lowering PH?
How can I lower PH in my indoor garden. I am at around 7.0 and I want to get
to about 5.9 for my tomatoes. I have used aquarium product before but found it to be expensive. I am not sure what product to use that will not harm my plants as they are for human consumption... mon --- Outgoing mail is certified Virus Free.

If you work the compost into the soil using a tiller, the soil will become increasingly sour and chemicals will leach out. Acidic materials you can add include peat moss, sulfur, or aluminum sulfate. For your desired pH of 5.9, use 5 pounds of peat moss, 2.5 pounds of sulfur, or 15 pounds of aluminum sulfate per 100 sq foot of garden space. It is better to till in the additive than just spread it over the ground. You'll need less of the additives for sandy soil and somewhat more for heavy clay soil. Changes in pH do not happen overnight. Test pH again in 6 months. I've grown tomatoes for many years and never had concern about pH. Temperature seems to be more of a problem. |

lowering PH?
this is an indoor garden as my area is to cool to grow out doors for good
results with my chilies and tomatoes.. I am looking for a way to ph my water. I am growing in sphagnum peat moss,vermiculite/perlite/worm casting medium..just want to get my water ph correct for veg and flower.. I do regular flushing of the pots but I want to know how to ph the water I feed and flush with.. I heard dolomite lime is 7.0 and you can top dress pots.. and vinegar works but how much to lower from 7.8 to 6.0 .. also I heard citric acid can work.. any other ideas.. mon "Phisherman" wrote in message ...

lowering PH?
Coffee grounds I just put all my coffee grounds in my tomato garden
i noticed a differance in the health of my tomatoes when I use them as compared to when I don't. and they do slowly raise acid levles in a garden spot. and my neighbors swear by the ashes from their grill but I don't have a charcoal grill so I don't know about that .

Muriatic acid (31% HCl) a doses of approximately 2 fluid ounces per 1000 gallons per day until you reach the desired pH. The acid consumes the KH (alkalinity or carbonate hardness, the thing that stabilizes pH in a fish pond.). Muriatic acid is used for cleaning concrete and you can buy it in the building supply section of Lowe's or other hardware type stores for a few dollars a gallon and that will last you a long time. Always pour acid into the water. Never pour water into the acid! Regards, Hal |

A decent soil rich in organic materials such as leaf mold will probably do fine with no ammendment. |

I believe that Mon wants to lower the pH of a hydroponic nutrient
solution not soil. The best thing to use is phosphoric acid. That is what is in the pH down products available from stores that sell hydroponic supplies. Try www.wormsway.com. This should be safe for veggies. If you want a cheaper solution you can try getting some 85% phosphoric acid from a chemical supply house. Try daigger.com or vwrsci.com. If you get the 85% stuff, dilute it carefully 1:3 before using. Add phosphoric acid SLOWLY over the course of several days as there is the potential for quick changes in pH which will not make your plants happy.
