2 didn't survive sprout stage. Now I have plants P1 to P1d. Using HERB.IQ to track the
grow. You can't improve if you don't have the data. Plants P1 and P1a occupy the same 7 gallon
smart pot, 1b,c, and d are potted individually.
They live in a Hoffman Proline modular enclosure, interior dimensions 23.62" x 23.62" x 78.74"
I have a pair of them, leftovers from other projects, as is most of this current project.
Math has always been a struggle for me. To compensate I started with a over build the shit out
of it to beat the heat, thought process.
Illumination started with 4 of these CXA3070-0000-000N00Z450Fs powered by a
HLG-185H-C1050b. They are mounted on an aluminum plate 9'' x 23" x .5".
On top of that I attached 9 heat sinks out of Dell computers, decent thickness for the copper
contact plate, 3 heat pipes and they weigh just under a pound.
Now add 5 fans and you have light number 1.
I had planned a 2 of these, one using 8 3070s
in two strings to veg and another one using 6 3590-0000-000R00BB30Fs in three strings to
flower, well that was the plan.
Drilled the plate for the Ideal COB holders. Didn't bother with tapping, used stainless steel
torx screws salvaged from trashed hard drives. They threaded right in. I felt it was an
acceptable compromise after watching the video of how to use them, 2.4 - 4.5 in-lb of torque is
very little.
Unfortunately the wiring part of light build was a disaster. I could only get one of the
strings of to 3070s to fire consistently. The other string kept flickering.
Everything I read said that's a sure recipe for wrecking COBs and power supplies so I
shut it down and pulled all the components so I could check them individually.
