So after attempting to do vegetative state without ppm concentration, I have decide that for flower I would like to push the plants and need to know my concentrations from day to day.
I have been keeping pH with drops, which has worked fine and been very easy. I can even tell when i between full numbers by the tint of the color that I see so I don't really want to spend the 150 on one of those pH/ ppm meters. I JUST want a solid, reliable, ppm meter that if possible is in the $20-$50 range IF they exist. I have seen ppm pens for $15.00 on ebay but I want to make sure that it wont last me a day or two, or just give me unreliable readings that will lead to me killing or hurting my plants.
If any of you guys could point me the correct direction, I would appreciate it. Thanks.
