Hey Malo,
I have a thread elsewhere where I log all my grows although I've been a bit slow on updating it too. Google knows where. As for osrams, the ones you pointed out. Probably about 10% of total wattage, just to create a small 660 peak.
Yes, arduino with datalogger shield (which has a handy prototype area for resistors, transistors etc). Barely fits on a Uno in terms of connections and memory, ended up controlling all fans with one pwm (they all get roughly equally warm anyway).
BJB holders, tape (holders for now, not the cobs), cobs, and a digital temp sensor with more tape.
Some of the plants (hindu kush and panama clone) were already in transition for a few weeks, under an old 400watt mh on 4x4'. They've been under led for nearly 10 days now.
Panama
pure Hindu Kush (partly seeded, pollinated with PCK)
Panama x Silver Haze below. Both very stretchy yet high yielding varieties, vegged under 400w mh too low intensity for too long which caused them to stretch even more. Didn't feel like going to 600w hps for a week while I finished the brain. Fortunately I got 8 feet in height.
Yes, flat leaves. Only downside so far is that I have to turn my exhaust down too far to keep temps ideal which causes the humidity to raise a lot. That has a lot to do with my closet being unnecessary tall/large now an crappy high humidity outside though. Will fix that soon, the former that is.
My favorite, leaning more to afghanica parentage of silver haze in terms of structure, great for cropping too.
This run is mostly to check some crosses and includes a handful of males. I may use some clones of the best and do a quantity run after this one.
Most recent pic of the lcd I could find. I measured actual rpm of each fan at first but takes 4 extra wires and since I set the fan speed I already know how fast in % it runs, and they all run as fast. It's still a working in progress, still waiting on a few sensors (IR contact less temp sensor to calibrate the others, as well as measure average canopy temp). Sensor for humidity and ambient temp is hanging below the light at canopy level. The fans on the heat sink create an upward wind below the light skewing the results a little, need calibrate that. Values below are with light on 20% and just for minutes.
I use a remote like this one (an old TV remote would do too)
Dimmed to 30% or so:
