I have been using General Hydroponics Ph UP and Down for 10 years. As mentioned on this site, Ph Down is strong stuff with only a few drops can bring down a gallon of liquid. However, Ph Up is not very strong and requires more to achieve a similar affect. What surprises me is how much Ph Up I have to use. My nutrients are the Fox Farm Dirty Dozen mixed in distilled water. The nutrient solution, before adjusting, is around 3.4. To get it to 6.5 I have to add 20ml of Ph Up. This seems like a lot. Certainly more than one is led to believe by the product details. What has been your experiences?

I just use the trio at 1/2 strength. My untreated well water has a pH of 5.3. When using all three I have to use about 5 ml/gal of GH pH up. Im pretty sure the Tiger bloom is the most acidic of the three. Not sure about the rest of the dirty dozen. Never used them. -
I'm using more down than up. I don't need much. If I don't add calmag in flower I have to up it a bit. The Si I use in veg is around 8.2pH I think. My water is stored rainwater so that seems to vary a bit depending on rain amount and frequency.Flower Room: 11' x 7' x 7.5'H, 480w AC, 13gal/day dehumidifier, 1.5gal ultrasonic humidifier, 60gal (27gal usable) nute tank, 16" pedestal fan & 18" wall fan.
