In this video I’ll show you how to mix masterblend nutrients correctly and how to run a sterile reservoir using common (and cheap) pool shock. This mixture can also be used in the AC Infinity self watering bases so make sure to check that video out too!
Masterblend synthetic nutrients has been my go-to for about a year now. I’ve used MB in everything from water (DWC Hydro) to soil to coco coir. As an added bonus, I love how there is no dye in MB and there is zero powder (particles) floating around the air when you open the bag. Read more @ masterblend.com.

About the N-P-K of Masterblend’s Tomato formula:
You’ll notice the N-P-K is 4-18-38 only when using this by itself.
When mixing in the Calcium Nitrate & Magnesium Sulfate it does NOT equal 19.5-18-38. I spoke to 2 different Masterblend reps on the phone and they both confirmed – you need to divide the NPK numbers because it goes by weight. The actual NPK when using all 3 products (at a normal 2:1 ratio) comes out to 8-7-15.

Pool shock (commonly found at Walmart too!)
The ingredients of the pool shock I use are 52% calcium hypochlorite & 48% other ingredients.
Other mixtures may work, I have not tried them.
To make the pool shock solution:
Add 1 gram of pool shock to 1 gallon of water and dissolve thoroughly.
(Or .1 gram per 12 ounces water).
This solution is what you will add into your nutrient mix at the recommended dosage per the mixing chart download above.
e.g. to sterilize a 5 gallon mixture, add 30 milliliters of the pool shock solution.
