Zinc in Aquaponics

Zinc is Great in Small Quantities Zinc is a plant micro-nutrient – which means that it’s only needed in small quantities - but don’t be mistaken; Zinc, as an  important component of many plant enzymes, is crucial to plant growth. Without enough zinc, these enzymes can’t be produced and many essential plant functions slow down or stop altogether, which stunts the plant. Excess Zinc Is Dangerous To Fish Because zinc is...

Sulfur in Aquaponics

Sulfur is one of the secondary macronutrients and is very important to plant production.  In aquaponic systems sulfur is rarely deficient.  It’s one of the reasons you hear about it so often.  In fact, sulfur is more often present in larger-than-necessary quantities, primarily because we love to use supplements that are sulfate based. SO42-  Sulfur occurs in solution as sulfate, SO42-, a soluble anion.  Sulfate is taken up directly by...

Magnesium in Aquaponics

The Importance of Magnesium in Aquaponic Systems Magnesium is a very important plant nutrient and is up with Potassium when it comes to common plant deficiencies in aquaponic systems. Magnesium is an important part of enzymes, proteins and the machinery of photosynthesis, and when it’s deficient, it can really impact the productivity of your system. Magnesium is one of the plant nutrients that interacts with potassium and...

Calcium in Aquaponics

Calcium in Aquaponic Systems – A Very Important Nutrient Calcium is one of the most important plant nutrients- in fact there are some who argue that it should be one of the primary plant nutrients, up there with nitrogen, phosphorus and potassium. A Common Nutrient in Aquaponics The fact that this is debated speaks to its importance in the plant growth cycle.  Calcium is a common nutrient in aquaponic systems and is not usually...

Modern Hydroponic Production: Why The Right People Are All Wrong

More To Successful Growing Than Just Productivity? After a busy weekend drawing up half a dozen wiring schematics for several new farms we’re putting in, I came home a little grumpy to a sick baby girl, and half a dozen notifications regarding a LinkedIn thread I’d recently commented on. In passing, I’d mentioned that our equipment was seeing great results with strawberry production, and immediately one of the LinkedIn experts chimed...

Solids Removal in Aquaponics

Solids removal is an important part of any aquaponic system. In raft systems this becomes expensive- you have to use some type of filtration to remove solids so that your raft beds don’t accumulate waste, your DO doesn’t crash, and your plant roots stay healthy. Media based techniques on the other hand, use the media bed to remove solids. Here at Bright Agrotech, we use our ZipGrow towers as mechanical filtration, sending almost all...

Wiggle Wire and Double Layer Greenhouses

Winter Winds and Wiggle Wire Greenhouse Designs This time of year the wind is whipping, the temperatures are plummeting and folks are asking about double layer poly coverings- the coverings of plastic film that we have on our greenhouses here at Bright Agrotech. We’ve been told over the years that what we’re doing doesn’t work, that poly can’t handle the windload, the snowload or the abuse that Wyoming winters tend to dish out.  Well,...

Diagnosing Potassium Deficiencies in Aquaponics

Recognizing Potassium Deficiencies Part #1) Introduction to Potassium Part #2) Potassium in Your System Potassium deficiencies can be difficult to diagnose, primarily because they resemble in many aspects, deficiencies in Calcium and Magnesium.  There are some distinguishing features however.  How Do I Know It’s A Potassium Problem? Potassium will typically show up initially as interveinal chlorosis, starting in the older...

Potassium in Your Aquaponics System (Part 2)

Potassium in Your Aquaponics System Potassium is almost always deficient in mature aquaponic systems unless it is supplemented. Plants, and especially flowering and fruiting plants, consume potassium at rates significantly higher than rates of input. This basically means that in order to have healthy plants, you’ll have to artificially bump up the amount of potassium in your system. Miss part 1? Read the Introduction to Potassium...
