I have been cloning for 7 years and I have tried everything you can imagine. Everything from home made willow water to root accelerator. Its all bullshit all I use now is plain ole tap water chlorine and all changed out every 7 days. PH not needed. Dont over think it its that easy.
Water vs root accelerator.....wait for it.......water won money gone wtf.
I learned something when I moved out to the country suddenly all my clones were dyeing and I went from 100% to 50% over night and that went on for almost 2 years.
Then I moved back in town I was back to 100% it took me awhile to finger it out. Turns out in the country I was on well water and pathogens would eat me alive in less the 3 days. It was the chlorine in the water that was saving me go figure
. I was always taught to get rid of chlorine. Ez clone company started pedaling this stuff called clear rez which is nothing more then pool shock for an outrageous small fortune.
Here is a link from our own roll it up laying down some truth.

Long story short use plain water unless you live in the woods then use some pool shock. After you see roots use some bloom nutrients at about 300 ppm and go from there. Good luck bro. Here is a link to my cheap bubble cloner if ya wanna take a look.

I guess ez clone didn't make enough money on us with a 400 dollar unit they want to sell you .04 worth of pool shock for 20 dollars. I think that takes the cake on rip offs if you ask me!!!!!!!!!!!!!!!!!!!
