The Problem With Hyperaccumulators: How to tell if you have contaminants in your Cannabis product.

Plants with the capability of accumulating heavy metals above concentrations that would typically cause harm or toxicity in plants are known as hyperaccumulators. Cannabis is a well-known hyperaccumulator with the ability to remove heavy metal contaminants from soils. This characteristic is desirable for soil remediation but troublesome when cannabis is grown for consumption.

If the nutrients you use are contaminated with heavy metals, your buds will be accumulating these heavy metals, exposing those who consume them.

How can you tell if you have heavy metal contaminants in your final cannabis product?

We care about heavy metals just as much as you do

Licensed producers of cannabis are required to test their finished products for heavy metal contaminants. Plant-Prod® is pleased to make heavy metal analysis results available to growers for our Plant-Prod MJ™ water soluble cannabis fertilizers line. When cannabis growers are aware of heavy metal levels in their crop inputs, they can anticipate potential levels within their buds.

Do My Plants Need Calcium? How Much Calcium To Feed Your Plants

Blog,

If you’re familiar with the classic milk advertisements praising calcium as a great way to build strong teeth and bones, then you shouldn’t be surprised to know that calcium is also essential for the “bones” of your plants (cell walls). 

The problem is, that knowing how much calcium to feed your plant is not always clear. Luckily Plant-Prod has over 75+ years of experience formulating water soluble fertilizers like Plant-Prod 15-0-15 Cal-Plus and Plant-Prod MJ™ Cal Kick. 

In this post, we’ll explain how much calcium you should be feeding your plant for the best results.

How Do I Know If My Plants Need Calcium?

All plants require a calcium source. Whether it’s coming from your water source or your
fertilizer program, calcium is an essential secondary nutrient. When it is lacking, there are some
tell-tale signs that are specific to calcium:

  • Low growth rate
  • Variable patterns of chlorosis on young leaves
  • Upward curling of leaves
  • Browning/necrosis of apical meristems (growing points)

There are also other plant-specific signs of calcium deficiency like blossom end rot in peppers and tomatoes.

How Much Calcium To Feed?

How much calcium to apply and when you apply it is difficult to generalize for all types of
plants. Depending on the crops you are growing, you might need to seek further information by
contacting us here, or visiting our crops section for specific recommendations. As a general
rule, the amount of calcium in your water source and your crop will be the main
determining factors dictating how much calcium to feed.

Depending on the demands of your crop and the growth stage that it is at, calcium can be fed
between 50-200 ppm Ca. The initial amount in your water source can contribute to this over all
ppm level and should be taken into consideration when determining fertilizer rates.

Calcium based fertilizers should be fed as part of a balanced fertilizer program. This means
alternating feedings with a traditional NPK fertilizer, such as Plant-Prod 20-10-20 High Nitrate
or Plant-Prod 20-20-20 Classic.

The quality of the water soluble calcium fertilizer you use can also affect the growth of your
plants. Be sure you’re getting what you paid for when purchasing a water soluble calcium
fertilizer and that it’s dissolving completely. (Plant-Prod water soluble fertilizers won’t end up at
the bottom of your tanks or undissolved in spray bottles).

Introducing the Plant-Prod Duo-ToteTM

Blog, , , , , , , , ,

The new way to tote

 
Plant-Prod® provides soluble fertilizers to customers both in bags and in bulk. Customized formulations that are delivered in bulk simplify and speed up the preparation of large tanks of fertilizer solution. However, material compatibility limited the range of formulations available. This limitation is now behind us.

Our new Duo-ToteTM has two compartments which keep incompatible ingredients apart, avoiding caking and melting, and allowing the delivery of all formulations. The contents of the Duo-Tote can be released at the same time where they dissolve quickly and without precipitating. Suitable for larger growers, the benefits of the Duo-ToteTM are many:

One tote per tank – faster & easier

  • Formulated specifically for your size of tank and plant nutrition needs.
  • You need just one Duo-ToteTM per tank, which is simple to use and minimizes the possibility of operator error.
  • The Duo-ToteTM can be lifted over the tank using a hoist or forklift. The drawstring on the bottom releases the fertilizer into the tank.
  • No need to take delivery of numerous bags, each requiring time to open, lift and empty.
  • Speed up operations. Our customers report time savings of 75%.

