Dutch Pro are fast becoming one of the most popular nutrients on the market today. This is because growers the world over are finally finding out the secret of professional Dutch growers for themselves. After 30 years of producing some of the finest plant nutrients, Dutch Pro are at last getting the recognition they deserve in countries other than just Holland. Dutch Pro Auto Flowering Grow Hydro/Coco A&B for Hard Water is a 2-part nutrient for use with all Auto Flowering plants grown in a hydroponic set-up or Coco while they are in the vegetative growth cycle in hard water areas. Dutch Pro produces some of the fastest, healthy growing plants that you'll find anywhere, and the fact that they have spent the money on what's inside the bottle rather than on fancy packaging means that they're great value-for-money too. It’s no wonder that Dutch Pro are becoming so popular!

This is an almost unique nutrient because it is specifically designed for Auto Flowering plants which are becoming ever more popular. We don't know of any other nutrient that is made just for this special type of plant. If you want your Auto Flowering plants to reach their full potential, you have to give this Dutch Pro Auto Flowering nutrient a go!

Dutch Pro Auto Flowering Grow Hydro/Coco A&B is a 2-part nutrient especially for use in the vegetative cycle. The Hard Water version has been optimised for use in hard water areas. Dutch Pro Auto Flowering Grow Hydro/Coco is formulated to work perfectly with Auto Flowering plants grown in hydroponic set-ups and Coco. Auto Flowering plants have different nutritional requirements because their growing cycle is short. This means that to get the most out of your plants, every day that they are in the vegetative cycle must be taken full advantage of. Dutch Pro Auto Flowering Grow Hydro/Coco contains a sophisticated blend of ingredients to provide all the basic macro and micro nutrients that plants need for strong, healthy growth in the run up to a successful bloom phase. 

Dutch Pro particularly recommend the use of their Multi Total, Take Root and Keep It Clean with this nutrient. Dutch Pro also produce their own pH down for Grow product, based on nitric acid rather than the usual phosphoric acid. This is because nitric acid works better in the growth stages. 


Fill your Coco feed water container or hydroponics reservoir with water and add equal amounts of Dutch Pro Auto Flowering Grow for Hydro/Coco Part A and Dutch Pro Auto Flowering Grow for Hydro/Coco Part B to the container to achieve the required strength and mix well. Dutch Pro recommend a dosage of 2.5 to 3.5 ml/Ltr of both part A and part B. Dutch Pro recommend using a syringe or beaker for accurate measurement of this product and a CF/EC/PPM meter such as the Bluelab Truncheon to check the TDS. Adjust as necessary. Next, add any additives and boosters you wish to use and again mix well. Adjust the pH of the solution to the required level using pH up or down as necessary. Dutch Pro suggest an optimum pH of between 5.8 and 6.5 for best results. We recommend the use of a pH meter such as the Horticare pH meter to help accurately set the pH to the required level.

Both parts of a 2-part nutrient are designed to be used together in equal amounts. Using only part A or part B, or using them in unequal amounts will result in a nutrient solution which is not properly balanced. This will almost certainly lead to your plants suffering from deficiencies.

As with all nutrients, boosters and additives, never mix them together in their concentrated form (i.e. straight out of the bottle). Always add each nutrient, booster or additive to your reservoir or feed water in turn, giving the solution a good stir to mix it in before adding the next one.

Auto Flowering Grow - Hydro/Coco A&B - Hard Water recommended dosage: 2.5 - 3.5ml/Ltr of both Parts A & B

Auto Flowering Grow - Hydro/Coco A&B - Hard Water recommended pH range: 5.8
