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.

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%.

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.
