  • Effective but fleeting
Size: 1 Quart
I’ve been using Fox Farm pH Down to manage the acidity in my hydroponic garden, and a little truly goes a long way. It’s especially effective for quick adjustments when you’re working with standard setups. However, if you’re using tap water or have an organic system (I use bacillus along with some other beneficials for root rot), this might not be your best bet. The product’s effectiveness tends to wane faster under these conditions. The reason? It’s primarily citric acid-based, which organisms can metabolize quickly. This means it loses its pH-lowering power sooner than you might expect, leading to potential fluctuations in your system. For more stable pH control in organic setups, consider switching to a phosphorus-based pH down. This type will generally maintain its effects longer, keeping your garden’s acidity levels more consistent. ... show more

  • Foxfarm hits another home run. Just a little bit goes a long way
Size: 1 Quart
I love foxfarm products so I had to try their pH down. Just a little bit goes a long way so this bottle will last quite a long time.

  • Works great!

The original PH Down that came with our hydroponic system. Doesn't even come close to this! Works just as it should and better. It's a great price for the huge bottle!

  • Great product
Size: 1 Quart
Works fantastic, wish it was a tad cheaper. But it is a decent sized bottle. Since I only use about 18 drops for my water.

  • Best product on the market
Size: 1 Quart
Fox Farm hands down makes the best grow products out there. This stuff is so potent. My tap water comes out around 7-8 ph, and I want 6. I have a 6L hydro system and only need 1/8th of a tsp of this, which actually brings it down to 4 ph. I thought my PH tester was broken so I bought a new one, and it gave the same readings. ... show more

  • not stable at all.
Size: 1 Quart
I do both hydro and soil and i have a lot of plants. and this thing is great for one thing. ph'ing at the start. it only take a small amount which is great. but if you have the tech. like soil PH meter and other things that monitor your plants health. This stuff will not only change ph back to the orignal PH it was. but it wwill blow past it. for example. Hydro. i use RO water of course and when PH down to 5.7 ph for hydro. 3 hours later it jumps to 6.4. and it always does this... With soil it even worst. i will ph to 6.3 for soil and it will jump to 7.6 and this is wwith non organic soil. so it just medium and nothing else.... so this should not happen... the worst part is the soil depth. each depth has a different ph..... the moment i swapped to a different brand. my problems went away..... this stuff will change the ph in the soil and also change depending on the depth of the soil. not sure why. but i have a soil ph meter in each plant at different depth.... dont buy this stuff... also there soil is not great either if you watch a video it compare in blind fold test. ... show more
