im thinking im way behind just about everyone on this. i am gonna check for root gnats but i think its too cold to worry about those pests just yet. it rains but just very acidic. oh and the meter is new. i read the report on the change to chloramine and pushing the ph up to 9.2. they claim it will keep microbacteria under control for a longer period of time. well see what the ph's look like in a week or so on the pots i have, ill be mighty surprised if the one doesnt end up very high.