On July 15-18 we will be in Columbus, Ohio for the Cultivate’17 trade show. We will be showing the new Plantex by Plant-Prod Duo-Tote™ which is a new bulk packaging format for pre-mixed plant nutrition formulations. It is suitable for larger growers and is quicker and easier to use than bags, giving time-savings for mixing a large tank of around 70%.

Nutrients in the correct proportions can be customized to the specific requirements of each grower and their water conditions.  Incompatible ingredients co-exist in separate compartments. This new delivery format makes it quicker and more reliable for greenhouse staff to prepare the optimal concentration in the solution tanks.

A Plant-Prod Water Soluble Fertilizer Growing Story: Leading Taiwanese orchid grower grows over 10,000 orchids a year.

Reviews, , , , , , , ,
The Plant-Prod team visiting orchid breeder and grower Mr. Jiang Fulai.

Mr. Jiang Fulai grows orchids in Pingtung County at the southernmost point of Taiwan. He specializes in cultivating Renathera orchids, and sells the cut flowers to a market hungry for the crimson-red, kidney-shaped flowers that have been revered in Chinese culture for centuries. Mr. Jiang has used Plant-Prod water soluble fertilizers exclusively for the last thirty years.

Orchid growing conditions in Taiwan

Taiwan is a small island nation 180km east of China.

The climate in southern Taiwan is tropical, ideal for growing orchids. Surrounded by the Pacific Ocean, there is no risk of frost and no need for greenhouses. Plants only need to be shaded from direct sunlight.

In Taiwan, the economics of plant cultivation are significantly different from North America.

It is a small island, the same size as Maryland, with a population of 24 million. Two thirds of the island is rugged mountains, while this population, together with the booming manufacturing sector, are squeezed into a small area remaining. That means land is expensive. In comparison, an acre of agricultural land in the United States costs on average $3,000, while you can expect to pay about $15 million per acre in Taiwan.

Growing 10,000 plants with water soluble fertilizer

Mr. Jiang: “This is my laboratory.”

Mr. Jiang has been cultivating orchids for thirty years, refining methods to maximize productivity. His operation is supported by the Plant-Prod distributor, EverSing. Most of the time he employs Plant-Prod 20-20-20 water soluble fertilizer, applying every 7-10 days during the growing phase, followed by Plant-Prod 10-52-10 to induce flowering and strengthen the plant. During periods of high temperatures and rainfall, Mr. Jiang turns to Plant-Prod 8-20-30 to prevent overly leggy plants.

Mr. Jiang states that Plant-Prod nutrition is key to his  remarkable levels of productivity. “Each season we can harvest 10,000 flowers from 6,000 plants,” he states, “which is the same number of flowers that a competing operation produced from 10,000 plants”.

Maximizing plant yield by focusing on plant health

Mr. Jiang (second from left) shows Sanda Jovasevic, Plant-Prod Sales and Marketing Manager (third from left) the results of Plant-Prod fertilizers on his plants.

Orchids are one of the highest value plants cultivated by professional growers, and one of the most sensitive. Plant health needs to be protected and saving a few pennies by using a typical grade fertilizer is unwise.

Plant-Prod water soluble fertilizer is formulated with quality and consistency that is unmatched in commercial fertilizers. Mr. Jiang’s experience is a testament to Plant-Prod’s commitment to maximizing productivity of high value crops.

“When using competing fertilizers, the productivity is about 40% lower,” explains Mr. Jiang in an article on the EverSing website.

In May 2017 Sanda Jovasevic, Plant-Prod Sales and Marketing Manager accompanied by Jane Liu of EverSing visited Mr. Jiang’s operation. Following are photos from their visit.
