MasterBlend Lettuce Formula NPK 8-15-36. MasterBlend fertilizers have been the go-to Hydroponic and Garden fertilizers for commercial growers for a long time. Their 8-5-36 Fertilizer (Lettuce Formula) provides proven results time after time. This formula has been specially formulated to use with Hydroponic lettuce crops. Because of the unique composition, it is recommended to use the 8-15-36 together with Magnesium Sulfate (Epsom Salt) and Calcium Nitrate for the ultimate balanced water soluble fertilizer.

  • MasterBlend Lettuce Formula 8-15-36 is fully Water Soluble
  • Direct from MasterBlend - Fertilizer for Tomatoes and Vegetables
  • Highly concentrated!
  • Master Blend fertilizer is perfect for Hydroponics and Soil gardens

It is recommended to use MasterBlend Lettuce Formula in conjunction with Calcium Nitrate and Magnesium Sulfate (also available) in the following recipes...

**IMPORTANT! Do not mix the 3 components together! Doing so will cause nutrient lockout and all the nutrients will not be available to your plants. You can mix the MasterBlend and Epsom Salts together, but not the Calcium Nitrate! Ideally you should mix each component separately in your water until thoroughly dissolved before mixing the next component.

Please note that using a scale that is accurate to grams is the best way to measure.

In 5 gallons of water, mix in the following order:

11 grams Masterblend - dissolve thoroughly
6.5 grams Epsom Salt - dissolve thoroughly
8.5 grams Calcium Nitrate- dissolve thoroughly

Functional and Good Quality
Color: 01-silver, Color: 01-silver
I give this SMARTAKE paper towel holder 4 stars. Overall, it's a very good product that I would recommend, but it has one minor drawback that takes away a star. The Positives Quality and Stability: The holder feels good quality, and the material (steel) is sturdy. Once placed on the counter, it's stable and adheres well to the surface. Assembly and Use: It was easy to put together; just read the instruction manual. I confirm that it works well even with large paper towel rolls. Furthermore, it's not difficult to change the roll at all. The Drawback The only problem is the small mechanism that's supposed to adjust and hold the roll (the piece that prevents it from twisting too much). As the paper gets used up, this piece doesn't do its job properly, and the paper unwinds more than it should. Conclusion: If you're looking for a modern, stable, and well-made holder for your kitchen, this is excellent. Just keep in mind that the adjuster isn't the best, but other than that, it does its job perfectly.
