Sine wave inverters with more than three steps in the wave output are more complex and have significantly higher cost than a modified sine wave, with only three steps, or square wave (one step) types of the same power handling.
A healthy cell has a pH of 7.35 while a cancer cell is more acidic. Cesium when taken orally will raise the pH of cancer cells, but not that of normal cells. When the pH of a cancer cell goes above 7.5 it dies and if it goes above 8.0 it will die in a matter of hours.
That is, a nutrient solution with a Ph of 6.0 is ten times as acidic as a nutrient solution with a Ph of 7.0. A Ph difference of 2.0 is equal to a hundred times increase or decrease in Ph. It is essential to keep the Ph levels within certain limits when growing cannabis. The Ph level of your soil will ascertain how well your cannabis plants are able to take up the nutrients. If the Ph level is out of the correct range, the growth rate of the plants can stall or even stop.
