Don’t buy this.
If I could give less stars I would! The PH Down is super weak.
Trikie_Dik –
Works as advertised, but not as strong as General Hydroponics.
Iâm reading this at three out of five stars not because it didnât work, but because it required a lot more solution to balance my tapwater compared to other brands. I almost had to use twice as much of this pH up compared to the general hydroponics, but canât attest to the pH down as I never needed to use it.The indicator solution worked well, the solution actually worked and adjusted my water, I just burned through the bottle way faster than I should have. Going forward Iâll stick with general hydroponics but this would work in a pinch!
