Ph and ec in batmix??

I don't regulate PH when growing in soil/earth Outside. Inside is a bit different the growing containers are much smaller vs in earth. Batmix soil, = Peat, perlite, worm castings, Bat Guano. more soil less vs soil. quote from webpage on the question of do u need ph/ec balance: No, combined with our 100% NATURAL Grow Style you don't have to regulate the pH and EC value. https://www.plagron.com/en/products "100% NATURAL" is the lines name of nutrients they use. notice it in all caps?? If you don't use their products you need to PH and EC monitor.
