycles of Wet/Dry (I love the Autopot system).
So, All things being equal, this should translate to maximum growth / yeild, etc.
To date, it all looks good.
I can recommend this bit of Kit
