Alkaline water is water that’s less acidic than regular tap water. This means it is rich in alkalizing compounds, including calcium, silica, potassium, magnesium, and bicarbonate.pH.
The pH of the water that is used to mix your nutrient solution should always be checked before you begin to create the solution.
What is the PPM Scale
Part Per Million or TDS tells us how much salt is within our nutrient solution. Can be confusing but well worth understanding if you are mixing any type of bottled nutrients.
Water in the air
We never really think about the water the plants are putting off in our grow rooms. Transpiration, is what its called. This can cause some problems in the grow room if you do not pay attention. Understanding this and looking at the humidity (RH) in your grow room, you can gain control of the humidity by dialing it in to the plants specifications.
