Well put.
Analog = large dead band
Fuzzy = hysteresis
Chucking hot rocks, or any foreign heat source in a fuzzy logic controlled oven will cause it's predictive abilities to go haywire.
How did you quantify this usage, kill a watt? Seems low, but I'm not used to smaller ops.
Probably about the same monthly cost, but sans the expense and complication of the chiller.
I've done both, was a chiller guy only for well over 10 years but a round of testing benificial bacteria...
I run dwc and use no chiller. Instead I find it more cost effective and simpler to use a benificial bacteria tea. Good bacteria eating the bad ones works well and plants thrive.
Harvest time is best determined by watching trichomes for color change.
Take harvest wet weight x 0.25 to guesstimate dry weight.
Not growing, probably too late to salvage much yield.
