PH OF WATER: Satisfactory Range

Author is Robert M. [Bert] Hamilton (Compiler), posted almost 8 years ago 7 is recommended A78-309; other pH possibilities are: 8.0 to 8.4 is completely satisfactory; 7.2 or 8.4 should not be tampered with, depending on the locality; between 5.0 and 5.6 (medium strong ac... Read More

CARBON DIOXIDE: Ethanol and Methanol Alcohol Burning to Heighten Carbon Dioxide Content of Air

Author is Robert M. [Bert] Hamilton (Compiler), posted almost 8 years ago Satisfactory if burned in greenhouse in small amounts; alcohol flame is invisible by day and dangerous. A69-242 Read More

PH OF WATER: Cymbidiums

Author is Robert M. [Bert] Hamilton (Compiler), posted almost 8 years ago The best pH for them is not so much a matter of pH as to make sure the water is low in salt content. A70-725Their requirement is around 7.0. A78-713 Read More

PH OF WATER: Citric Acid Used

Author is Robert M. [Bert] Hamilton (Compiler), posted almost 8 years ago Local water supply was highly alkaline, pH of 10.5, and was lowered to 5.5 twice weekly using a Hydromix proportioning unit; a drop or two of food coloring was also added. A72-1003 Read More

PH OF WATER: Tree Habitats

Author is Robert M. [Bert] Hamilton (Compiler), posted almost 8 years ago Rain water has a low pH; activity of fungi, bacteria, lichens, algae etc. on bark, plus leaf leaching produce an acid state through production of organic acids; fungi normally like a pH of 4.5 to 6... Read More

Author is Robert M. [Bert] Hamilton (Compiler), posted almost 8 years ago If it has a pH of 5 and contains 105ppm. of calcium it is a suitable pH and is not excessive in calcium. A78-812; A80-739 Read More

FERTILIZERS: Organic or Inorganic

Author is Robert M. [Bert] Hamilton (Compiler), posted almost 8 years ago Bacterial activity is low at 50 deg.F. (10 deg.C.) so it is better to use inorganic types of fertilizer in cold weather;use an organic in warmer temperatures. AU73-185Both can be used; liquid organ... Read More
