I am only familiar with Celcius, so go and Google a conversion calculator for the temps that I mention.
Water Temp:
You will want to run whatever style of Water Cloner (mine happens to be a bubble cloner with pool noodle inserts) between 24-28 Celcius
At higher temps the cuttings will root faster, but increase your risk of algae and root rot.
At lower temperatures, obviously your cuttings will root slower.
Pending on how cold or hot your winters and summers are, temps can be adjusted by a 25watt aquarium heater to bring the temps up, and if you want to lower your temps, freeze a 600mL PET Coke bottle of water and place in your water bath (keep a couple frozen to swap around)
****Just a quick note, buy one of those cheap ass digital aquarium thermostats on eBay and use that to monitor your water temps.
Air Temp:
20 - 30 Celcius is ideal.
Lighting:
Clones don't require massive amount of light like mature plants, as their energy is focusing on building roots. 10 watts per square foot is sufficient.
Nutes:
Only water is sufficient as their are no roots to soak up the nutes. This doesn't mean you can't add a weak grow or rhizome nute to the water to be there for when the first roots appear and have their food ready. But, at end of the day you only really need water until roots appear, and then you want a very weak strength grow/vegging nute to start with.
BTW, that's a ripper cloner you have there. I, myself use a bubble cloner made from plastic tub, cut pool noodle, aquarium heater, digi thermostat and dual outlet aquarium air pump, and keep them under red and blue LED panels. Oh and almost forgot, I painted shit loads of black paint on the plastic tub to reduce the light to prevent algae growth.
