I have a question to pose i am looking for the range for TDS (total dissolved solvents) and EC (electro-condutivity) for soil. Read through the forums and it touches on these subjects but i have not seen an actual chart or anything. Thanks in advance.

TDS and EC range for soil

My TDs speaks ppm's not Ec tho their is a math formula someplace
To get an EC value, multiply the ppm reading by 2 and divide by 1000.
Thus, if your EC is 1:
1*1000/2= 500 ppm.
And if your ppm is 500:
500*2/1000= 1 EC is typical

Soil is a solid, dissolved solids are suspended in water. Are you talking about the feed water?
Now EC can be measured in soil. Mine averages around 1.8 DS/m.4x4 600w HID empty for summer
3x3 400w HID with Bruce Banner and Skywalker Kush
2x2 65w Quantum Board LED with 4 mother strains
running all simultaneously for a perpetual harvests.
