Does Humboldt Nutrients Offer Free Samples?
There are 2 ways to get free samples of Humboldt Nutrients products. The first way is by going to, or attending a trade show that Humboldt Nutrients is showcasing at. We often bring samples of our products and other promotional swag to trade shows that we attend throughout the country during the year. Get to any exposition event early because samples usually go quick. Follow us on Facebook, Twitter, and Instagram for upcoming shows and any details. The other way you can get samples is retail store customer days around the country. There are retail hydroponic stores that carry our products, which often have customer appreciation days in which we will send one of our Humboldt Nutrients Brand Managers, or send a promotional package with samples if we cannot attend in person. Those are the only 2 ways in which a person can receive free samples of Humboldt Nutrients products.

What is PH?
PH is the measure of acidity or alkalinity of an aqueous solution. The term pH refers to the potential hydrogen/hydroxyl ion content of a solution. Solutions ionise into positive and negative ions. If a solution has more hydrogen (positive) ions than hydroxyl (negative) ions then it is acidic and has a pH in the range of 0 to 6.9. Alternatively, if a solution has more hydroxyl (negative) ions than hydrogen (positive) ions then it is alkaline with a pH in the range of 7.1 to 14. Pure water and deionised water has a balance of hydrogen (H+) and hydroxyl (OH-) ions, and is therefore pH neutral (pH 7).
A nightmare for many growers inside the hydroponic industry is the fact that pH adjustments need to be made frequently to nutrient solutions. In fact, people often adjust the pH of their nutrient solutions daily in an effort to keep the values close to those considered ideal. When daily adjustments are needed many growers often opt for an automated system for PH control.
Things that affect PH fluctuation are dissolved oxygen in nutrient solution and amount of aeration added to nutrient reservoirs, nutrient uptake by plants, and the air outside nutrient solution reservoirs and hydroponic grow systems. The recommended pH level for a general hydroponic solution is between pH 5.8 and pH 6.5.
* Many other variables can affect the pH level as well including:
o Air Temperature
o Amount of light
o Water Evaporation
o Tap water refining
o Amount of nutrients
With this amount of variables, periodically(daily) checking the pH level of the solution is vital to maintain a healthy environment for the growth of the plant.
Adjusting the pH level of the nutrient solution can be done simply, with chemical(phosphoric acid for down, potassium hydroxide for up) or natural buffering agents(vinegar for down, baking soda for up). As a general rule standing water and nutrient solutions will gradually increase in PH over time, so PH down buffering agents are used more frequently to keep in proper range. The internet and the library are great resources for learning more about why nutrient solutions and water PH fluctuate.
