Best Hydroponic Plant Nutrients for Stonewool Grow Media

Posted on September 8, 2020 by Red Rock Block

Different Types of Hydro Systems- 

There are six main types of hydroponic systems- Wick, Water Culture, Ebb and Flow, Drip Irrigation Systems, N.F.T. and Aeroponics. Out of the main common types of hydroponic systems, drip irrigation systems are probably one of the most utilized in commercial and industrial grow operations, and work great with stonewool grow media. #TrialandError 😉

What is a Fertigation, Dosing, or Plant Nutrient Delivery System?

big-ag-grow-opsA fertigation, dosing, or plant nutrient delivery system basically consists of different controllers, meters, valves, tubing, sprayers or emitters that work together to feed plant nutrients at different timed intervals.

In some cases, a commercial grow operation can directly implement a fertigation system, dosing system, or plant nutrient delivery system into their existing watering systems.

By integrating a high quality fertigation system a commercial or industrial grower can fine tune the mixtures and delivery of plant nutrients at specific times of the day or growth cycle.


Types of Hydroponic Plant Nutrients That Work Best with Stonewool Grow Blocks?

redflag-bloom-plant-nutrientsDeciding on which brand and type of plant nutrients will work best for a commercial grow operation typically comes down to preference, price, and performance. Some growers are stuck in their ways, while others understand the ever-evolving competitive landscape requires trying new products and systems. Using established and reputable plant nutrient manufacturer’s products is obviously a great place to start especially if it is a new grow operation. Some manufacturers produce both regular plant nutrients and hydroponic nutrients, while others only produce one or the other.

Some manufacturers may only create specific blends of plant nutrients while others provide an entire line of plant nutrients, plant additives, and plant supplements specifically for hydroponic growers. One good example of an established plant nutrient manufacturer that provides both regular and hydroponic formulations is RedFlag Blends. RedFlag Blends offers an extensive selection of regular and hydro nutrients for the veg and bloom stage, IronCalMag, pH up /pH down, BioSilica, and more!

Mixing Plant Nutrients and Batch Tanks-

mixing hydro-plant-nutrientsMost commercial and industrial grow operations usually have their batch tanks pre-mixed, loaded, and ready for delivery to plants and crops. Some growers prefer the dry form of water soluble plant nutrients, while other growers prefer to use liquid plant nutrients.

Depending on the growers personal preference, the type of hydroponic system, and the type of plants or crops being grown will directly contribute to deciding between water soluble nutrients or liquid plant nutrients. Click here to find out more about mixing and storing plant nutrients
