General Hydroponics pH Control Kit Adjust for 8oz pH Up and Down GH Includes 5 Pipettes and Bonus Hydro Empire 4oz Measuring Cup Bundle. The Best GH pH Test kit for hydroponic Gardens on The Market!

Asin: B07DKG8PM2

General Hydroponics ph up and down kit contains 8 oz pH UP, 8 oz pH DOWN, 1 oz indicator and vial and 5 pipettes for safe and easy pH level detection.

This base solution is formulated using potassium hydroxide and potassium carbonate. Add a little at a time when your nutrient pH is too low in order to raise the pH to the proper level. This powder based formula is made to raise the pH in a reservoir. Lightweight in comparison to liquids.

Acid formulated using food grade Phosphoric acid. Just add a little at a time if your nutrient pH is too high in order to lower the pH to the proper level.

What is the right Soil pH Level for my Plants

A pH of 6.5 is just about right for most home gardens, since most plants thrive in the 6.0 to 7.0 (slightly acidic to neutral) range. Some plants (blueberries, azaleas) prefer more strongly acidic soil, while a few (ferns, asparagus) do best in soil that is neutral to slightly alkaline.

Pipettes:

Volume: 3ml. These soft pliable pipettes could save your time when adding accurate amounts of ph UP or Down into your vile for ph adjustment. Know more when transferring liquids with the added easy to read graduated lines at 0.5 ml. Some people even use these 3 ml pipettes for aromatherapy to use when measuring out fragrant essential oils. This sturdy plastic is clear so you can easily see the liquids you are measuring. So easy to use in your garden or indoor grow.

Hydro Empire 4oz Measuring Cup BONUS:

Measures 4.375" wide and 2.33" tall and features easy to read measurements including: cup, ounces, milliliters, cc's molded right into the cup so you never have to worry about ink lines.

Features

Bluelab pH 4.0 Calibration Solution 500 ml, pH 7.0 Calibration Solution 500 ml

 PartNumber: BL-COMBO-1   |   Asin: B01GQVSQGG

Calibration and conductivity standard solutions... a must in every grower's toolbox. The Bluelab calibration and conductivity standard solutions are essential for use with all Bluelab products for the calibration of pH and testing the cleanliness of the Bluelab Conductivity/Temperature probe. Bluelab solutions are manufactured specifically for Bluelab products and are referenced to high laboratory standards to ensure your Bluelab products last longer and maintain accuracy. Bluelab's EC/CF equipment does not need calibrating as they are all factory calibrated here at Bluelab. The CF27.7 (EC2.77) solution is used as a reference or checking solution to ensure you have adequately cleaned the EC/CF probe. Contamination between solutions can easily occur, which will affect the validity of the calibration. Bluelab recommend that the solutions are de-cantered into a smaller vessel and the contents discarded when the calibration process has been completed.

Features

  • Essential for use with all Bluelab pH products for the calibration of Bluelab pH Probes.
  • Make sure your pH Meter is Accurate!
