You can't be that bad if you got 72 rooted bro.
What method are you using to clone? I used to suck at cloning. I was the worst.......then I made a DIY cloner from this thread. Now everything roots. EVERYTHING.
Good luck with the grow Joe.
im using jiffy peat pellets....i tried the aero cloner but i get better results in jiffys because the water in the cloner gets too hot....and aerocloners take up too much room.
