Yes indeed it works. I have ran it for 2 "cycles". First run I had 5 of 7 grow roots, second run I only filled 5 holes and 3 grew roots. So basically67% success rate. I believe one reason the others didn't take is I didn't flush the soil out before taking the cutting. I'm not sure if it's absolutely necessary but I read that for the 5 days before you plan on cutting you're supposed to water 2 gallons of water per 5 gallons of soil to flush the soil of any fertilizer. Reason being is that if the cutting already hasnutrients in it, it has no reason to grow roots to receive nutrients. I also had to fiddle with the light levels....too much light and the cutting will focus too much of it's energy on photosynthesis and not rooting, too low and it can't make any food so I had to find that balance.
