I know that the question was not for me and most ppl don't consider my opinions but here it is:
BN SPRAYMIX - BN Spraymix is a pure biological and non-toxic care product and consists of a special combination of sea-algae and organic extracts. This product consists of auxine, sea-algae, chelated calcium, vitamins, amino acids, 80 trace elements, natural fatty-acids and a great number of natural growing and flowering hormones.
The special combination of these components makes for a better metabolism, a better budding of eyes and shoots and a higher chlorophyll production, (this is of great importance for cultivating with artficial lightning). This is especially an important product for mother plants and cuttings. In case of mother plants, BN Spraymix makes for more shoots and consequently more cuttings. In case of cuttings, spraying with this product makes for vitality and long-lasting green cuttings.
Humic Acid is also good stuff but Fulvic Acid makes all the difference. The two together are tha bomb. What i use is BN X-Cel (Humic) and BN TML (Fulvic). No overdose. You can put what you want. More dosage, bigger nute absorption.
