General Hydroponics pH Control Kit - 4 Piece - pH Up, pH Down and Test Indicator - Pickup in Store Only
The General Hydroponics pH Control Kit is a complete set for measuring and correcting reservoir pH. The pH test indicator reads from pH 4.0 to 8.5; then pH Up or pH Down brings the solution back into range. Most crops do best at about pH 5.5 to 6.5.
- Includes 8 oz pH Up, 8 oz pH Down, 1 oz pH Test Indicator and a test vial
- Test: add 3 drops of indicator to a vial filled halfway and compare to the color chart
- Adjust only after nutrients are fully mixed in fresh water; stir and re-test
- Never mix undiluted pH Up and pH Down
- No batteries or calibration needed
Pickup in store only because the kit contains corrosive liquids.
