Trees, Shrubs, Vegetables, and Flowers

An accurate soil test will help you indicate your soil's pH level, this will help you to determine the amount of lime or sulfur that will be needed to bring your pH level up or down to the appropriate level.
A pH of 6.5 is just about right for most home gardens, since most plants thrive in the 6.0 to 7.0 (slightly acidic to neutral) range. Some plants (blueberries, azaleas) prefer more strongly acidic soil, while a few (ferns, asparagus) do best in soil that is neutral to slightly alkaline.
Acidic (some call it sour) soil is counteracted by simply applying finely ground limestone, and alkaline (some call it sweet) soil is treated with gypsum (calcium sulfate) or ground sulfur.

Marihuana pH levels.

If you've done any research online pertaining to pH levels for marihuana, you will see that it will range from "in the area of" 5.5 to 6.5 or a bit higher. From experience, I believe that if you stay in the range of 5.8 to 6.2 "possibly up to 6.4" you are in the safe zone. "happy growing"


Important note:
It is imperative to pH when growing, as a seasoned grower I can honestly say that my water pH levels can fluctuate significantly when weather changes from cold to warm, wet to dry, change of seasons etc... etc... "Within a couple of days pH levels can change drastically."

When choosing a pH tester ensure you have a good one "check pH tester reviews online" as this can make the difference between a bad, ok and a very good grow. Do it right the first time.

When I ph my water / nutrients, my ph testing is redundant, I personally ALWAYS use 2 pH testers to ensure that no mistakes are being made, I calibrate often and I clean my ph tester after each and every nutrient ph test.
"I've personally experienced using a pH tester that was flawed in my past" Will NOT happen again!
