canna is great....ive been using their whole line for quite some time now...i use both rhizotonic and cannazyme together...because it says to in the feeding scheduale...but not when you are trying to establish roots....my personal formula for establishing root growth is 3-5 ml vega A&B with 30ml of rhizotonic to every gallon of water....the proof is in the pics...the first pic is well into flowering and the second pic is either 4th or 5th week of veg...remember these are in 5 gallon buckets.......not to bad eh...this is what makes me think canna speaks for itself...
