Bloom PK is a cost effective substitute for Canna PK 13/14 or House and Garden Top Booster. The 300ml bottle is larger and cheaper, and the 2.5L bottle is a great substitute for a Canna PK13/14 1L or 5L bottle. Why do we recommend it? We've tested it. NPK: 0-19.5-21  (Ratio is almost identical to other leading brands).
