Nutri Plus is widely recognized as the most trusted hydroponic plant nutrient fertilizer in Eastern Canada for the past 20 years. This program includes a variety of unique and powerful foliar additives, the highest grade humic and fulvic acid available today and several super-charged bloom boosters in addition to the most concentrated, two-part, plant-specific recipe on the market.We recommend using 4 ml per gallon of the Grow A and B and 8 ml per gallon of the Bloom A and B, but they caution that less is more and all new users should start with a lower dose until they get a feel for what Nutri Plus can do for their plants. The base nutrients from Nutri Plus are made from reverse osmosis water assuring a reliable and quality product. By respecting rigorous manufacturing standards, their fertilizers contain fewer contaminants than the competitive brands. It is a fertilizer without electroconductivity that is chlorine free. The formula used in Grow/Bloom by Nutri-Plus is rich in calcium and magnesium, which are necessary for the production of healthy roots, the enhancement of the immune system and the production of chlorophyll.
