well, I wish you luck...the truncheon is a good meter, imho...the only reason I don't have one is the cost.
when I researched meters...blue labs truncheon was my 1st choice.

My sm301 cost the same. but I bought it off ebay for 50 bucks. I am not familiar with the nutes you use.

anyway, If you have problems, let us know. lw
latewood Reviewed by latewood on . is 1600 ppm too high ??? hello-i have a garden of ladies that are 4 weeks into flowering. i have steadily been raising the ppm over the weeks. i kept them around 6-700 during veg and around 900-1000 for the last month. this morning i wanted to step them up a little and raised it to 1680 ppm. i have one of those truncheon meters that measures EC, ppm and something else(can't remember-wake and bake:rasta: ) so i expect that my ppm reading isn't exactly precise but i was wondering if i should keep it around 16-1700 or if Rating: 5
