I have just started growing my babies in miracle grow from the advice of a friend. Personally I think it is the biggest waste of time ever. After a week of 18 on 6 off there had been no change whatsoever in the size of them. I have now had to take the drastic action of re potting in canna professional when I took the babies out of there pot there were no roots at all coming out of the jiffys and its not the plants as they have come from different sources but with same results. Hopefully my babys will recover but I strongly advice anyone who is thinking of using miracle grow to stay well away!!!!!!!!
