Kelp contains many plant hormones and nutrients that make for super healthy plants.  Two time world record holder Ron Wallace once said if there were only two things he could put into his pumpkin patch, that kelp would be one of them.  RAW Kelp is 99% Kelp extract from seaweed (Ascophyllum Nodosum). This product is water Soluble and contains only 1% soluble potash which is a direct reflection of its purity.  Kelp extracts are also very rich in natural plant growth hormones. RAW Kelp is a beneficial supplement to all feeding schedules. It is also ideal for adding to foliar sprays and for creating optimal recipe solutions.  Try mixing kelp with humic acid to find even greater results.  A little goes a long way.  This 2oz packet can make up to 200 gallons.
