I went to a bunch of gardening shops today, none of them have heard of canna, or fox farms, or any of the other brands that are highly recommended on here. I think Im just gonna buy some of whatever they have, as long as its organic, and not MG. What numbers should I be aiming for? Mostly nitrogen?


Also not having much luck with my ph research. I used the pool drops to test my tap water. Looks to be 6.8-7 but i cant really tell because of the inaccuracy of this testing method. I tried filtering the runoff with a coffee filter, but it didnt make it any less brown. I also let the runoff water sit in a cup overnight, to see if it would "settle" It didnt, which means the color isnt due to particle suspension, and explains why filtering it didnt do anything.

Today at lunch I drove around to a few aquarium/fish stores in search of a digital ph meter. Only 1 of the places even had a digital one, and it was $110 plus tax. Maybe one day when I win the lottery, untill then its gonna have to be a 20-30 dollar model off ebay. As much as Id prefer to support a local merchant, im not gonna scarifice my kids christmas presents to do so.
How much should I be looking to pay for a digital one?
