Growth Science Nutrients was formed in Santa Cruz, California in 2013. With Santa Cruz being a very popular spot for growers, it was a no brainer to build the companies main base. The company prides itself in making nutrients widely available to farmers and most importantly, affordability. Their company motto says it all – “Deep in the mountains of Santa Cruz, California, a team of plant enthusiasts set out to create high-quality plant nutrients with visionary thinking and scientific process that goal was achieved. Growth Science Nutrients is designed to help your plants reach their highest potential.”
Their veg booster Solid Start provides extra nitrogen and potassium for having the best NPK ratio in the veg phase and also includes all the boosters and additives required to enhance root density and encourage rich growth. Also they offer Rock Solid, which is a flower additive containing three products in one, among them a PK booster, terpene enhancer, and bloom booster. And finally they offer Strength, a silica product. Growth Science Nutrients realized that the industry did not have an organic fertilizer alternative on the market that satisfies three key objectives. The first one is being truly organic because several companies skirt the certified organic standards by using the word organics to sell more, becoming that word a loophole. For that reason their line will be OMRI and CFDA certified for usage on organic crops.
Second, as most of the components in most organic fertilizers are not in a form readily plant-available, lots of growers use helpful inoculants and teas in order to accelerate the process of making those components available. Growth Science Nutrients plan to create a 100 percent plant-available line.
Nutrients Needed For Cannabis
The proper nutrients for cannabis in the right proportions can have a significant impact on the quality and volume of your bud. There are many factors that affect your decision when selecting the appropriate nutrients for your crops, among them, growing in hydroponics or soil, your budget, your expertise, and the amount of time and effort you want to put into modifying your system. Furthermore, you should bear in mind that there are some important differences between soil and hydro nutrients that must be understood before buying your fertilizer. The most essential aspects to consider when buying concentrated nutrients are that they have the right NPK ratio, they are intended specifically for hydro or soil growing, they have enough micro and macronutrients and the nutrients are chelated, or coupled with an organic molecule to make them absorbable by your plants’ roots.
When looking for cannabis nutrients, you’ll see a lot of info about their NPK(nitrogen, phosphorus, and potassium). They are the three most significant nutrients for all plant life. Getting the right balance of these nutrients during each stage of the cannabis plants’ growth cycle is crucial for obtaining top-quality yields and buds.
Both phases of cannabis growth, vegetative and flowering need different NPK levels, as can be seen below.
Vegetative: high nitrogen, medium/ high phosphorus, high potassium
Flowering: low nitrogen, high phosphorus, high potassium
Hydroponic nutrients are composed of other essential minerals and micronutrients among them, magnesium, calcium, iron, sulfur, boron, cobalt, copper, manganese, molybdenum and zinc.back to menu ↑
Soil vs hydroponic nutrients
Before buying nutrients, you should make sure that they are specifically designed for soil or hydroponics, depending on your grow setup. In soil, microbes contribute to the transformation of organic material like guano, worm castings, and many others into usable nutrients for your plants, but in hydroponics, you should provide your plants with micro and macronutrients.
Soil nutrients have higher phosphorus levels, lower nitrogen levels, and are completely organic instead of chelated.back to menu ↑
PH and electrical conductivity in hydroponics
When growing hydroponically, you must regulate both PH levels and the Electrical Conductivity(EC) of your system as well as buy nutrients. PH is significantly vital now that the wrong PH either too acidic or too basic, limits your plants from absorbing the full quantity of nutrients they need to thrive, meaning that you must spend a lot more money on nutrients and as a consequence your plants will suffer, diminishing your yields.
Cannabis always needs a pH level between 5.5 and 6.5 and you may manually adjust the pH of your nutrient using a pH tester.
With a pH tester you can manually adjust the pH of your nutrient solution or you can simply get a pH dosing tool that does it for you.back to menu ↑
