Plant Nutrients – The “BIG THREE”: Nitrogen, Potassium, and Phosphorus

Posted by Jake Emling, CropKing Horticulturist on 10/10/2018

Nitrogen, Potassium and Phosphorus are crucial for plant health. As the seasons, and nutrient demands, of various crops change, I figured to start a three-part series highlighting the elements that are needed by most crops. To prevent these blog posts from becoming too large, I will be breaking them up to discuss the big three, the mighty macro’s, and the much-needed micros. I am not putting them in order of importance since all plants need all of these nutrients in one formula or another.

How CropKing NFT Channels Compare

Posted by Cropking on 10/23/2017

CropKing’s many years of research and growing experience have helped us determine the best equipment and growing methods for a variety of crops. When the goal is to produce high quality lettuce and herb crops, we recommend the NFT channel system. This recirculating system efficiently reduces water and fertilizer usage while maximizing production space. This growing system is an investment in the future of your business and every component is of the highest quality.

pH Should Stand for Plant Health!

Posted by Cropking on 7/18/2017

Plants are critical in our daily lives and many people take them for granted. We feed ourselves with plants, we feed our food with plants, we breath the oxygen from plants, they “breathe” our carbon dioxide, they keep the soil strong, and they do a lot more than what I can fit in this article. Bottom line: they are critical to our survival. Shouldn’t we respect plants as much we respect ourselves? Plants deserve to be just as healthy as we do, but they need some help from us!

Dutch Bucket Hydroponics

NFT channels are designed for growing small leaf crops such as lettuce and small herbs, but growing larger plants such as tomatoes, cucumbers, beans, and peppers in NFT channels is difficult, if not impossible. Large plants are usually more of a “long term” plant and need more root area than an NFT channels offers (they can also capsize the channels), so hydroponics (a lot of very large growers use hanging gutters and rockwool slabs. However for a smaller grower without all of the monitors and alarms, those rockwool slabs could dry out if the injection system failed in any way or was just not feeding enough to a growing plant. It is very difficult to “re-wet” it completely. Even if you flood it with water the water will tend to just wet area right around the roots. The water is looking for the easiest path and just flow along and around the roots. That is bad because as the plants continue to grow the roots will not branch out into the dry areas.

Hydroponic Fodder

With hay and grain costs on the rise and continuing drought immanent, many farmers and ranchers are looking to developing technology to assure the survival of their businesses. Although slightly counterintuitive, hydroponic food production has proven to be a great way to reduce overall water usage and still harvest a wonderful crop. CropKing’s hydroponic fodder system has been steadily gaining more interest as a feasible method for farmers to grow their own feed in order to greatly reduce their overall feed costs.

Hydroponic and Organic Plant Production Systems

Posted by Cropking on 1/16/2007

A question we frequently hear is whether a growing system can be both Hydroponic and “organic”. The answer can be complicated and depends upon how certain terms are defined, as well as preconceived ideas on the part of the individuals involved in the discussion.

Light in the Greenhouse: How much is Enough?

Posted by Jim Brown, Horticulturist on 11/16/2006

Most of us know that green plants need light for photosynthesis, growth, and development. As important as it is, however, that is not all there is to the role of light in plant growth and development. Plants respond in various ways to the intensity and duration of light. Let’s look at each of the ways that light affects plant growth.

Nutrient Film Technique in the Hobby Greenhouse

Posted by Jim Brown, Horticulturist on 5/9/2006

Many people want to have a small production system with which to grow fresh, leafy vegetables that they can enjoy year round. The nutrition of freshly harvested plants is superior to similar plants purchased at your local market. Plus, by growing your own, you have complete control over the treatment of any pest and disease that may occur. The control program that you implement in your hobby greenhouse can be one with which you are comfortable. You will know exactly what has been used on your own crops, eliminating the concerns over what chemicals or other products might have been used on commercially purchased produce while it was grown at a foreign production location or during its transport to your market.
