General Hydroponics pH Up Liquid Fertilizer, 1-Quart - 2 Pack

The General Hydroponics pH Up Liquid Fertilizer has received positive feedback from customers who have used it to balance the pH levels in their hydroponic systems. One customer mentions that they had previously struggled with pH issues, but after using this product, those issues became a thing of the past. They even go so far as to humorously suggest that it can be used as a remedy for PMS symptoms by passing the XL bottles around. Another reviewer states that the product works well and that 1 tsp of it is enough to raise the pH of 2 gallons of water by about 0.3. However, there is also a suggestion for improvement. One customer mentions that the product would be better if it came in a bottle with a squirt top. They have found a workaround by punching two holes in the current bottle - one for controlled pouring and another for air intake. They suggest that a "sport bottle" top would be a great addition to the packaging. Overall, customer experience with the General Hydroponics pH Up Liquid Fertilizer seems to be positive, with customers reporting success in raising pH levels and achieving healthy plant growth.
