100gpd RO
44gal ro reservoir
34gal nutrient reservoir (temp regulated)
2x4gal accumulators ("temp regulated" pseudo)
total nutrient volume in the system approximately 44gal
1/10hp chiller
48 site turbokloner (temp regulated)
2'x4'x5' veg tent w/ 560w (10x cree cxb3590 3500k) light
16" wall mount hurricane, sometimes a floor fan. 6" hyperfan and carbon filter
4'x4'x7' flower tent w/ 560w (10x cree cxb3590 3500k) light
16" wall mount hurricane, always a floor fan, 6" ac infinity (great fan, very quiet) and carbon filter
an environmental controller that I built
a reservoir controller that I built
system pressure is 80-120psi, 125psi safety relief
I use cdp 8852 pumps to pressurize, and a seaflo pump to recover.
I strain to 40 micron pre pump, and filter to 1 micron.
Drying:
I dry in a closet, that I use for storage when I am not drying. It's sealed off, and temp/humidity controlled.
60%rH +/- 1%
70f
Medium:
no medium (root trellis?)
Bucket-in-bucket
5 gallon buckets
the lid has the plumbing, 3 3/4gph misters and a 12v nc solenoid valve
top bucket has a bunch of small holes to allow it to drain, and I also put a nylon "mesh paint strainer" in it to give the roots something to grab onto.
the mesh also helps stop the nutrient mist droplets from coalescing onto roots, instead of bouncing off of the walls and onto the roots the mesh catches them.
the bottom bucket is insulated on the exterior, and has plumbing that gets hooked to the recovery pump
System targets are:
60%rh +/- 2%
78f +/- 2f
I monitor CO2, but don't supplement, I make enough medicine without it.
1.2-1.6EC
res temp 68f
5.7-5.9pH
perform addback at 1/4 initial strength 1x daily res is topped off
I change it out after the EC drops below a threshold.
The accumulators are bled back into the reservoir every hour, this ensures the nutrient solution is constantly conditioned and filtered. (and more homogeneous)
Cloner:
0.6EC
5.7-5.8pH
72-74f
I use a blulab guardian in the cloner when it's running (my second monitor usually)
Nutrients:
20ml protekt at change to buffer the RO water
186-200g greenleaf mega crop (old formula)
75ml hydroguard
50ml emerald harvest calmag
splash of mammoth p
addback:
mega crop concentrate
How do I have different environments in the same room? By manufacturing air (70f 40%rh) outside the tents and manipulating extraction to achieve system targets.
System behavior:
Very complicated, makes a lot of decisions to try and keep the environment "nominal". It can let me know if there's a problem even if I am not home, and I can change things or shut it down remotely.
I change the reservoir, clean, prune, perform normal maintenance and calibration. That's it. About 10 minutes a day to hand water moms if I don't have any chores.
Building it wasn't particularly difficult but did require a lot of planning and time. I had to teach myself how to program and do several other things to make it happen.
