Re: How much will you pay for convience? I mix my dry ferts up in to bottles with DI H2O, and they last a couple months or more of dosing. 3 bottles dosing 1ml for every 2L of column for standard EI makes the entire system dead easy to use and remember.
I would pay more for lab grade accuracy and tested batches with high quality test kits, if nothing for the peace of mind. I would not pay for home mixed ferts on a palm scale; I do that my self already.
