Jack’s Nutrients by JR Peters

Soluble. Available. Consistent.

Since 1947, these are the three words that you have come to expect when you open a bag of fertilizer made by the Peters’ Family — and now, the master-crafters at Jack’s introduce our small batch blends, Jack’s Nutrients: A collection of formulas that gives you choices that work for many different controlled environments without the hype or confusion of extravagant names and crazy labels.

Our Company

Welcome.  You have come to JR Peters Inc. to find the highest quality and truly soluble nutrients blends on the market.  How can we say that?  Because we are here watching over every step of the process.  From research and formulation design in our small batch lab, through the intense qualifying of the purest raw materials according to our QC standards, to our long time employees watching over each handcrafted batch on our blending lines.  The family at JR Peters ensures that the nutrients that are in our fertilizers, that you are giving to your plants, meet the strictest standards and will grow the highest quality plant material.

The Lab

Our onsite laboratory is the heart of our fertilizer family, the process always begins in the lab. What we have seen over the last few years is a great influx of people looking for some knowledge about how to get started with their operation without the confusion of consultants or hours spent on the web. From there we started focusing our hydroponic and cannabis growers to a testing program that helps them navigate how to get started growing.

Our Hydro Track and Nutrient Track programs are designed to be a tool kit of knowledge for a grower. Both new growers and those who have quite a bit of experience learn to understand what they are starting with in regards to their fertility.  These testing kits create a blueprint on how to grow your plants and what nutrients and additions you may need to use.  The technical support team at JR Peters then helps guide the grower to nutritional success.

Technical Support

We listen to you.  That’s right, we actually have real people here to listen and help you decide which formula is right for your growing environment.  Some say it’s as easy as ABC or 123 but we know that it’s not.  Our highly trained and personalized technical staff will answer your questions and walk you through everything you need to know from result interpretation from our onsite lab, to formula choice and to mixing advice.

Jacks321

What is #Jacks321? Have you read about Jack’s 321 or seen the hashtag on insta?

Jack’s 321 is our tried and true two-part fertilizer program. It consists of Jack’s Nutrients Part A  5-12-26, Jack’s Nutrients Part B 15-0-0  and Epsom Salts. BUT where does that “321” come from, you ask? It’s the shortened amount of each fertilizer in grams per gallon.

To mix up the perfect blend of Jack’s 321 you will need:

 3.6 grams Part A

 2.4 grams Part B

1.1 grams of Epsom salts

This will give you a blend of nutrients for growing almost any controlled environment crop, in any growing system. The order of additions is VERY important. You must add the 5-12-26 first and make sure it is completely dissolved, then add in the Epsom salts making sure it is completely dissolved, then finally the calcium nitrate.
