the aerocloner shootout seems to have run across a seasonal problem. The temp in Canberra has been 38C (100F) & the cloners have been getting warmer than I would like. I think I should leave them both in the same window as the earlier trial, until I get clear evidence that it is working against getting a result. So far the increased temperature in the air stone rig appears to have delayed the setting of roots by 1 day, & reduced the number of roots set by around 35%. It is running at 26C most of the time. The ultrasonic transducer rig is consistently running 10C hotter than the air stone rig, It has reduced the number of roots set by 85%. One plant has died & rotted (or vice versa). I will let this test run to its conclusion on boxing day, but I think the evidence so far is that ultrasonic transducers really have more of a place in a cold climate winter application, where the heat from the transducer can work in your favour, rather than during summer & hot weather Related PostsCheap Ultrasonic Aeroponic / Hydroponic How-ToIndoor Hydroponic Spinach Update – S2 Episode SomethingLow pressure aeroponic system version 2 – Progress update #1Air Stone Setup for Hydroponic Growing – Oxygen Is Plant FoodMittleider Garden Update: Albert & Irene’s Fall GardenAir Stone versus AIT Air Injection Technology for Hydroponic Systems
